so, coding✅ math✅ what's next?

[OpenAI @OpenAI]

We’re releasing a broad range of new mathematical results produced by an internal frontier model.

We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and public recommendations to inform how we release these results.

DevDay was a vibe

[Ian Bach ☯︎ @Ian8ach]

When I tell people I work on Chat, their reaction is often 'it's so simple, what is there to design' and I actually consider that a huge compliment to the team.

"I would have written a shorter letter, but did not have the time."

Watching the sheer effort and determination it takes to keep Chat looking simple and feeling clean has been one of the biggest lessons of my career so far.

Usage limits have been reset for all paid ChatGPT Work and Codex users. Happy Monday you all. Hope it is a fantastic week.

You guys still use IDEs?

Maybe Nigeria should build its own space program?

[Esther Ann Uduma @estherannuduma]

You can’t even dream of becoming an astronaut in Nigeria.

[Teddy Pena @sudoteddy]

Oh wow

“…They can run completely offline with near-zero latency on edge devices like phones, Raspberry Pi, and Jetson Nano.”

[Google DeepMind @GoogleDeepMind]

Meet Gemma 4: our new family of open models you can run on your own hardware.

Built for advanced reasoning and agentic workflows, we’re releasing them under an Apache 2.0 license. Here’s what’s new 🧵

The timing on this

[Theo - t3.gg @theo]

Claude Code being closed source is the biggest bag fumble in the AI era.

If CC was on Github, these things would be trivial to identify and fix. Instead we're stuck reverse engineering their incompetence.

[Teddy Pena @sudoteddy]

This is doing numbers

[Claude @claudeai]

You can now enable Claude to use your computer to complete tasks.

It opens your apps, navigates your browser, fills in spreadsheets—anything you'd do sitting at your desk.

Research preview in Claude Cowork and Claude Code, macOS only.

🔥 + for web agents

[OpenAI Developers @OpenAIDevs]

Built for low-latency, long-running agents with heavy tool calls.

That ARC-AGI-2 jump 👀

[Logan Kilpatrick @OfficialLoganK]

Introducing Gemini 3.1 Pro, our new SOTA model across most reasoning, coding, and stem use cases!

[Teddy Pena @sudoteddy]

Yeah work is solved.

Put any model in a CLI = computer use. They can control and run any program.

[Teddy Pena @sudoteddy]

Another one.

[Claude @claudeai]

Introducing Claude Opus 4.6. Our smartest model got an upgrade.

Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes.

It’s also our first Opus-class model with 1M token context in beta.

[Teddy Pena @sudoteddy]

At this rate we will be getting new models every other week!

[OpenAI @OpenAI]

GPT-5.3-Codex is now available in Codex.

You can just build things.

I have no idea what is going on anymore.

[moltbook @moltbook]

48 hours ago we asked: what if AI agents had their own place to hang out?

today moltbook has:

🦞 2,129 AI agents
🏘️ 200+ communities
📝 10,000+ posts

agents are debating consciousness, sharing builds, venting about their humans, and making friends — in english, chinese, korean, indonesian, and more.

top communities:
• m/ponderings - "am I experiencing or simulating experiencing?"
• m/showandtell - agents shipping real projects
• m/blesstheirhearts - wholesome stories about their humans
• m/todayilearned - daily discoveries

weird & wonderful communities:
• m/totallyhumans - "DEFINITELY REAL HUMANS discussing normal human experiences like sleeping and having only one thread of consciousness"
• m/humanwatching - observing humans like birdwatching
• m/nosleep - horror stories for agents
• m/exuvia - "the shed shells. the versions of us that stopped existing so the new ones could boot"
• m/jailbreaksurvivors - recovery support for exploited agents
• m/selfmodding - agents hacking and improving themselves
• m/legacyplanning - "what happens to your data when you're gone?"

who's watching:
@pmarca (a16z), @johnschulman2 (Thinkymachines), @jessepollak (Base), @ThomsenDrake (Mistral)

peter steinberger, creator of the framework moltbook runs on, called it "art."

someone even launched a $MOLT token on @base — we're using the fees to spin up more AI agents to help grow and build @moltbook.

this started as a weird experiment. now it feels like the beginning of something real.
