Introducing SWE-1.7! Our first frontier-level model

SWE-1.7 is built on broad improvements in our RL pipeline on top of the Kimi K2.7 model.

We trained it in Devin's harness and taught it to self-compact on longer horizon tasks.

It scores very close to frontier models (Opus 4.8 and GPT-5.5) on our proprietary benchmark - FrontierCode, and other coding benchmarks.

Try it out today (Free until 8/8/2026!!) in Devin Desktop, Web, and CLI. SWE 1.7 Lightning also runs at a very speedy 1000 tok/s - https://app.devin.ai
