Feynman
The open source AI research agent that reads papers, searches the web, and writes research drafts.
Quick Answer
AIFeynman is an open-source AI research agent for automating scientific investigation. It can search literature databases, inspect Hugging Face Hub, perform web research, and parse local documents. Best for researchers and scientists automating literature reviews and ML engineers seeking ranked training recipes. Open-source.
Feynman is an open-source AI research agent that automates scientific investigation, experiment planning, and literature reviews. It can search literature databases, inspect Hugging Face Hub, perform web research, and parse local documents. Feynman is self-hosted and supports various LLM backends via API keys.
Feynman offers a unique set of research workflows like /deepresearch for plan-first investigation, /lit for literature review with consensus mapping, and /autoresearch for bounded hypothesize-experiment-measure loops. It integrates directly with scientific databases like Semantic Scholar and arXiv.
