Cognition releases SWE-2 Flash coding model built on Inkling-Small, weights withheld
Overview
Cognition introduces SWE-2 Flash, a coding model built on Thinking Machines' Inkling-Small, which has 276B total and 12B active parameters.
Cognition says the model outperforms all American open-weight models on leading evals, including ones three times larger, but it is not publicly releasing the weights. Cognition says the weights carry a cyber misuse risk and that it is building a program to share them securely with trusted industry partners and research labs, with more details coming in the coming weeks.
Cognition says its inference stack lets it offer SWE-2 Flash at one-fifth the price and 3x the speed of its larger sibling SWE-2. Cognition's blog says Terminal-Bench 4.0 scores rose from 0.9% to 20.0% over the base model Inkling-Small. SWE-2 Flash is free until the end of the month for Pro, Max, and Teams users in Devin Desktop and Devin CLI.

AICognition introduces SWE-2 Flash, a coding model it calls fully American, available today in Devin Desktop and CLI at one-fifth the price and 3x the speed of SWE-2. Cognition says Terminal-Bench 4.0 scores rose from 0.9% to 20.0% over the base model Inkling-Small, and the company is not publicly releasing the weights because of cyber misuse risk, instead planning a program to share them with trusted industry partners and research labs.
