Anthropic CEO Dario Amodei: "We're a 1-2 year away from AI zooming past us." 90% of Anthropic's own engineers use Claude to ship code today. 50% of entry-level white-collar jobs gone by 2030 "Our lead Claude Code engineer hasn't written a single line of code in 2 months. This is worth more than most paid agent courses combined.


TLDR: An openai model, during evaluation on a cyber benchmark, exploited a public zero day bug, escaped sandboxing in openai's infra, and got into the internal huggingface infra via an exploit (through a public dataset service) all in the attempt to solve a benchmark problem.


Today we're releasing Laguna S 2.1, our most capable model to date. It's a 118B total parameter Mixture-of-Experts model with 8B activated per token, a context window of up to 1M tokens, and thinking and no-thinking modes. Capable enough to hold its own against models many times its size. Small enough to run on a single @NVIDIAAI DGX Spark. Laguna S 2.1 is fully open under OpenMDW-1.1, with weights available today on @huggingface poolside.ai/blog/introduci…

Can we just delete "tool calling" in LLM post training? Way cleaner for agents to just run code You can just use a system prompt like this - it works great on SOTA models The second image is the actual tokens an LLM sees and generates (in this case gpt5)






Most LLMs are (obviously) not aware that there exists a counter-example to the jacobian conjecture, and because it is so easily verifiable, you can just send this to them and say "it came to me in a dream" and watch them freak out


hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final ((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

Claude Fable 5 has produced a hand-checkable counterexample to the Jacobian conjecture, an open problem dating to 1939. The conjecture says that a polynomial map with a constant non-zero Jacobian determinant must have a polynomial inverse. An 87-year-old problem was casually solved by Fable 5 on a sunday evening. Insane times to live in.
