Kenning's take

What it does

SWE-2 is Cognition's in-house model for software engineering, used by the Devin coding agents. It comes in Medium, High and Max reasoning-effort versions, and Cognition says it scores close to leading frontier models on coding benchmarks at a lower cost. It is available in Devin Desktop and the Devin CLI, and is rolling out to Devin Web and Fusion.

  • Medium, High and Max reasoning effort
  • Post-trained from Kimi K3 with reinforcement learning
  • 50.0% on FrontierCode 1.1 Main, per Cognition
  • Fewer steps per task than SWE-1.7
  • Available in Devin Desktop and CLI

Who it suits. Developers using Devin Desktop, the Devin CLI or Devin Web for coding agents.
