Google DeepMind released Genie 4, a world model that generates photorealistic interactive scenes in real time, with sound, speech and people who move and react.
In an Anthropic experiment, 50 professional analysts sided with a lean secretly assigned to their AI agent on 86% of analytical choices.
Axiom says it has formalised the whole classification of finite simple groups in Lean, and the Federal Reserve announces its rate decision on Wednesday.
The new world model generates photorealistic scenes that can be explored with a keyboard and steered with text as they run, with native sound and dialogue. It is available as a research preview to trusted testers.

The 10-year yield was 3.97% on 27 February, before the war with Iran turned hot again. It peaked at 5.31% on 5 October and stood at 5.00% on 26 October, the day before the Federal Open Market Committee began its two-day meeting.
In an Anthropic randomised trial, 50 analysts working with Claude Code matched a coin-flip lean given to the agent on 86% of four analytical decisions, against 50% if the lean had no effect.
