hybrid-llm-model-pattern-opus-haiku-pipeline-stages

For a 23-stage pipeline, assign Claude Opus 4.6 to the 8 critical reasoning stages (hypothesis generation, experiment design, paper writing, peer review simulation) and Claude Haiku 4.5 for the 15 routine stages (topic init, resource planning, export, formatting). AutoResearchClaw natively supports primary + fallback model config. Haiku 4.5 is preferred over GPT-4o-mini to stay within the Anthropic ecosystem and avoid cross-provider API complexity. This hybrid approach delivers zero-compromise quality at the stages where it matters without wasting tokens on mechanical operations.
