Summary

Anthropic published lab-validated results showing Claude (Mythos Preview and Opus 4.8) designed protein binders against 14 of 15 targets tested by Adaptyv Bio and Twist Bioscience, hitting 22-35% success versus the typical 10-15% industry rate. Opus 5 also processed raw NMR and LC-MS data in 23 and 19 minutes with purity within 0.1% of the lab's own reading. Anthropic says life-science tasks remain blocked in its most capable model and it is preparing an access program for scientists.
