SWE 1.6

Abstract

We are sharing an early preview of our ongoing SWE-1.6 training run. Since training SWE 1.5, we have refined our RL recipe and scaled our infrastructure to unlock two orders of magnitude more compute. Our next model SWE-1.6 is post-trained on the same pre-trained model as SWE-1.5 and runs equally as fast at 950 tok/s. The current checkpoint achieves an 11% higher score than SWE-1.5 on SWE-Bench Pro.
