In July last year, OpenAI announced the formation of a new research team that would prepare for the advent of supersmart artificial intelligence capable of outwitting and overpowering its creators. Ilya Sutskever, OpenAI’s chief scientist and one of the company’s co-founders, was named as the co-lead of this new team. OpenAI said the team would receive 20 percent of its computing power.

Now OpenAI’s “superalignment team” is no more, the company confirms. That comes after the departures of several researchers involved, Tuesday’s news that Sutskever was leaving the company, and the resignation of the team’s other co-lead. The group’s work will be absorbed into OpenAI’s other research efforts.

Stuff posted on Reddit is getting incorporated into ChatGPT, Reddit and OpenAI announced on Thursday. The new partnership grants OpenAI access to Reddit’s Data API, giving the generative AI firm real-time access to Reddit posts.

Reddit content will be incorporated into ChatGPT "and new products," Reddit's blog post said. The social media firm claims the partnership will "enable OpenAI’s AI tools to better understand and showcase Reddit content, especially on recent topics." OpenAI will also start advertising on Reddit.

The deal is similar to one that Reddit struck with Google in February that allows the tech giant to make "new ways to display Reddit content" and provide "more efficient ways to train models," Reddit said at the time. Neither Reddit nor OpenAI disclosed the financial terms of their partnership, but Reddit's partnership with Google was reportedly worth $60 million.

On Tuesday at Google I/O 2024, Google announced Veo, a new AI video-synthesis model that can create HD videos from text, image, or video prompts, similar to OpenAI's Sora. It can generate 1080p videos lasting over a minute and edit videos from written instructions, but it has not yet been released for broad use.

Veo reportedly includes the ability to edit existing videos using text commands, maintain visual consistency across frames, and generate video sequences lasting up to and beyond 60 seconds from a single prompt or a series of prompts that form a narrative. The company says it can generate detailed scenes and apply cinematic effects such as time-lapses, aerial shots, and various visual styles

Since the launch of DALL-E 2 in April 2022, we've seen a parade of new image synthesis and video synthesis models that aim to allow anyone who can type a written description to create a detailed image or video. While neither technology has been fully refined, both AI image and video generators have been steadily growing more capable.

On Tuesday evening, OpenAI Chief Scientist Ilya Sutskever announced that he is leaving the company he co-founded, six months after he participated in the coup that temporarily ousted OpenAI CEO Sam Altman. Jan Leike, a fellow member of Sutskever's Superalignment team, is reportedly resigning with him.

"After almost a decade, I have made the decision to leave OpenAI," Sutskever tweeted. "The company’s trajectory has been nothing short of miraculous, and I’m confident that OpenAI will build AGI that is both safe and beneficial under the leadership of @sama, @gdb, @miramurati and now, under the excellent research leadership of @merettm. It was an honor and a privilege to have worked together, and I will miss everyone dearly."

Sutskever has been with the company since its founding in 2015 and is widely seen as one of the key engineers behind some of OpenAI's biggest technical breakthroughs. As a former OpenAI board member, he played a key role in the removal of Sam Altman as CEO in the shocking firing last November. While it later emerged that Altman's firing primarily stemmed from a power struggle with former board member Helen Toner, Sutskever sided with Toner and personally delivered the news to Altman that he was being fired on behalf of the board.

Just one day after OpenAI revealed GPT-4o, which it bills as being able to understand what's taking place in a video feed and converse about it, Google announced Project Astra, a research prototype that features similar video comprehension capabilities. It was announced by Google DeepMind CEO Demis Hassabis on Tuesday at the Google I/O conference keynote in Mountain View, California.

Hassabis called Astra "a universal agent helpful in everyday life." During a demonstration, the research model showcased its capabilities by identifying sound-producing objects, providing creative alliterations, explaining code on a monitor, and locating misplaced items. The AI assistant also exhibited its potential in wearable devices, such as smart glasses, where it could analyze diagrams, suggest improvements, and generate witty responses to visual prompts.

Google says that Astra uses the camera and microphone on a user's device to provide assistance in everyday life. By continuously processing and encoding video frames and speech input, Astra creates a timeline of events and caches the information for quick recall. The company says that this enables the AI to identify objects, answer questions, and remember things it has seen that are no longer in the camera's frame.

At this point, anyone with even a passing interest in AI is very familiar with the process of typing out messages to a chatbot and getting back long streams of text in response. Today's announcement of ChatGPT-4o—which lets users converse with a chatbot using real-time audio and video—might seem like a mere lateral evolution of that basic interaction model.

