Science \ Anthropic

The scientific and discovery process consists of feedback loops: designing and conducting an experiment, interpreting the results, revising the question, and beginning again. We’re working to tighten these loops by developing tools that make researchers more efficient or help them develop entirely new approaches, and by building training environments and evaluations that help us improve Claude’s performance on scientific tasks.
We work with universities, research institutes, biotech companies, and academic medical centers—through direct API access, co-developed custom agents, applied AI technical support, and more—to get Claude into the hands of scientists. This allows us to incorporate feedback based on real-world evaluation and applied research across domains, demonstrating the tangible impacts AI is having on science.
We’re sharing another finding from Anthropic’s biology research lab: the first 3D structure of a vault particle found in prokaryotic cells. Here, we describe how Claude helped at each step of this research.
We asked an internal research Claude model to design minibinders (small proteins that attach tightly to a target) against scorpion neurotoxins.
Guest author Prof. Matthew Schwartz describes what happened when he stopped fighting Claude and allowed Claude to find “Claude-shaped” problems: ones best suited to the capabilities of the current generation of LLM tools. This led him to build BootLoops, a toolkit for exact calculations in quantitative science, which he has been applying across scientific fields alongside experts.
We are sharing the first complete computer-checked proof of Fermat’s Last Theorem. Claude worked largely autonomously over 11 days to write the proof in the Lean programming language.
Works to understand the risks of AI models and develop ways to ensure future ones remain helpful, honest, and harmless.
Studies and monitors the impact of AI systems on individuals, firms, and economies.
Builds the infrastructure and systems that make Claude reliable and trustworthy.
Stress-tests AI systems to understand the full extent of their current capabilities and anticipate what comes next.
Studies how large language models work internally as a foundation for AI safety.
Studies how AI affects people, both individually and collectively.
Explores how AI can increase the pace of scientific progress through both research and collaborations.
