Cognition's SWE-2

Cognition's SWE-2 is an advanced coding AI model designed for developers and AI enthusiasts seeking cost-effective yet powerful code generation solutions. Built on the foundation of Kimi K3 with reinforcement learning, SWE-2 optimizes both for performance and affordability. It achieves impressive results on the FrontierCode 1.1 Main benchmark, matching Fable 5.1's capabilities at a fraction of the cost—specifically, 64% less—while also nearing GPT-6 Astra's performance at a quarter of the price. Compared to its predecessor, SWE-1.7, it requires 58% fewer turns and costs 81% less, all while delivering higher scores. Available via Devin Desktop and CLI, SWE-2 is ideal for teams and individual developers looking to streamline their coding workflows without breaking the bank. Its balance of capability and cost-efficiency makes it a standout choice for AI-driven code generation in various development environments.
