The honest brief
Chai Discovery
One of the few drug-discovery shops to ship open model weights plus a free in-browser server, rather than locking everything behind pharma partnerships.
- Free in-browser structure prediction
- Open Chai-1 weights
- SOTA protein-ligand accuracy
- OpenAI-backed
- Weights non-commercial only
- Chai-2 not open
- Young company (2024)
- Core IP still proprietary
Insilico Medicine
Sells its full discovery pipeline as licensed software — pharma can run PandaOmics and Chemistry42 directly, not just via a partner-only program.
- End-to-end Pharma.ai software suite
- Used by most of the top-20 pharma
- First AI-designed drug into Phase 2
- $2.75B Eli Lilly partnership
- Enterprise-only, opaque pricing
- Built for pharma R&D, not general users
- No approved drug yet
- Heavy domain expertise required
