# Feynman — The Open Source AI Research Agent
> A research-first CLI agent that searches papers, synthesizes evidence, replicates experiments, and delivers source-grounded research briefs.
Feynman is an open source AI research agent that runs in your terminal. Point it at a research question and it searches academic papers, crawls the web, dispatches parallel subagents, verifies citations, and delivers structured research briefs with inline sources — all from a single command.
Install Feynman on macOS, Linux, or Windows in one command.
Run your first deep research session in under five minutes.
Explore deep research, literature review, replication, audit, and more.
Full reference for every command, flag, and slash workflow.
## What Feynman does
```bash theme={null}
# Ask a research question naturally
feynman "what do we know about scaling laws in LLMs?"
# Run a source-heavy multi-agent investigation
feynman deepresearch "mechanistic interpretability"
# Literature review from primary sources
feynman lit "RLHF alternatives"
# Compare a paper's claims against its public codebase
feynman audit 2401.12345
# Replicate an experiment on local or cloud GPUs
feynman replicate "chain-of-thought improves math"
```
## How it works
Feynman orchestrates four specialized subagents — **Researcher**, **Writer**, **Reviewer**, and **Verifier** — over a pool of tools: AlphaXiv for paper search and Q\&A, web search for current information, Docker and cloud GPU compute for experiment execution, and session memory for recall across sessions. Every output links claims to papers, docs, or repositories with direct URLs.
Run the one-line installer. Feynman ships as a standalone bundle with no external runtime dependencies.
```bash theme={null}
curl -fsSL https://feynman.is/install | bash
```
Run `feynman setup` to pick a model provider and authenticate. Feynman supports Anthropic, OpenAI, Google, OpenRouter, and more.
```bash theme={null}
feynman setup
```
Launch the interactive REPL or pass a question directly. Use slash commands to invoke specific research workflows.
```bash theme={null}
feynman
> /deepresearch transformer architectures for protein folding
```
## Key capabilities
Multi-agent investigation with parallel researchers, synthesis, and a verification pass. Produces a cited brief saved to `outputs/`.
Structured review from paper search and primary sources, with consensus, disagreements, and open questions.
Replicate paper results locally, in Docker, or on Modal / RunPod GPU infrastructure.
Compares a paper's claims against the public codebase to surface mismatches.
Severity-graded feedback on drafts or papers, with a concrete revision plan.
Search, read, Q\&A, and annotate academic papers via the `alpha` CLI.
