Cognition· Devin / SWECapability change

Cognition introduced Devin Fusion, a multi-model harness that uses a frontier model and a cost-effective 'sidekick' model in parallel, achieving up to 60% cost reduction on the FrontierCode benchmark while maintaining performance. The system is available in preview on Devin.

we're sharing our work on a new kind of multi-model harness, Devin Fusion, that is substantially better at mixing models while reducing costs and maintaining intelligence on real-world usage.
