hybrid-opus-haiku-routing-for-long-research-pipelines
For 23-stage research pipelines, route Claude Opus 4.6 only to the 8 critical reasoning stages (hypothesis generation, experiment design, paper writing, peer review simulation) and Haiku 4.5 to the 15 routine stages (topic init, resource planning, export, formatting). This achieves maximum intelligence where it matters with minimal token consumption for procedural stages. AutoResearchClaw supports primary + fallback model config natively to enable this pattern.
