Anthropic publishes three internal measures of AI development
The company says it will track how much of its own research is done by AI, how well agents are overseen, and how compute is allocated.
Claude optimised inference for thirty open biology models, Anthropic says
The company reports a fourfold speed-up and is funding a protein design competition to test more than five thousand designs experimentally.
