When are we going to get AI agents managing experiments for us? Running large scale experiments always mess up my sleep🥲

We’re running another round of the Anthropic Fellows program. If you're an engineer or researcher with a strong coding or technical background, you can apply to receive funding, compute, and mentorship from Anthropic, beginning this October. There'll be around 32 places.

New Anthropic research: Persona vectors. Language models sometimes go haywire and slip into weird and unsettling personas. Why? In a new paper, we find “persona vectors"—neural activity patterns controlling traits like evil, sycophancy, or hallucination.

Just finished compiling eight papers into my PhD thesis with Claude’s help. I feel lucky compared to the many PhDs who graduated before me. I am also extremely jealous of the many PhDs who will graduate after me.

Today we're releasing Claude Opus 4.1, an upgrade to Claude Opus 4 on agentic tasks, real-world coding, and reasoning.

It’s interesting how much the sentiment around LLM shifts weekly. A few weeks ago everyone was all about how great IMO gold medals were. Last week was about how we are hitting diminishing returns. Back again this week, the models are winning IOI and by a significant margin. We

We launched a Claude Code learning mode! Claude Code not only makes you more productive, but can now also help you get better at coding. Whether you're a CS student or seasoned programmer, it will push you to think deeper about the code you're generating.

🧵 1/8 I’m building a world-class team of Research Program Managers at @ConstellationAI to advance AI safety! 🚀 Looking for experienced operators who can design and build the research ecosystem needed to safely navigate transformative AI. Application in thread!

🚀 Applications now open: Constellation's Astra Fellowship 🚀 We're relaunching Astra — a 3-6 month fellowship to accelerate AI safety research & careers. Alumni Eli Lifland & Romeo Dean co-authored AI 2027 and co-founded AI Futures Project with their Astra mentor Daniel Kokotajlo!

We’re hiring someone to run the Anthropic Fellows Program! Our research collaborations have led to some of our best safety research and hires. We’re looking for an exceptional ops generalist, TPM, or research/eng manager to help us significantly scale and improve our collabs 🧵

What happens when AI is guided by law-like principles? Can we design some computational tools to "debug" rules? Check out our new work 📝 𝕊𝕥𝕒𝕥𝕦𝕥𝕠𝕣𝕪 ℂ𝕠𝕟𝕤𝕥𝕣𝕦𝕔𝕥𝕚𝕠𝕟 𝕒𝕟𝕕 𝕀𝕟𝕥𝕖𝕣𝕡𝕣𝕖𝕥𝕒𝕥𝕚𝕠𝕟 𝕗𝕠𝕣 𝔸𝕀🧑‍⚖️ to find out more! 🧵(1/10)

Today Thinking Machines Lab is launching our research blog, Connectionism. Our first blog post is “Defeating Nondeterminism in LLM Inference” We believe that science is better when shared. Connectionism will cover topics as varied as our research is: from kernel numerics to

It was amazing to be a core contributor to this Gold-winning ICPC effort. First the IMO, and two months later ICPC! The reasoning capabilities of foundation models continue to grow at breakneck speed and I can't wait to see what they do next.

Sharing our initial leaderboard and open data release for 🎶Music Arena⚔️! Music is subjective and multi-dimensional. A key goal of Music Arena is to provide insights beyond binary preferences! 🧵

Tinker provides an abstraction layer that is the right one for post-training R&D -- it's the infrastructure I've always wanted. I'm excited to see what people build with it. "Civilization advances by extending the number of important operations which we can perform without
