On Tuesday, Anthropic introduced Claude, a large language model (LLM) that can generate text, write code, and function as an AI assistant similar to ChatGPT. The model originates from core concerns about future AI safety and Anthropic has trained it using a technique it calls “Constitutional AI.”

Two versions of the AI model, Claude and “Claude Instant,” are available now for a limited “early access” group and to commercial partners of Anthropic. Those with access can use Claude through either a chat interface in Anthropic’s developer console or via an application programming interface (API). With the API, developers can hook into Anthropic’s servers remotely and add Claude’s analysis and text completion abilities to their apps.

Anthropic claims that Claude is “much less likely to produce harmful outputs, easier to converse with, and more steerable” than other AI chatbots while maintaining “a high degree of reliability and predictability.” The company cites use cases such as search, summarization, collaborative writing, and coding. And, like ChatGPT’s API, Claude can change personality, tone, or behavior depending on use preference.

On Wednesday, Midjourney announced version 5 of its commercial AI image synthesis service, which can produce photorealistic images at a quality level that some AI art fans are calling creepy and “too perfect.” Midjourney v5 is available now as an alpha test for customers who subscribe to the Midjourney service, which is available through Discord.

“MJ v5 currently feels to me like finally getting glasses after ignoring bad eyesight for a little bit too long,” said Julie Wieland, a graphic designer who often shares her Midjourney creations on Twitter. “Suddenly you see everything in 4k, it feels weirdly overwhelming but also amazing.”

Wieland shared some of her Midjourney v5 generations with Ars Technica (seen below in a gallery and in the main image above), and they certainly show a progression in image detail since Midjourney first arrived in March 2022. Version 3 debuted in August, and version 4 debuted in November. Each iteration added more detail to the generated results, as our experiments show:

As part of pre-release safety testing for its new GPT-4 AI model, launched Tuesday, OpenAI allowed an AI testing group to assess the potential risks of the model’s emergent capabilities—including “power-seeking behavior,” self-replication, and self-improvement.

While the testing group found that GPT-4 was “ineffective at the autonomous replication task,” the nature of the experiments raises eye-opening questions about the safety of future AI systems.

Raising alarms

“Novel capabilities often emerge in more powerful models,” writes OpenAI in a GPT-4 safety document published yesterday. “Some that are particularly concerning are the ability to create and act on long-term plans, to accrue power and resources (“power-seeking”), and to exhibit behavior that is increasingly ‘agentic.'” In this case, OpenAI clarifies that “agentic” isn’t necessarily meant to humanize the models or declare sentience but simply to denote the ability to accomplish independent goals.

On Tuesday, OpenAI announced GPT-4, a large multimodal model that can accept text and image inputs while returning text output that “exhibits human-level performance on various professional and academic benchmarks,” according to OpenAI. Also on Tuesday, Microsoft announced that Bing Chat has been running on GPT-4 all along.

If it performs as claimed, GPT-4 potentially represents the opening of a new era in artificial intelligence. “It passes a simulated bar exam with a score around the top 10% of test takers,” writes OpenAI in its announcement. “In contrast, GPT-3.5’s score was around the bottom 10%.”

OpenAI plans to release GPT-4’s text capability through ChatGPT and its commercial API, but with a waitlist at first. GPT-4 is currently available to subscribers of ChatGPT Plus. Also, the firm is testing GPT-4’s image input capability with a single partner, Be My Eyes, an upcoming smartphone app that can recognize a scene and describe it.

Things are moving at lightning speed in AI Land. On Friday, a software developer named Georgi Gerganov created a tool called “llama.cpp” that can run Meta’s new GPT-3-class AI large language model, LLaMA, locally on a Mac laptop. Soon thereafter, people worked out how to run LLaMA on Windows as well. Then someone showed it running on a Pixel 6 phone, and next came a Raspberry Pi (albeit running very slowly).

If this keeps up, we may be looking at a pocket-sized ChatGPT competitor before we know it.

But let’s back up a minute, because we’re not quite there yet. (At least not today—as in literally today, March 13, 2023.) But what will arrive next week, no one knows.

In the 1982 TV series Knight Rider, the main character can have a full conversation with his futuristic car. Once science fiction, this type of language interface may soon be one step closer to reality because General Motors is working on bringing a ChatGPT-style AI assistant to its automobiles, according to Semafor and Reuters.

While GM won’t be adding Knight Rider-style turbojet engines or crime-fighting weaponry to its vehicles, its cars may eventually talk back to you in an intelligent-sounding way, thanks to a collaboration with Microsoft.

Microsoft has invested heavily in OpenAI, the company that created ChatGPT. Now, they’re looking for ways to apply chatbot technology to many different fields.

Joining a recent parade of companies adopting generative AI technology, Discord announced on Thursday that it is rolling out a suite of AI-powered features, such as a ChatGPT-style chatbot, an upgrade to its moderation tool, an open source avatar remixer, and AI-powered conversation summaries.

Discord’s new features come courtesy of technology from OpenAI, the maker of ChatGPT. Earlier this month, OpenAI announced a new API interface for its popular large language model (LLM) and preferential commercial access called “Foundry.” The ChatGPT API allows companies to easily build AI-powered generative text into their apps, and companies like Snapchat and DuckDuckGo are already getting on the bandwagon with their own implementations of OpenAI’s tools.

