hybrid-llm-strategy-for-long-research-pipelines

AutoResearchClaw’s 23-stage pipeline uses a hybrid LLM model: Opus 4.6 for the 8 critical reasoning stages (hypothesis generation, experiment design, paper writing, peer review) and Haiku 4.5 for the 15 routine stages (topic init, resource planning, formatting, export). AutoResearchClaw natively supports primary + fallback model configuration. Staying within Anthropic ecosystem (Opus + Haiku) rather than mixing with OpenAI/Gemini avoids credential sprawl and maintains consistent quality guarantees.
