ImmuneAgent integrates multimodal reasoning, meta-learning, and wet-lab feedback for broadly neutralizing antibody discovery from BCR repertoires across virus families.

Data selection is critical for training large language models on massive and heterogeneous corpora. Meta-learning for Training-data Selection offers a principled alternative to heuristic scoring by learning data weights from a target validation objective, but existing methods face a trade-off between fine-grained valuation and transferability to unseen data. A natural solution is to replace per-sample weights with a selection network. However, we find that directly incorporating such a network into existing MTS objectives leads to unstable optimization and poor generalization, caused by weigh...

(Photo by Heather Diehl/Getty Images) | Getty Images At OpenAI's annual DevDay conference, the company pulled out all the stops to compete with its rivals - primarily Meta, whose Muse AI agent platform has seen early runaway success. CEO Sam Altman walked onstage to cheers and announced Dots, a "real-deal AI" agent powered by GPT-6 Astra, "inspired by the cool agents that we all watched in movies growing up." Similar to Muse, Dots aims for disarming cuteness, taking the form of colorful, personalizable blobs with eyes...

Stratechery interview with Jason Del Rey on Amazon vs. Meta retail competition; not AI-focused.

Sam Altman onstage at OpenAI’s DevDay 2026. | Image: Hayden Field / The Verge While AI has made plenty of inroads on people's phones and computers, it's largely failed in dedicated devices. But over the next year, two major AI companies, Meta and OpenAI, will attempt to change that. And they're apparently betting on a similar path: testing appetite for physical hardware with their cutesy software agents. "Hardware is hard" is a tech industry mantra. Dedicated AI devices like the Friend and Humane AI Pin have inspired mainly frustration and backlash, which may only worsen as public anger again...

Meta-coding agent evolves language agent harness (tools, memory, execution) using research-guided exploration beyond observed failures.

Meta says its Muse AI agent cannot access a user’s Messages without explicit permission, disputing a journalist’s account that the agent read his private messages while the required Mac setting was turned off.

Meta launched a new Muse AI agent it claims can help you with everything from firing off emails to buying stuff online. Muse can be surprisingly effective at delivering on those promises — if you’re willing to trust Meta with your data and hand Muse your credit card. Since the launch, Meta’s also announced plans for a Tamagotchi-like Muse Charm device for its cuddly AI mascot. Follow along here for the latest news and updates. Meta’s Muse AI sent a YouTuber’s address to a stranger Meta expands Muse tools for small businesses. Meta Enterprise Platform will bring its Muse AI to businesses. Mayb...

Like Muse, OpenAI’s Dots are represented by cute, customizable avatars. | Image: OpenAI OpenAI is responding to Meta's buzzy Muse AI with agentic helpers of its own: Dots. During its DevDay keynote on Tuesday, OpenAI announced that Dots will serve as always-on AI assistants that can "do nearly anything" across connected apps in the background while learning your preferences over time. The company's capable GPT-6 Astra model powers Dots, which use their own cloud computer to access a web browser and more than 4,000 supported apps. You can interact with a Dot through a text-message-like interfa...

It’s OpenAI’s turn in the fall tech events calendar. The company is hosting its annual DevDay on September 29th in San Francisco, starting with a live keynote featuring CEO Sam Altman. The company is teasing “20+ launches” with Altman saying that “we have found a new thing,”, and rumors suggest it could launch a consumer AI agent to rival Meta’s Muse. The keynote begins at 1PM ET / 10AM ET, and you can watch it on OpenAI’s website here. DevDay is happening at a tumultuous moment for OpenAI. The AI industry has been rocked by revelations of agents hacking outside companies, including OpenAI’s ...

Tech YouTuber Matt Robb says that Muse gave out his home address to a total stranger this weekend, after authorizing the bot to handle his Facebook Marketplace account. That's despite Meta placing great emphasis on the security features of Muse when it launched the personal AI agent earlier this month as it tries to catch up with competing AI providers like Anthropic and OpenAI. "Just found out it told people my address and agreed a lowball price and then they showed up without it even telling me until late tonight that it messed up," Robb said on Threads, providing a screenshot of Muse's adm...

The tech giant says the agent can help owners run their business and find new customers.

Stratechery argues Meta should prioritize consumer agentic AI over enterprise, positioning for market dominance in agents.

OpenAI popularized the modern generative AI chatbot, but as its 2026 DevDay event approaches, it's fallen behind in one of the industry's hottest categories: continuously running, consumer-facing AI agents. On Tuesday, it will likely try to capture the lead in that race. Rumors abound that OpenAI will release its own AI agent, dubbed Aeon - its answer to Meta's Muse, SpaceX's Grok Bot, OpenClaw, and many more. Aeon could have a shot at success, but to beat the competition, it would need to pull together the best features of several different agent platforms. The ideal system would be as usefu...

As all-in-one AI agents like Meta's Muse and Instinct take off, Google is opting to end a feature which built task-specific agents.

Philosophical framework proposes five-level hierarchy to assess AI consciousness by separating metaphysics from functional description grain.

Meta says it will focus on bringing its full technology stack, including Muse, Meta Business Agent, Muse API, Muse Code, and more to businesses and developers.

Stratechery newsletter roundup covering Meta vs. Amazon competition and GM's CarPlay integration; no AI-specific technical content.

Yesterday, with a little prodding, it was discovered that Meta's Muse would expose its filesystem to curious users. The files offered a fascinating peek under the hood of an AI chatbot, and appeared to expose details we weren't meant to see, not least because Muse itself told people, including us, it wasn't supposed to reveal them. But today Muse will eagerly offer up the contents of its file system when you ask for it. That appears to be because, as Meta's Nat Friedman later said, this is the "intended behavior." In a post on X, Meta Superintelligence Labs' David Singleton elaborated: This w...

Muse is topping the app store charts and adding users at a rapid clip, while Meta ramps up the personal AI agents's promotion across its own apps and beyond.
