- Models affected: SWE-grep, SWE-grep-mini

Cognition released SWE-grep and SWE-grep-mini, fast agentic models specialized in multi-turn, highly parallel context retrieval. These match the retrieval capabilities of frontier coding models while taking an order of magnitude less time. They power the new Fast Context subagent in Windsurf.

## Evidence

Verbatim from https://cognition.com/blog/swe-grep:

> These models now power Fast Context , a subagent that helps you stay in flow.
