The honest brief
BioNeMo
GPU-optimized recipes claim ~2x faster biofoundation-model training and ~6x faster inference versus unoptimized pipelines.
- Open-source framework (Apache-2.0)
- Prebuilt models for protein and molecule tasks
- NIM microservices for production deployment
- Bundles datasets and training recipes
- Requires NVIDIA GPUs
- Steep learning curve for non-ML scientists
- Production microservices are paid
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
