AI model
Claude Fable is a family of Anthropic AI language models, used for coding and reasoning tasks and sold to enterprises, competing with OpenAI's GPT-6 line.
Chris Dzoba had two AI models design a search that found a simple, rotationally symmetric 17-set Venn diagram, the next size after 2014's 13-set one. A result like this can be confirmed by counting, yet so far its only reported check is one mathematician zooming in by eye.

Scientific American's account from the mathematicians' congress in Philadelphia has a Fields medalist quitting for OpenAI and a Millennium Prize problem falling to an opaque mix of models, with no verification trail reported for either.

Anthropic says a consultant in Bamako used Claude to engineer a monitoring system scoped to roughly 25 million SIM cards across Mali's three mobile operators. Because the platform ran on other models, it kept running after the ban.

Anthropic's third misuse report says its 2025 Claude models sat well below the level that could help a sophisticated user with dangerous biology, and that for current models it can no longer make that assurance.

RoboCurve scored 19 successes in 20 physical attempts on a pair of I2RT YAM arms, at roughly 2.1k output tokens a run. The humanoid pickup described in the same account happened in a simulator.

Reuters says the deliberation includes a safety review of the model itself and a judgment about profitability, and it comes days after Dario Amodei asked the industry to slow down building more capable systems.

Anil Madhavapeddy patched a path traversal bug in OCaml's cohttp and found probes for it in his logs ten minutes after opening the fix PR. His own agent had already built the exploit from a bug-class hint.

Gartner puts this year's AI spending at $2.59 trillion, but the software and services layer the labs actually compete for is barely $1 trillion of it, which is what the compressed release calendar is defending.
