Claude achieves over 30% success rate in de novo protein design
AnthropicAI · x · 2026-08-19
Anthropic announced breakthrough results for Claude in scientific tasks.
Protein Design
- Task: Designing protein binders from scratch, a key step in drug development.
- Results: Successfully designed binders for 14 out of 15 targets. 22%-35% of designs bound successfully, significantly surpassing the industry baseline of 10%-15%.
- Performance: Some top designs bound several times more tightly than the best published de novo binders.
- Validation: Independently built and tested by Adaptyv Bio and Twist Bioscience.
Chemical Analysis
- Task: Analyzing NMR and LC-MS data to assess compound purity.
- Results: Claude Opus 5 completed analysis in 19-23 minutes with a purity determination of 96.4%, matching the lab's 96.33%.
Future Plans
- Prioritizing an access program for scientists to use their most capable models.
- Teaching Claude to run the end-to-end development process for every major type of drug molecule, from antibodies to small molecules.