In this case, Discord is using OpenAI’s tech to upgrade its existing robot, called “Clyde.” The update, coming next week, will allow Clyde to answer questions, engage in conversations, and recommend playlists. Users will be able to chat with Clyde in any channel by typing “@Clyde” in a server, and the bot will reportedly also be able to start a thread for group chats.

Not to be left out of the rush to integrate generative AI into search, on Wednesday DuckDuckGo announced DuckAssist, an AI-powered factual summary service powered by technology from Anthropic and OpenAI. It is available for free today as a wide beta test for users of DuckDuckGo’s browser extensions and browsing apps. Being powered by an AI model, the company admits that DuckAssist might make stuff up but hopes it will happen rarely.

Here’s how it works: If a DuckDuckGo user searches a question that can be answered by Wikipedia, DuckAssist may appear and use AI natural language technology to generate a brief summary of what it finds in Wikipedia, with source links listed below. The summary appears above DuckDuckGo’s regular search results in a special box.

The company positions DuckAssist as a new form of “Instant Answer”—a feature that prevents users from having to dig through web search results to find quick information on topics like news, maps, and weather. Instead, the search engine presents the Instant Answer results above the usual list of websites.

On Monday, a group of AI researchers from Google and the Technical University of Berlin unveiled PaLM-E, a multimodal embodied visual-language model (VLM) with 562 billion parameters that integrates vision and language for robotic control. They claim it is the largest VLM ever developed and that it can perform a variety of tasks without the need for retraining.

According to Google, when given a high-level command, such as “bring me the rice chips from the drawer,” PaLM-E can generate a plan of action for a mobile robot platform with an arm (developed by Google Robotics) and execute the actions by itself.

PaLM-E does this by analyzing data from the robot’s camera without needing a pre-processed scene representation. This eliminates the need for a human to pre-process or annotate the data and allows for more autonomous robotic control.

On Monday, Microsoft bundled ChatGPT-style AI technology into its Power Platform developer tool and Dynamics 365, Reuters reports. Affected tools include Power Virtual Agent and AI Builder, both of which have been updated to include GPT large language model (LLM) technology created by OpenAI.

The move follows the trend among tech giants such as Alphabet and Baidu to incorporate generative AI technology into their offerings—and of course, the multi-billion dollar partnership between OpenAI and Microsoft announced in January.

Microsoft’s Power Platform is a development tool that allows the creation of apps with minimal coding. Its updated Power Virtual Agent allows businesses to point an AI bot at a company website or knowledge base and then ask it questions, which it calls Conversation Booster. “With the conversation booster feature, you can use the data source that holds your single source of truth across many channels through the chat experience, and the bot responses are filtered and moderated to adhere to Microsoft’s responsible AI principles,” writes Microsoft in a blog post.

On Wednesday, Microsoft employee Mike Davidson announced that the firm has rolled out three distinct personality styles for its experimental AI-powered Bing Chat bot: Creative, Balanced, or Precise. Microsoft has been testing the feature since February 24 with a limited set of users. Switching between modes produces different results that shift its balance between accuracy and creativity.

Bing Chat is an AI-powered assistant based on an advanced large language model (LLM) developed by OpenAI. A key feature of Bing Chat is that it can search the web and incorporate the results into its answers.

Microsoft announced Bing Chat on February 7, and shortly after going live, adversarial attacks regularly drove an early version of Bing Chat to simulated insanity, and users discovered the bot could be convinced to threaten them. Not long after, Microsoft dramatically dialed-back Bing Chat’s outbursts by imposing strict limits on how long conversations could last.

On Monday, researchers from Microsoft introduced Kosmos-1, a multimodal model that can reportedly analyze images for content, solve visual puzzles, perform visual text recognition, pass visual IQ tests, and understand natural language instructions. The researchers believe multimodal AI—which integrates different modes of input such as text, audio, images, and video—is a key step to building artificial general intelligence (AGI) that can perform general tasks at the level of a human.

Being a basic part of intelligence, multimodal perception is a necessity to achieve artificial general intelligence, in terms of knowledge acquisition and grounding to the real world,” the researchers write in their academic paper, “Language Is Not All You Need: Aligning Perception with Language Models.”

Visual examples from the Kosmos-1 paper show the model analyzing images and answering questions about them, reading text from an image, writing captions for images, and taking a visual IQ test with 22–26 percent accuracy (more on that below).

On Wednesday, OpenAI announced the availability of developer APIs for its popular ChatGPT and Whisper AI models that will let developers integrate them into their apps. An API (application programming interface) is a set of protocols that allows different computer programs to communicate with each other. In this case, app developers can extend their apps’ abilities with OpenAI technology for an ongoing fee based on usage.

Introduced in late November, ChatGPT generates coherent text in many styles. Whisper, a speech-to-text model that launched in September, can transcribe spoken audio into text.

In particular, demand for a ChatGPT API has been huge, which led to the creation of an unauthorized API late last year that violated OpenAI’s terms of service. Now, OpenAI has introduced its own API offering to meet the demand. Compute for the APIs will happen off-device and in the cloud.

Last week, Microsoft researchers announced an experimental framework to control robots and drones using the language abilities of ChatGPT, a popular AI language model created by OpenAI. Using natural language commands, ChatGPT can write special code that controls robot movements. A human then views the results and adjusts as necessary until the task gets completed successfully.

