Agent routing selects which model, tool, or action path an agentic system should take at each decision point — often the highest-frequency operation in multi-agent workflows.

Key Points

  • 2026-10-07: strands-decider-2b targets routing with ~115ms latency and calibrated confidence — viable for per-step decisions
  • Decision models avoid token-generation overhead for binary/choice/score questions
  • Connects to hybrid architectures: fast System One routing + LLM for complex reasoning
