👋Hy4 is here, new with vision. Firmly among the leading open models. More productive everywhere: finance, frontend, game, officework, research… Built responsibly, with cyber/biosecurity in mind. Try it out and let us know! 🔗:
Today we’re announcing that OpenAI will acquire @pierrecomputer to accelerate our vision for making Codex a place where teams can build software together with AI, from first idea to the version they ship. Pierre’s open-source developer tools already power parts of Codex today. Together, we’ll build on that foundation for the agentic era.
ORACLE CANCELS $7B CHIP LEASING DEAL WITH TENCENT: FT things starting to move
Today we release Ripple-65B Preview, our 65B dense LLM we pretrained from scratch. Ripple sets a new state-of-the-art for U.S. open-weight models in agentic coding tasks, surpassing significantly larger models including Muse Spark Open-816B, Beam-501B, Inkling-975B, and Nemotron 3 Ultra-550B.

GOLDMAN SACHS: DEMOCRATIC WINS COULD THREATEN 45% OF US DATA CENTER EXPANSION Goldman Sachs warns that Democratic victories at state and local levels could trigger temporary data-center construction moratoria. 🔸 45% of planned US data-center capacity could be affected. 🔸 Texas alone accounts for roughly 25% of planned capacity. 🔸 Texas, Georgia and Michigan could introduce restrictions on tax breaks, electricity, water and environmental permits. However, Goldman expects any moratoria to be short-lived, with political pressure easing over time.
Can LLMs simulate biology? We tested frontier models on real lab experiments: predict how cells respond to drugs, gene knockdowns, and immune signals. Even the best get only part of the response right. Lots of room to improve. Introducing BioSimBench, built on @NVIDIAAI. 🧵
I am very excited to share that Conductor is joining Meta! We have some big, crazy plans for the next interface. If you liked Conductor, you’re gonna love what’s coming. We’re super excited to work with @natfriedman and @alexandr_wang at MSL to build it. They’ve been on an absolute tear, and I’m convinced MSL has the highest talent density of all the labs. A huge thank you to our earliest believers @aaron_epstein, @ilyasu, and @nabeel. And to everyone here who tried Conductor, sent us feedback, and prompt requests - you made this so much fun. Thank you ❤️🚂 Choo choo!
Background subagents in Claude Code now use less of your usage limit. A running subagent updates its status line every 30 seconds, and each update used to re-read its whole conversation. Now Haiku 5.5 writes it from short notes instead, so each update costs about 99% less.
An update on building games with Claude Code: Last week some of you ran into Claude Code pushing back on game projects it should have just built. We'd added a short rule to the Opus 5.5 prompt to steer Claude away from recreating specific existing games, but it was also kicking in when you referenced one just to describe the mechanics you wanted. We've updated that rule in 2.1.317. You can name a game to describe what you want and Claude should now build an original game in that genre. If you ask for a copy of the original, it'll offer to build something similar instead. We want Claude to be as helpful as possible when you're building something original, but also to protect your work if someone else tries to copy it. We'll keep improving this, so let us know if Claude turns down work that's yours. Thanks to everyone who shared feedback!
Voice Remixing for Gemini 3.8 Flash TTS is now live in @GoogleAIStudio and the Gemini API. Start with a preset from our library of 2,000+ voices or a custom-designed voice, and use prompts to fine-tune timbre, pitch, pace, and accent, like "add a subtle Southern U.S. accent" or "make it sound like a fire-breathing dragon." 🐉
We decoupled memory from the model. Living Brain is one persistent brain for ChatGPT, Claude, Cursor, Codex and your own agents. Write in one, retrieve in any. 92.2% on LoCoMo. 464ms median retrieval. Up to 22.6x fewer tokens per question. LLMs have parameters. Living Brain has plasticity.
This is incredibly bad news. Abdul El-Sayed wants to pause AI, while at the same time, almost every AI data center is being blocked by local communities. Folks fail to realize just how transformative AI is for humanity. It’s a shame.
Today we’re introducing Aether @aetherruntime. The fastest cloud coding agents in the world that you can use with your existing subscription Give it a task and just 20 seconds later your build is running on its own cloud machine. You can pick up from your phone, watch every line, and step in whenever you want as if it was local. Close the laptop. It keeps going. It runs Claude Code or Codex on the Claude or ChatGPT plan you already pay for so there’s not a 2nd AI bill. You only pay for the machine. When it’s done, if code review is enabled, a reviewer agent runs the code with the changes, which catches classes of bugs that can't be found from static analysis. Before building Aether I built infra at Apple, Uber, and HeyGen. I built Aether because the cloud agents I tried before all had drawbacks, and I couldn't imagine building something without it now. It’s free to start.

Today was my last day at Anthropic. I am so thankful for the time I got to spend there. I couldn't be more thankful for the time I spent and the connections I made. Will be taking some time off as I prepare for my next thing. I'll share more soon :)
some fun slides from my upcoming talk @aiDotEngineer very excited to share how we ship crazy amounts of code (30x'd) without reading it, yet perf is as good if not better then when we launched there's a lot more to improve of course, and the ceiling is far from being reached, but given the relentless shipping speed and our high bar for polish, i think that our agent friendly architecture bets are paying off at taming the slop fun fact: ~230 people landed at least 1 PR to grok bot in october!

Data centers in space looking pretty appealing right now
🚨 “50% of all entry-level lawyers, consultants, and finance professionals will be completely wiped out within the next 5 years.” - Anthropic founder Dario Amodei.
Your feedback is on its way to Adam.
That was everything from Wednesday, November 4. The next deck lands tomorrow.