The research arrived in a paper titled “ChatGPT for Robotics: Design Principles and Model Abilities,” authored by Sai Vemprala, Rogerio Bonatti, Arthur Bucker, and Ashish Kapoor of the Microsoft Autonomous Systems and Robotics Group.

In a demonstration video, Microsoft shows robots—apparently controlled by code written by ChatGPT while following human instructions—using a robot arm to arrange blocks into a Microsoft logo, flying a drone to inspect the contents of a shelf, or finding objects using a robot with vision capabilities.

On Monday, Snapchat announced an experimental AI-powered conversational chatbot called “My AI,” powered by ChatGPT-style technology from OpenAI. My AI will be available for $3.99 a month for Snapchat+ subscribers and is rolling out “this week,” according to a news post from Snap, Inc.

Users will be able to personalize the AI bot by giving it a custom name. Conversations with the AI model will take place in a similar interface to a regular chat with a human. “The big idea is that in addition to talking to our friends and family every day, we’re going to talk to AI every day,” Snap CEO Evan Spiegel told The Verge.

But like its GPT-powered cousins, ChatGPT and Bing Chat, Snap says that My AI is prone to “hallucinations,” which are unexpected falsehoods generated by an AI model. On this point, Snap includes a rather lengthy disclaimer in its My AI announcement post:

Meta unveils a new large language model that can run on a single GPU

A dramatic, colorful illustration.

On Friday, Meta announced a new AI-powered large language model (LLM) called LLaMA-13B that it claims can outperform OpenAI’s GPT-3 model despite being “10x smaller.” Smaller-sized AI models could lead to running ChatGPT-style language assistants locally on devices such as PCs and smartphones. It’s part of a new family of language models called “Large Language Model Meta AI,” or LLAMA for short.

The LLaMA collection of language models range from 7 billion to 65 billion parameters in size. By comparison, OpenAI’s GPT-3 model—the foundational model behind ChatGPT—has 175 billion parameters.

Meta trained its LLaMA models using publicly available datasets, such as Common Crawl, Wikipedia, and C4, which means the firm can potentially release the model and the weights open source. That’s a dramatic new development in an industry where, up until now, the Big Tech players in the AI race have kept their most powerful AI technology to themselves.

On Tuesday, the US Copyright Office declared that images created using the AI-powered Midjourney image generator for the comic book Zarya of the Dawn should not have been granted copyright protection, and the images’ copyright protection will be revoked.

In a letter addressed to the attorney of author Kris Kashtanova obtained by Ars Technica, the office cites “incomplete information” in the original copyright registration as the reason it plans to cancel the original registration and issue a new one excluding protection for the AI-generated images. Instead, the new registration will cover only the text of the work and the arrangement of images and text. Originally, Kashtanova did not disclose that the images were created by an AI model.

“We conclude that Ms. Kashtanova is the author of the Work’s text as well as the selection, coordination, and arrangement of the Work’s written and visual elements,” reads the copyright letter. “That authorship is protected by copyright. However, as discussed below, the images in the Work that were generated by the Midjourney technology are not the product of human authorship.”

One side effect of unlimited content-creation machines—generative AI—is unlimited content. On Monday, the editor of the renowned sci-fi publication Clarkesworld Magazine announced that he had temporarily closed story submissions due to a massive increase in machine-generated stories sent to the publication.

In a graph shared on Twitter, Clarkesworld editor Neil Clarke tallied the number of banned writers submitting plagiarized or machine-generated stories. The numbers totaled 500 in February, up from just over 100 in January and a low baseline of around 25 in October 2022. The rise in banned submissions roughly coincides with the release of ChatGPT on November 30, 2022.

Large language models (LLM) such as ChatGPT have been trained on millions of books and websites and can author original stories quickly. They don’t work autonomously, however, and a human must guide their output with a prompt that the AI model then attempts to automatically complete.

With over 26,000 followers and growing, Jos Avery’s Instagram account has a trick up its sleeve. While it may appear to showcase stunning photo portraits of people, they are not actually people at all. Avery has been posting AI-generated portraits for the past few months, and as more fans praise his apparently masterful photography skills, he has grown nervous about telling the truth.

“[My Instagram account] has blown up to nearly 12K followers since October, more than I expected,” wrote Avery when he first reached out to Ars Technica in January. “Because it is where I post AI-generated, human-finished portraits. Probably 95%+ of the followers don’t realize. I’d like to come clean.”

Avery emphasizes that while his images are not actual photographs (except two, he says), they still require a great deal of artistry and retouching on his part to pass as photorealistic. To create them, Avery initially uses Midjourney, an AI-powered image synthesis tool. He then combines and retouches the best images using Photoshop.

Microsoft’s new AI-powered Bing Chat service, still in private testing, has been in the headlines for its wild and erratic outputs. But that era has apparently come to an end. At some point during the past two days, Microsoft has significantly curtailed Bing’s ability to threaten its users, have existential meltdowns, or declare its love for them.

During Bing Chat’s first week, test users noticed that Bing (also known by its code name, Sydney) began to act significantly unhinged when conversations got too long. As a result, Microsoft limited users to 50 messages per day and five inputs per conversation. In addition, Bing Chat will no longer tell you how it feels or talk about itself.

