With SWE-1.6 we've made significant progress on "intelligence per token". We post-trained the model from scratch (same pre-trained model) with a similar recipe as SWE-1.6 Preview. Our latest algorithm achieves similar intelligence at ~40% fewer assistant turns. We also shipped further infra improvements, so our latest training run was 1.6x faster end-to-end for the same amount of FLOPs. In our next training run, we're aiming to 5x the FLOPs. We’re releasing SWE-1.6, our best model in both intelligence & model UX. SWE-1.6 matches our Preview model on SWE-Bench Pro while dramatically improving on various behavioral axes. It’s available today in Windsurf in two modes: free tier (200 tok/s) and fast tier (950 tok/s).
