## Summary

Anthropic says its Mythos 5.2 model found a new way to predict the structure of whole capsids, the protein shells used to deliver gene therapies. In its tests, the model accurately modeled 28 of the 34 capsids it attempted. Anthropic says biologists could use it to design capsids faster and more cheaply.

## Why it matters

The source reports a concrete accuracy result, 28 of 34 capsids modeled, which lets readers gauge how far the method can be trusted for capsid design.
