Routing strongest model every turn is bad design: one route per turn, pin through tools
WirelessLife · x · 2026-10-22
The author argues that always picking the strongest model is bad systems design and lays out routing principles for agent workflows:
- Route once per turn instead of re-evaluating constantly
- Pin the model through the tool chain for consistency
- Filter candidates by context and policy before scoring
- Optimize for reliable completion, not the cheapest single request
A practical counterpoint to cost-based dynamic model selection in multi-step workflows.
