Routing Different Models in Agent Workflows Beats Using Claude Opus 5 for Everything: Benchmark Surprises
entelligenceai17 · reddit · 2026-07-30
The author experimented with routing different stages of an agent workflow to different models instead of relying solely on a single frontier model.
- Method: Used the same Claude Code harness on 89 Terminal-Bench 2.1 tasks, comparing routing strategy vs sending every request to Claude Opus 5.
- Findings: Routing strategy performed better on some tasks with lower cost. Full results in comments.
- Discussion: Wondering if others standardize on one model or use different models for different stages.