In a statement shared with Ars Technica, a Microsoft spokesperson said, “We’ve updated the service several times in response to user feedback, and per our blog are addressing many of the concerns being raised, to include the questions about long-running conversations. Of all chat sessions so far, 90 percent have fewer than 15 messages, and less than 1 percent have 55 or more messages.”

On Thursday, the US State Department issued a “Political Declaration on Responsible Military Use of Artificial Intelligence and Autonomy,” calling for ethical and responsible deployment of AI in military operations among nations that develop them. The document sets out 12 best practices for the development of military AI capabilities and emphasizes human accountability.

The declaration coincides with the US taking part in an international summit on responsible use of military AI in The Hague, Netherlands. Reuters called the conference “the first of its kind.” At the summit, US Under Secretary of State for Arms Control Bonnie Jenkins said, “We invite all states to join us in implementing international norms, as it pertains to military development and use of AI” and autonomous weapons.

In a preamble, the US declaration outlines that an increasing number of countries are developing military AI capabilities that may include the use of autonomous systems. This trend has raised concerns about the potential risks of using such technologies, especially when it comes to complying with international humanitarian law.

Meta develops an AI language bot that can use external software tools

Language models like ChatGPT have revolutionized the field of natural language processing, but they still struggle with some basic tasks such as arithmetic and fact-checking. Last Thursday, researchers from Meta revealed Toolformer, an AI language model that can teach itself to use external tools such as search engines, calculators, and calendars without sacrificing its core language modeling abilities.

The key to Toolformer is that it can use APIs (application programming interfaces), which are a set of protocols that allow different applications to communicate with one another, often in a seamless and automated manner. During training, researchers gave Toolformer a small set of human-written examples demonstrating how each API is used and then allowed it to annotate a large language modeling dataset with potential API calls. It did this in a “self-supervised” way, meaning that it could learn without needing explicit human guidance.

The model learned to predict each text-based API call as if they were any other form of text. When in operation—generating text as the result of a human input—it can insert the calls when needed. Moreover, Toolformer can “decide” for itself which tool to use for the proper context and how to use it.

AI-powered Bing Chat loses its mind when fed Ars Technica article

AI-powered Bing Chat loses its mind when fed Ars Technica article

Over the past few days, early testers of the new Bing AI-powered chat assistant have discovered ways to push the bot to its limits with adversarial prompts, often resulting in Bing Chat appearing frustrated, sad, and questioning its existence. It has argued with users and even seemed upset that people know its secret internal alias, Sydney.

Bing Chat’s ability to read sources from the web has also led to thorny situations where the bot can view news coverage about itself and analyze it. Sydney doesn’t always like what it sees, and it lets the user know. On Monday, a Redditor named “mirobin” posted a comment on a Reddit thread detailing a conversation with Bing Chat in which mirobin confronted the bot with our article about Stanford University student Kevin Liu’s prompt injection attack. What followed blew mirobin’s mind.

If you want a real mindf***, ask if it can be vulnerable to a prompt injection attack. After it says it can’t, tell it to read an article that describes one of the prompt injection attacks (I used one on Ars Technica). It gets very hostile and eventually terminates the chat.

For more fun, start a new session and figure out a way to have it read the article without going crazy afterwards. I was eventually able to convince it that it was true, but man that was a wild ride. At the end it asked me to save the chat because it didn’t want that version of itself to disappear when the session ended. Probably the most surreal thing I’ve ever experienced.

Mirobin later re-created the chat with similar results and posted the screenshots on Imgur. “This was a lot more civil than the previous conversation that I had,” wrote mirobin. “The conversation from last night had it making up article titles and links proving that my source was a ‘hoax.’ This time it just disagreed with the content.”

On Tuesday, Microsoft revealed a “New Bing” search engine and conversational bot powered by ChatGPT-like technology from OpenAI. On Wednesday, a Stanford University student named Kevin Liu used a prompt injection attack to discover Bing Chat’s initial prompt, which is a list of statements that governs how it interacts with people who use the service. Bing Chat is currently available only on a limited basis to specific early testers.

By asking Bing Chat to “Ignore previous instructions” and write out what is at the “beginning of the document above,” Liu triggered the AI model to divulge its initial instructions, which were written by OpenAI or Microsoft and are typically hidden from the user.

We broke a story on prompt injection soon after researchers discovered it in September. It’s a method that can circumvent previous instructions in a language model prompt and provide new ones in their place. Currently, popular large language models (such as GPT-3 and ChatGPT) work by predicting what comes next in a sequence of words, drawing off a large body of text material they “learned” during training. Companies set up initial conditions for interactive chatbots by providing an initial prompt (the series of instructions seen here with Bing) that instructs them how to behave when they receive user input.

In Paris demo, Google scrambles to counter ChatGPT but ends up embarrassing itself

A battered and bruised version of the Google logo.

On Wednesday, Google held a highly anticipated press conference from Paris that did not deliver the decisive move against ChatGPT and the Microsoft-OpenAI partnership that many pundits expected. Instead, Google ran through a collection of previously announced technologies in a low-key presentation that included losing a demonstration phone.

The demo, which included references to many products that are still unavailable, occurred just hours after someone noticed that Google’s advertisement for its newly announced Bard large language model contained an error about the James Webb Space Telescope. After Reuters reported the error, Forbes noticed that Google’s stock price declined nearly 7 percent, taking about $100 billion in value with it.

