researchclaw-hybrid-llm-haiku-not-gpt4o-mini

AutoResearchClaw’s internal pipeline uses a hybrid LLM strategy: Claude Opus 4.6 (via ACP) for the 8 critical reasoning stages (hypothesis gen, paper writing, peer review) and Claude Haiku 4.5 for the 15 routine stages. GPT-4o-mini was initially proposed for routine stages but rejected — stay within the Anthropic ecosystem to preserve prompt cache sharing and avoid external API dependencies. AutoResearchClaw natively supports primary + fallback model config.
