The Brief

Today's AI news is dominated by safety reckonings at the top labs and a scrappy open-source model punching way above its weight.

OpenAI is deliberately slowing development of its most capable models after concluding its upcoming 'Astra' system may be nearing dangerous cyberattack capabilities, and it launched a dedicated ChatGPT for Teens with stronger parental controls. Anthropic's CEO sparked a public fight over whether AI power inevitably centralizes even with open models, while regulators are separately probing venture firm Andreessen Horowitz over board conflicts at rival AI data companies. On the product side, Cursor launched its own GitHub rival right as GitHub suffered a major outage, and a scrappy 27-billion-parameter open model from Alibaba, Qwen3.8-27B, is turning heads by matching much larger models on coding and reasoning benchmarks while running on ordinary hardware. Meanwhile, Modular open-sourced its Mojo programming language and researchers pushed the theoretical limits of matrix multiplication using Google's AlphaEvolve system.

Anthropic CEO Says AI Naturally Centralizes Power, Even With Open Models

Amid a public spat on X with investors and a Meta researcher, Anthropic's Dario Amodei argues that open-weight models don't democratize AI—they just shift power to whoever controls the most computing hardware—while critics accuse him of using fear to win regulatory advantage.