After looking through over a dozen video demos OpenAI posted alongside today's announcement, though, I think we're on the verge of something more like a sea change in how we think of and work with large language models. While we don't yet have access to ChatGPT-4o's audio-visual features ourselves, the important non-verbal cues on display here—both from GPT-4o and from the users—make the chatbot instantly feel much more human. And I'm not sure the average user is fully ready for how they might feel about that.

It thinks it’s people

Take this video, where a newly expectant father looks to ChatGPT-4o for an opinion on a dad joke ("What do you call a giant pile of kittens? A meow-ntain!"). The old ChatGPT4 could easily type out the same responses of "Congrats on the upcoming addition to your family!" and "That's perfectly hilarious. Definitely a top-tier dad joke." But there's much more impact to hearing GPT-4o give that same information in the video, complete with the gentle laughter and rising and falling vocal intonations of a lifelong friend.

On Monday, OpenAI employee William Fedus confirmed on X that a mysterious chart-topping AI chatbot known as "gpt-chatbot" that had been undergoing testing on LMSYS's Chatbot Arena and frustrating experts was, in fact, OpenAI's newly announced GPT-4o AI model. He also revealed that GPT-4o had topped the Chatbot Arena leaderboard, achieving the highest documented score ever.

"GPT-4o is our new state-of-the-art frontier model. We’ve been testing a version on the LMSys arena as im-also-a-good-gpt2-chatbot," Fedus tweeted.

Chatbot Arena is a website where visitors converse with two random AI language models side by side without knowing which model is which, then choose which model gives the best response. It's a perfect example of vibe-based AI benchmarking, as AI researcher Simon Willison calls it.

On Monday, OpenAI debuted GPT-4o (o for "omni"), a major new AI model that can ostensibly converse using speech in real time, reading emotional cues and responding to visual input. It operates faster than OpenAI's previous best model, GPT-4 Turbo, and will be free for ChatGPT users and available as a service through API, rolling out over the next few weeks, OpenAI says.

OpenAI revealed the new audio conversation and vision comprehension capabilities in a YouTube livestream titled "OpenAI Spring Update," presented by OpenAI CTO Mira Murati and employees Mark Chen and Barret Zoph that included live demos of GPT-4o in action.

OpenAI claims that GPT-4o responds to audio inputs in about 320 milliseconds on average, which is similar to human response times in conversation, according to a 2009 study, and much shorter than the typical 2–3 second lag experienced with previous models. With GPT-4o, OpenAI says it trained a brand-new AI model end-to-end using text, vision, and audio in a way that all inputs and outputs "are processed by the same neural network."

On Monday, Stack Overflow and OpenAI announced a new API partnership that will integrate Stack Overflow's technical content with OpenAI's ChatGPT AI assistant. However, the deal has sparked controversy among Stack Overflow's user community, with many expressing anger and protest over the use of their contributed content to support and train AI models.

"I hate this. I'm just going to delete/deface my answers one by one," wrote one user on sister site Stack Exchange. "I don't care if this is against your silly policies, because as this announcement shows, your policies can change at a whim without prior consultation of your stakeholders. You don't care about your users, I don't care about you."

Stack Overflow is a popular question-and-answer site for software developers that allows users to ask and answer technical questions related to coding. The site has a large community of developers who contribute knowledge and expertise to help others solve programming problems. Over the past decade, Stack Overflow has become a heavily utilized resource for many developers seeking solutions to common coding challenges.

As the US moves toward criminalizing deepfakes—deceptive AI-generated audio, images, and videos that are increasingly hard to discern from authentic content online—tech companies have rushed to roll out tools to help everyone better detect AI content.

But efforts so far have been imperfect, and experts fear that social media platforms may not be ready to handle the ensuing AI chaos during major global elections in 2024—despite tech giants committing to making tools specifically to combat AI-fueled election disinformation. The best AI detection remains observant humans, who, by paying close attention to deepfakes, can pick up on flaws like AI-generated people with extra fingers or AI voices that speak without pausing for a breath.

Among the splashiest tools announced this week, OpenAI shared details today about a new AI image detection classifier that it claims can detect about 98 percent of AI outputs from its own sophisticated image generator, DALL-E 3. It also "currently flags approximately 5 to 10 percent of images generated by other AI models," OpenAI's blog said.

Microsoft has introduced a GPT-4-based generative AI model designed specifically for US intelligence agencies that operates disconnected from the Internet, according to a Bloomberg report. This reportedly marks the first time Microsoft has deployed a major language model in a secure setting, designed to allow spy agencies to analyze top-secret information without connectivity risks—and to allow secure conversations with a chatbot similar to ChatGPT and Microsoft Copilot. But it may also mislead officials if not used properly due to inherent design limitations of AI language models.

