## Summary

Adaption says AutoScientist raised correctness on medical long-horizon reasoning from 58.1% to 75.2%, beating GPT-6 Astra and Gemini 4 Argon. The system works on any open-weights starting model and needs no retraining. Adaption reports the lower-cost model ran at up to 15.4x lower cost than those two.