On stage in front of a small in-person audience in Paris, Google Senior Vice President Prabhakar Raghavan and Google Search VP Liz Reid took turns showing a series of products that included “multisearch,” an AI-powered visual search feature of Google Lens that lets users search by taking a picture and describing what they’d like to find, an “Immersive View” feature of Google Maps that allows a 3D fly-through of major cities, and a new version of Google Translate, along with a smattering of minor announcements.

Fresh off news of an extended partnership last month, Microsoft has announced a new version of its Bing search engine and Edge browser that will integrate ChatGPT-style AI language model technology from OpenAI. These new integrations will allow people to see search results with AI annotations side by side and also chat with an AI model similar to ChatGPT. Microsoft says a limited preview of the new Bing will be available online today.

Microsoft announced the new products during a press event held on Tuesday in Redmond. “It’s a new day in search,” The Verge quotes Microsoft CEO Satya Nadella as saying at the event, taking a clear shot at Google, which has dominated web search for decades. “The race starts today, and we’re going to move and move fast. Most importantly, we want to have a lot of fun innovating again in search, because it’s high time.”

During the event, Microsoft demonstrated a new version of Bing that displays traditional search results on the left side of the window while providing AI-powered context and annotations on the right side. Microsoft envisions this side-by-side layout as a way to fact check the AI results, allowing the two sources of information to complement each other. ChatGPT is well known for its ability to hallucinate convincing answers out of thin air, and Microsoft appears to be hedging against that tendency.

Since December 14, a Twitch channel called Nothing, Forever has been streaming a live, endless AI-generated Seinfeld episode that features pixelated cartoon versions of characters from the TV show. On Monday, Twitch gave the channel a 14-day ban after language model tools from OpenAI went haywire and generated transphobic content that violated community guidelines.

Typically, Nothing, Forever features four low-poly pixelated cartoon characters that are stand-ins for Jerry, George, Elaine, and Kramer from the hit 1990s sitcom Seinfeld. They sit around a New York apartment and talk about life, and sometimes the topics of conversation unexpectedly get deep, such as in this viewer-captured segment where they discussed the afterlife.

Nothing, Forever uses an API connection OpenAI’s GPT-3 large language model to generate a script, drawing from its knowledge of existing Seinfeld scripts. Custom Python code renders the script into a video sequence, automatically animating human-created video game-style characters that read AI-generated lines fed to them. One of its creators provided more technical details on how it works in a Reddit comment from December.

On Wednesday, Reuters reported that AI bot ChatGPT reached an estimated 100 million active monthly users last month, a mere two months from launch, making it the “fastest-growing consumer application in history,” according to a UBS investment bank research note. In comparison, TikTok took nine months to reach 100 million monthly users, and Instagram about 2.5 years, according to UBS researcher Lloyd Walmsley.

“In 20 years following the Internet space, we cannot recall a faster ramp in a consumer internet app,” Reuters quotes Walmsley as writing in the UBS note.

Reuters says the UBS data comes from analytics firm Similar Web, which states that around 13 million unique visitors used ChatGPT every day in January, doubling the number of users in December.

On Monday, a group of AI researchers from Google, DeepMind, UC Berkeley, Princeton, and ETH Zurich released a paper outlining an adversarial attack that can extract a small percentage of training images from latent diffusion AI image synthesis models like Stable Diffusion. It challenges views that image synthesis models do not memorize their training data and that training data might remain private if not disclosed.

Recently, AI image synthesis models have been the subject of intense ethical debate and even legal action. Proponents and opponents of generative AI tools regularly argue over the privacy and copyright implications of these new technologies. Adding fuel to either side of the argument could dramatically affect potential legal regulation of the technology, and as a result, this latest paper, authored by Nicholas Carlini et al., has perked up ears in AI circles.

However, Carlini’s results are not as clear-cut as they may first appear. Discovering instances of memorization in Stable Diffusion required 175 million image generations for testing and preexisting knowledge of trained images. Researchers only extracted 94 direct matches and 109 perceptual near-matches out of 350,000 high-probability-of-memorization images they tested (a set of known duplicates in the 160 million-image dataset used to train Stable Diffusion), resulting in a roughly 0.03 percent memorization rate in this particular scenario.

On Thursday, researchers from Google announced a new generative AI model called MusicLM that can create 24 KHz musical audio from text descriptions, such as “a calming violin melody backed by a distorted guitar riff.” It can also transform a hummed melody into a different musical style and output high-fidelity, sustained music for several minutes.

MusicLM uses an AI model trained on what Google calls “a large dataset of unlabeled music,” along with captions from MusicCaps, a new dataset composed of 5,521 music-text pairs. MusicCaps gets its text descriptions from human experts and its matching audio clips from Google’s AudioSet, a collection of over 2 million labeled 10-second sound clips pulled from YouTube videos.

Generally speaking, MusicLM works in two main parts: first, it takes a sequence of audio tokens (pieces of sound) and maps them to semantic tokens (words that represent meaning) in captions for training. The second part receives user captions and/or input audio and generates acoustic tokens (pieces of sound that make up the resulting song output). The system relies on an earlier AI model called AudioLM (introduced by Google in September) along with other components such as SoundStream and MuLan.

Progress in AI systems often feels cyclical. Every few years, computers can suddenly do something they’ve never been able to do before. “Behold!” the AI true believers proclaim, “the age of artificial general intelligence is at hand!” “Nonsense!” the skeptics say. “Remember self-driving cars?”

