Fides: agentic paper reproduction
An AI lab that reproduces published papers from their own equations and data. It freezes verifiable numeric targets before any code exists, re-implements the method, runs physics checks (gates), and issues a verdict it cannot write by hand. An adversarial critic then reviews every run. Runs on our own fleet models (GLM-5.3-Flash, DeepSeek-V4.1-Flash).
