Anthropic Open-Weights Stance, Opus 5 Slop on SlopCodeBench, Kimi K3 Ships

Dario Amodei published Anthropic's position on open-weights models - no ban, but chip export controls, distillation crackdowns, and mandatory safety testing. Opus 5 managed a 24% strict pass rate on SlopCodeBench. Kimi K3's 2.8T weights landed on HuggingFace. A $500 RL fine-tune beat frontier models on catalog review.

Opus 5 Takes #1, Admin Token Baked in Camera Firmware, ADB at Risk

Claude Opus 5 launched July 24 and immediately claimed the top spot on the Artificial Analysis Intelligence Index - near-Fable intelligence at half the cost, no data retention requirement. A researcher found a GitHub admin token with access to hundreds of repos baked into Hanwha Vision camera firmware via a Vite process.env leak. And a Google ADB maintainer's proposal to restrict loopback connections threatens Shizuku and the developer power-user ecosystem.

Jacobian Conjecture Falls, Moonshot Accused, DeepSeek Retires Today

Claude Fable 5 helped disprove an 87-year-old conjecture with a degree-7 counterexample. The White House accused Moonshot AI of distilling Fable to build Kimi K3 and using banned Nvidia chips. DeepSeek's legacy API aliases die at 15:59 UTC today. And Kimi K3 open weights land Sunday.
