WHY WE PICKED IT
SWE-2 is a genuine data point in the trend of labs fine-tuning open-weight Chinese base models to compete with closed frontier coding models on price, and it is the model Cognition is betting Devin's entire value proposition on. The catch is access: every benchmark above is Cognition's own, unverified independently, and there is no way to use the model outside Devin's ecosystem.
GETTING STARTED
Use SWE-2 through Devin's desktop app or CLI; it is selectable as a model option and is free to run there through mid-October 2026. After that, it requires a paid Devin plan (Pro starts at $20/month). It is not available as a standalone self-serve API or as downloadable weights.