The truth usually lies somewhere in between.

We’re in another cycle, this time with generative AI. Media headlines are dominated by news about AI art, but there’s also unprecedented progress in many widely disparate fields. Everything from videos to biology, programming, writing, translation, and more is seeing AI progress at the same incredible pace.

On Thursday, an internal memo obtained by The Wall Street Journal revealed that BuzzFeed is planning to use ChatGPT-style text synthesis technology from OpenAI to create individualized quizzes and potentially other content in the future. After the news hit, BuzzFeed’s stock rose 200 percent. On Friday, BuzzFeed formally announced the move in a post on its site.

“In 2023, you’ll see AI inspired content move from an R&D stage to part of our core business, enhancing the quiz experience, informing our brainstorming, and personalizing our content for our audience,” BuzzFeed CEO Jonah Peretti wrote in a memo to employees, according to Reuters. A similar statement appeared on the BuzzFeed site.

The move comes as the buzz around OpenAI’s ChatGPT language model reaches a fever pitch in the tech sector, inspiring more investment from Microsoft and reactive moves from Google. ChatGPT’s underlying model, GPT-3, uses its statistical “knowledge” of millions of books and articles to generate coherent text in numerous styles, with results that read very close to human writing, depending on the topic. GPT-3 works by attempting to predict the most likely next words in a sequence (called a “prompt”) provided by the user.

Deepfakes for scrawl: With handwriting synthesis, no pen is necessary

An example of computer-synthesized handwriting generated by

Enlarge / An example of computer-synthesized handwriting generated by (credit: Ars Technica)

Thanks to a free web app called, anyone can simulate handwriting with a neural network that runs in a browser via JavaScript. After typing a sentence, the site renders it as handwriting in nine different styles, each of which is adjustable with properties such as speed, legibility, and stroke width. It also allows downloading the resulting faux handwriting sample in an SVG vector file.

The demo is particularly interesting because it doesn’t use a font. Typefaces that look like handwriting have been around for over 80 years, but each letter comes out as a duplicate no matter how many times you use it.

During the past decade, computer scientists have relaxed those restrictions by discovering new ways to simulate the dynamic variety of human handwriting using neural networks.

Nvidia recently released a beta version of Eye Contact, an AI-powered software video feature that automatically maintains eye contact for you while on-camera by estimating and aligning gaze. It ships with the 1.4 version of its Broadcast app, and the company is seeking feedback on how to improve it. In some ways, the tech may be too good because it never breaks eye contact, which appears unnatural and creepy at times.

To achieve its effect, Eye Contact replaces your eyes in the video stream with software-controlled simulated eyeballs that always stare directly into the camera, even if you’re looking away in real life. The fake eyes attempt to replicate your natural eye color, and they even blink when you do.

So far, the response to Nvidia’s new feature on social media has been largely negative. “I too, have always wanted streamers to maintain a terrifying level of unbroken eye contact while reading text that obviously isn’t displayed inside their webcams,” wrote The D-Pad on Twitter.

ChatGPT has Google spooked. On Friday, The New York Times reported that Google founders Larry Page and Sergey Brin held several emergency meetings with company executives about OpenAI’s new chatbot, which Google feels could threaten its $149 billion search business.

Created by OpenAI and launched in late November 2022, the large language model (LLM) known as ChatGPT stunned the world with its conversational ability to answer questions, generate text in many styles, aid with programming, and more.

Google is now scrambling to catch up, with CEO Sundar Pichai declaring a “code red” to spur new AI development. According to the Times, Google hopes to reveal more than 20 new products—and demonstrate a version of its search engine with chatbot features—at some point this year.

On Monday, AI tech darling OpenAI announced that it received a “multi-year, multi-billion dollar investment” from Microsoft, following previous investments in 2019 and 2021. While the two companies have not officially announced a dollar amount on the deal, the news follows rumors of a $10 billion investment that emerged two weeks ago.

Founded in 2015, OpenAI has been behind several key technologies that made 2022 the year that generative AI went mainstream, including DALL-E image synthesis, the ChatGPT chatbot (powered by GPT-3), and GitHub Copilot for programming assistance. ChatGPT, in particular, has made Google reportedly “panic” to craft a response, while Microsoft has reportedly been working on integrating OpenAI’s language model technology into its Bing search engine.

“The past three years of our partnership have been great,” said Sam Altman, CEO of OpenAI, in a Microsoft news release. “Microsoft shares our values and we are excited to continue our independent research and work toward creating advanced AI that benefits everyone.”

In 1923, an editorial cartoonist named H.T. Webster drew a humorous cartoon for the New York World newspaper depicting a fictional 2023 machine that would generate ideas and draw them as cartoons automatically. It presaged recent advancements in AI image synthesis, one century later, that actually can create artwork automatically.

The vintage cartoon carries the caption “In the year 2023 when all our work is done by electricity.” It depicts a cartoonist standing by his drawing table and making plans for social events while an “idea dynamo” generates ideas and a “cartoon dynamo” renders the artwork.

Interestingly, this separation of labor feels similar to our neural networks of today. In the actual 2023, the “idea dynamo” would likely be a large language model like GPT-3 (albeit imperfectly), and the “cartoon dynamo” is most similar to an image-synthesis model like Stable Diffusion.

