SWE-1.7
Cognition ships SWE-1.7 at 1000 tokens per second
An RL fine-tune of Moonshot's open Kimi K2.7 base (disclosed up front, unlike SWE-1.5's hidden GLM base), lifting FrontierCode from 30.1% to 42.3% — tied with GPT-5.5 though still behind Opus 4.8. Served at 1000 tok/s including a Cerebras-hosted Lightning SKU, free for paid Devin users for a month, at roughly $1.97 per task. No public API at launch; Devin and Windsurf only.
