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
