About the Fellowship

Anthropic is working toward an “AI scientist”. This system would reason over long horizons and judge experiments like an expert. Today’s AI still falls short here, so the company invites experts to work with Claude. Fellows join small pods of researchers from related fields. First, they define the hardest open problems in their discipline. Then they build datasets and simulations to test Claude on those problems.

Machine learning experience helps but is optional. Scientific judgment and fast learning matter more. The first cohort included over 20 fellows. Their work now feeds Claude’s training and an internal science evaluation.

What Fellows Receive

• $100,000 to $167,000 for the four-month fellowship
• Weekly meetings with Anthropic researchers
• An ambitious, open-ended challenge scoped with the research team
• Access to frontier Claude models and internal evaluation tools
• Additional benefits, which the source does not detail

Who Can Apply

Applicants need the following:

• A STEM PhD and several years of experience, such as a postdoc or faculty role
• Daily hands-on experience with Claude and Claude Code
• Enthusiasm for AI reasoning about hard questions
• Comfort with fast-paced work and concrete results
• Existing U.S. work authorization for the whole program
• Anthropic cannot sponsor visas.

Required Materials

Later stages typically include a take-home exercise and research conversations. Check the official job posting for the application requirements.

How to Apply

Apply through the official Anthropic careers listing before the deadline. Offers follow by 20 November 2026. Fellows attend a one-week orientation in San Francisco. The role is a fixed-term contract through an employer of record, not direct employment.
