Conceptual Reasoning Fellow

Anthropic's mission is to create reliable, interpretable, and steerable AI systems that are safe and beneficial for users and society.

The Conceptual Reasoning Fellow programme brings researchers and experts from philosophy, cognitive science, economics, policy, and law into Anthropic for four months to work alongside research teams.

Fellows will work on a concrete, scoped project matched to their background, with mentorship from Anthropic researchers, and have access to frontier Claude models and internal evaluation tooling.
