Open-source, safety, and policy developments feature new Gemma 4 and Diffusion Gemma releases, a lab letter urging DNA/RNA screening laws, Amodei calling for an FAA-like AI regulator and third-party testing, research on agent harms and RL “societal hacking,” and a dispute over music-label settlements with Suno/Udio.
