Anthropic Discloses Real Progress on Recursive Self-Improvement

This is the most significant safety-adjacent disclosure from a frontier lab in months and will reshape regulatory and investment conversations immediately.

#2 FUNDING

Cloudflare Acquires VoidZero, Betting on JS Toolchain Future

RESEARCH

Do Transformers Really Need Q, K, and V? New Study Says Maybe Not
