hybrid-opus-haiku-for-researchclaw-stage-routing

AutoResearchClaw internally supports primary + fallback model configuration. Use Claude Opus 4.6 for the 8 critical reasoning stages (hypothesis generation, paper writing, peer review, claim verification) and Claude Haiku 4.5 for the 15 routine stages (topic init, resource planning, export, formatting). Staying within the Anthropic ecosystem avoids external API dependencies. This was confirmed over GPT-4o-mini as fallback to keep the entire pipeline on a single provider.
