Ehrlich is an AI-powered scientific discovery engine that automates the full hypothesis-driven research cycle. It uses a multi-model architecture where Opus 4.6 acts as a Director (formulating hypotheses, designing experiments, evaluating evidence), Sonnet 4.5 as parallel Researchers (executing 91 tools across 28 data sources), and Haiku 4.5 as a Summarizer (compressing outputs, grading evidence).
