  • SWE-grep and SWE-grep-mini are fast agentic models specialized in highly parallel context retrieval.
  • These models match the retrieval capabilities of frontier coding models while being significantly faster.
  • Context retrieval in coding agents traditionally faces a tradeoff between speed and intelligence.
  • SWE-grep models use up to 8 parallel tool calls per turn, reducing search time from 6 to 4 turns.
  • The models are trained with multi-turn reinforcement learning and distilled for efficiency.
  • Fast Context subagent is integrated into Windsurf, reducing time to understand large codebases.
  • Evaluation shows SWE-grep models outperform frontier models in speed and retrieval accuracy.
  • The goal is to keep users in flow by minimizing response times below 5 seconds.
  • Future directions include higher intelligence, variable turn length, and tool speed optimizations.