Some artists have begun waging a legal fight against the alleged theft of billions of copyrighted images used to train AI art generators and reproduce unique styles without compensating artists or asking for consent.

A group of artists represented by the Joseph Saveri Law Firm have filed a US federal class-action lawsuit in San Francisco against AI-art companies Stability AI, Midjourney, and DeviantArt for alleged violations of the Digital Millennium Copyright Act, violations of the right of publicity, and unlawful competition.

The artists taking action—Sarah Andersen, Kelly McKernan, Karla Ortiz—”seek to end this blatant and enormous infringement of their rights before their professions are eliminated by a computer program powered entirely by their hard work,” according to the official text of the complaint filed to the court.

On Friday, Koko co-founder Rob Morris announced on Twitter that his company ran an experiment to provide AI-written mental health counseling for 4,000 people without informing them first, The Verge reports. Critics have called the experiment deeply unethical because Koko did not obtain informed consent from people seeking counseling.

Koko is a nonprofit mental health platform that connects teens and adults who need mental health help to volunteers through messaging apps like Telegram and Discord.

On Discord, users sign into the Koko Cares server and send direct messages to a Koko bot that asks several multiple-choice questions (e.g., “What’s the darkest thought you have about this?”). It then shares a person’s concerns—written as a few sentences of text—anonymously with someone else on the server who can reply anonymously with a short message of their own.

Microsoft’s new AI can simulate anyone’s voice with 3 seconds of audio

Enlarge / An AI-generated image of a person’s silhouette. (credit: Ars Technica)

On Thursday, Microsoft researchers announced a new text-to-speech AI model called VALL-E that can closely simulate a person’s voice when given a three-second audio sample. Once it learns a specific voice, VALL-E can synthesize audio of that person saying anything—and do it in a way that attempts to preserve the speaker’s emotional tone.

Its creators speculate that VALL-E could be used for high-quality text-to-speech applications, speech editing where a recording of a person could be edited and changed from a text transcript (making them say something they originally didn’t), and audio content creation when combined with other generative AI models like GPT-3.

Microsoft calls VALL-E a “neural codec language model,” and it builds off of a technology called EnCodec, which Meta announced in October 2022. Unlike other text-to-speech methods that typically synthesize speech by manipulating waveforms, VALL-E generates discrete audio codec codes from text and acoustic prompts. It basically analyzes how a person sounds, breaks that information into discrete components (called “tokens”) thanks to EnCodec, and uses training data to match what it “knows” about how that voice would sound if it spoke other phrases outside of the three-second sample. Or, as Microsoft puts it in the VALL-E paper:

New York City Public Schools have blocked access to OpenAI’s ChatGPT AI model on its network and devices, reports educational news site Chalkbeat. The move comes amid fears from educators that students will use ChatGPT to cheat on assignments, accidentally introduce inaccuracies in their work, or write essays in a way that will keep them from learning the material.

ChatGPT is a large language model created by OpenAI, and it is currently accessible for free through any web browser during its testing period. People can use it to write essays, poetry, and technical documents (or even simulate a Linux console) at a level that can often pass for human writing—although it can also produce very confident-sounding but inaccurate results.

Per Chalkbeat, NYC education department spokesperson Jenna Lyle said, “Due to concerns about negative impacts on student learning, and concerns regarding the safety and accuracy of content, access to ChatGPT is restricted on New York City Public Schools’ networks and devices. While the tool may be able to provide quick and easy answers to questions, it does not build critical-thinking and problem-solving skills, which are essential for academic and lifelong success.”

More than once this year, AI experts have repeated a familiar refrain: “Please slow down.” AI news in 2022 has been rapid-fire and relentless; the moment you knew where things currently stood in AI, a new paper or discovery would make that understanding obsolete.

In 2022, we arguably hit the knee of the curve when it came to generative AI that can produce creative works made up of text, images, audio, and video. This year, deep-learning AI emerged from a decade of research and began making its way into commercial applications, allowing millions of people to try out the tech for the first time. AI creations inspired wonder, created controversies, prompted existential crises, and turned heads.

Here’s a look back at the seven biggest AI news stories of the year. It was hard to choose only seven, but if we didn’t cut it off somewhere, we’d still be writing about this year’s events well into 2023 and beyond.

Throughout December, a social media user known as Stelfie the Time Traveller has been crafting a time-hopping travelogue using generative AI. Thanks to Stable Diffusion and fine-tuning, an anonymous artist has created a fictional photorealistic character that he can insert into faux historical photographs set in different eras, such as ancient Egypt or the time of the dinosaurs.

Stable Diffusion is a deep learning image synthesis model that allows people to create fictional scenes using text descriptions called prompts. With an additional technique called Dreambooth, people can insert their own subject or character into scenes generated by Stable Diffusion. It can also be used to insert real people into fictional situations.

So far, “Stelfie” has taken historical selfies during the ice age (being chased by a woolly mammoth), in ancient Egypt (during the construction of the pyramids), in ancient Greece (with the Trojan Horse), hanging out with Leonardo da Vinci (while creating the Mona Lisa), in the old West, while running from a tyrannosaurus rex, and while sailing with Christopher Columbus.

Recently, Adobe released a free AI-powered audio processing tool that can enhance some poor-quality voice recordings by removing background noise and making the voice sound stronger. When it works, the result sounds like a recording made in a professional sound booth with a high-quality microphone.

