Chai-2 entered the model lineage

Why this model matters

Chai-1 is a multi-modal biomolecular structure model on par with AlphaFold 3 for predicting proteins with ligands, nucleic acids and multimers. Chai Discovery (backed by OpenAI and Thrive) released it free for research and drug discovery, and followed with Chai-2 for zero-shot antibody design.

Current evidence boundary

• Performance depends on the evaluation dataset and operating conditions.
• Task-specific benchmark results should not be compared across unlike domains.
• Outputs require task-specific scientific and experimental validation.
