Feynman: Open Source Research Agent with Paper-Codebase Audit Tool
What Feynman Does
Feynman is an open source research agent CLI that handles research questions through a multi-agent architecture. When you ask a research question, it dispatches four subagents in parallel:
- Researcher: Searches papers and web
- Reviewer: Runs simulated peer review with severity grading
- Writer: Produces structured output
- Verifier: Checks every citation and kills dead links
Key Features from Source
The standout feature mentioned in the source is the audit tool: Feynman audit [arxiv-id] pulls a paper's claims and compares them against the actual public codebase. This addresses the common problem of wondering whether published code actually implements what's claimed in the paper.
Other capabilities include:
- Experiment replication on local or cloud GPUs via modal/runpod
- Literature reviews showing consensus vs disagreements vs open questions
- Deep research mode with multi-agent parallel investigation
- Option to install just the research skills into Claude Code or Codex without the full terminal app
Technical Details
- One command installation
- MIT license
- Built on pi for the agent runtime
- Uses alphaxiv for paper search
- 2.3k stars on GitHub at time of source publication
- Launch tweet received 2,768 bookmarks from an account with 1,400 followers
The architecture specifically addresses hallucination issues common in AI research tools by dedicating an entire agent to catching incorrect citations before they reach the user.