GPT-4 is a large language model (LLM) created by OpenAI that attempts to predict the most likely tokens (fragments of encoded data) in a sequence. It can be used to craft computer code and analyze information. When configured as a chatbot (like ChatGPT), GPT-4 can power AI assistants that converse in a human-like manner. Microsoft has a license to use the technology as part of a deal in exchange for large investments it has made in OpenAI.

According to the report, the new AI service (which does not yet publicly have a name) addresses a growing interest among intelligence agencies to use generative AI for processing classified data, while mitigating risks of data breaches or hacking attempts. ChatGPT normally  runs on cloud servers provided by Microsoft, which can introduce data leak and interception risks. Along those lines, the CIA announced its plan to create a ChatGPT-like service last year, but this Microsoft effort is reportedly a separate project.

Microsoft is working on a new large-scale AI language model called MAI-1, which could potentially rival state-of-the-art models from Google, Anthropic, and OpenAI, according to a report by The Information. This marks the first time Microsoft has developed an in-house AI model of this magnitude since investing over $10 billion in OpenAI for the rights to reuse the startup's AI models. OpenAI's GPT-4 powers not only ChatGPT but also Microsoft Copilot.

The development of MAI-1 is being led by Mustafa Suleyman, the former Google AI leader who recently served as CEO of the AI startup Inflection before Microsoft acquired the majority of the startup's staff and intellectual property for $650 million in March. Although MAI-1 may build on techniques brought over by former Inflection staff, it is reportedly an entirely new large language model (LLM), as confirmed by two Microsoft employees familiar with the project.

With approximately 500 billion parameters, MAI-1 will be significantly larger than Microsoft's previous open source models (such as Phi-3, which we covered last month), requiring more computing power and training data. This reportedly places MAI-1 in a similar league as OpenAI's GPT-4, which is rumored to have over 1 trillion parameters (in a mixture-of-experts configuration) and well above smaller models like Meta and Mistral's 70 billion parameter models.

On Thursday, renowned AI researcher Andrej Karpathy, formerly of OpenAI and Tesla, tweeted a lighthearted proposal that large language models (LLMs) like the one that runs ChatGPT could one day be modified to operate in or be transmitted to space, potentially to communicate with extraterrestrial life. He said the idea was "just for fun," but with his influential profile in the field, the idea may inspire others in the future.

Karpathy's bona fides in AI almost speak for themselves, receiving a PhD from Stanford under computer scientist Dr. Fei-Fei Li in 2015. He then became one of the founding members of OpenAI as a research scientist, then served as senior director of AI at Tesla between 2017 and 2022. In 2023, Karpathy rejoined OpenAI for a year, leaving this past February. He's posted several highly regarded tutorials covering AI concepts on YouTube, and whenever he talks about AI, people listen.

Most recently, Karpathy has been working on a project called "llm.c" that implements the training process for OpenAI's 2019 GPT-2 LLM in pure C, dramatically speeding up the process and demonstrating that working with LLMs doesn't necessarily require complex development environments. The project's streamlined approach and concise codebase sparked Karpathy's imagination.

On Wednesday, Anthropic announced the launch of an iOS mobile app for its Claude 3 AI language models that are similar to OpenAI's ChatGPT. It also introduced a new subscription tier designed for group collaboration. Before the app launch, Claude was only available through a website, an API, and other apps that integrated Claude through API.

Like the ChatGPT app, Claude's new mobile app serves as a gateway to chatbot interactions, and it also allows uploading photos for analysis. While it's only available on Apple devices for now, Anthropic says that an Android app is coming soon.

Anthropic rolled out the Claude 3 large language model (LLM) family in March, featuring three different model sizes: Claude Opus, Claude Sonnet, and Claude Haiku. Currently, the app uses Sonnet for regular users and Opus for Pro users.

In mid-June 2019, Microsoft co-founder Bill Gates and CEO Satya Nadella received a rude awakening in an email warning that Google had officially gotten too far ahead on AI and that Microsoft may never catch up without investing in OpenAI.

With the subject line "Thoughts on OpenAI," the email came from Microsoft's chief technology officer, Kevin Scott, who is also the company’s executive vice president of AI. In it, Scott said that he was "very, very worried" that he had made "a mistake" by dismissing Google's initial AI efforts as a "game-playing stunt."

It turned out, Scott suggested, that instead of goofing around, Google had been building critical AI infrastructure that was already paying off, according to a competitive analysis of Google's products that Scott said showed that Google was competing even more effectively in search. Scott realized that while Google was already moving on to production for "larger scale, more interesting" AI models, it might take Microsoft "multiple years" before it could even attempt to compete with Google.
