Illuminating the frontier
Anthropic is sharing new measurements that would give the public visibility into frontier AI development. Builds the infrastructure and systems that make Claude reliable and trustworthy. Oct 20, 2026 How Claude designed protein binders against scorpion neurotoxins We asked an internal research Claude model to design minibinders (small proteins that attach tightly to a target) against scorpion neurotoxins. Oct 8, 2026 The missing map of the sky Brice Ménard, an astrophysicist at Johns Hopkins University and a researcher at Anthropic, explains how he worked with Claude Science to produce the first complete map of the sky in UV light.