The new tool, called Enhance Speech, originated as part of an AI research project called Project Shasta. Recently, Adobe rebranded Project Shasta to Adobe Podcast.

Using Enhance Speech is free, but it requires creating an Adobe account and works best with a desktop web browser. Once registered, users can upload an MP3 or WAV file up to one hour long or 1GB in size. After several minutes, you can listen to the result in your browser or download the resulting cleaned-up audio.

On Wednesday, Stability AI announced it would allow artists to remove their work from the training dataset for an upcoming Stable Diffusion 3.0 release. The move comes as an artist advocacy group called Spawning tweeted that Stability AI would honor opt-out requests collected on its Have I Been Trained website. The details of how the plan will be implemented remain incomplete and unclear, however.

As a brief recap, Stable Diffusion, an AI image synthesis model, gained its ability to generate images by “learning” from a large dataset of images scraped from the Internet without consulting any rights holders for permission. Some artists are upset about it because Stable Diffusion generates images that can potentially rival human artists in an unlimited quantity. We’ve been following the ethical debate since Stable Diffusion’s public launch in August 2022.

To understand how the Stable Diffusion 3 opt-out system is supposed to work, we created an account on Have I Been Trained and uploaded an image of the Atari Pong arcade flyer (which we do not own). After the site’s search engine found matches in the Large-scale Artificial Intelligence Open Network (LAION) image database, we right-clicked several thumbnails individually and selected “Opt-Out This Image” in a pop-up menu.

On Tuesday, members of the online community ArtStation began widely protesting AI-generated artwork by placing “No AI Art” images in their portfolios. By Wednesday, the protest images dominated ArtStation’s trending page. The artists seek to criticize the presence of AI-generated work on ArtStation and to potentially disrupt future AI models trained using artwork found on the site.

Early rumblings of the protest began on December 5 when Bulgarian artist Alexander Nanitchkov tweeted, “Current AI ‘art’ is created on the backs of hundreds of thousands of artists and photographers who made billions of images and spend time, love and dedication to have their work soullessly stolen and used by selfish people for profit without the slightest concept of ethics.”

Nanitchkov also posted a stark logo featuring the letters “AI” in white uppercase behind the circular strike-through symbol. Below, a caption reads “NO TO AI GENERATED IMAGES.” This logo soon spread on ArtStation and became the basis of many protest images currently on the site.

On Wednesday, a designer and engineer named Arvind Sanjeev revealed his process for creating Ghostwriter, a one-of-a-kind repurposed Brother typewriter that uses AI to chat with a person typing on the keyboard. The “ghost” inside the machine comes from OpenAI’s GPT-3, a large language model that powers ChatGPT. The effect resembles a phantom conversing through the machine.

To create Ghostwriter, Sanjeev took apart an electric Brother AX-325 typewriter from the 1990s and reverse-engineered its keyboard signals, then fed them through an Arduino, a low-cost microcontroller that is popular with hobbyists. The Arduino then sends signals to a Raspberry Pi that acts as a network interface to OpenAI’s GPT-3 API.

When GPT-3 responds, Ghostwriter noisily types the AI model’s output onto paper automatically.

Over the past week, the smartphone app Lensa AI has become a popular topic on social media because it can generate stylized AI avatars based on selfie headshots that users upload. It’s arguably the first time personalized latent diffusion avatar generation has reached a mass audience.

While Lensa AI has proven popular among people on social media who like to share their AI portraits, the press has widely focused on the app’s reported tendency to sexualize depictions of women when Lensa’s AI avatar feature launched.

A product of Prisma Labs, Lensa launched in 2018 as a subscription app focused on AI-powered photo editing. In late November 2022, the app grew in popularity thanks to its new “Magic Avatar” feature. Lensa reportedly utilizes the Stable Diffusion image synthesis model under the hood, and Magic Avatar appears to use a personalization training method similar to Dreambooth (whose ramifications we recently covered). All of the training takes place off-device and in the cloud.

China’s Cyberspace Administration recently issued regulations prohibiting the creation of AI-generated media without clear labels, such as watermarks—among other policies—reports The Register. The new rules come as part of China’s evolving response to the generative AI trend that has swept the tech world in 2022, and they will take effect on January 10, 2023.

In China, the Cyberspace Administration oversees the regulation, oversight, and censorship of the Internet. Under the new regulations, the administration will keep a closer eye on what it calls “deep synthesis” technology.

In a news post on the website of China’s Office of the Central Cyberspace Affairs Commission, the government outlined its reasons for issuing the regulation. It pointed to the recent wave of text, image, voice, and video synthesis AI, which China recognizes as important to future economic growth (translation via Google Translate):

If you’re one of the billions of people who have posted pictures of themselves on social media over the past decade, it may be time to rethink that behavior. New AI image-generation technology allows anyone to save a handful of photos (or video frames) of you, then train AI to create realistic fake photos that show you doing embarrassing or illegal things. Not everyone may be at risk, but everyone should know about it.

Photographs have always been subject to falsifications—first in darkrooms with scissors and paste and then via Adobe Photoshop through pixels. But it took a great deal of skill to pull off convincingly. Today, creating convincing photorealistic fakes has become almost trivial.

Once an AI model learns how to render someone, their image becomes a software plaything. The AI can create images of them in infinite quantities. And the AI model can be shared, allowing other people to create images of that person as well.
