SWE-2 Flash: Cognition's 3x-Faster, 5x-Cheaper Coding Model, Explained

Automated excerpt

SWE-2 Flash is a 276-billion-parameter mixture-of-experts model with 12 billion parameters active per token, adapted from Thinking Machines Lab's Inkling-Small base model (weights released July 30, 2026). DeepSWE 1.1: SWE-2 scores higher here too. SWE-2's Devin list price is $3.00 per million input tokens and $15.00 per million output tokens, so one-fifth works out to roughly $0.60 input / $3.00 output per million tokens.
