Claude team shares two multi-agent patterns: Advisor and Orchestrator

Claude开发者分享两种多智能体模式：Advisor和Orchestrator

Claude developers shared two multi-agent patterns their team uses heavily. In Advisor mode, Sonnet 5 executes while calling Fable 5 for guidance via tool calls; on SWE-bench Pro the combo hits 84% at $1.40, saving 37% cost vs pure Fable 5 with only an 8-point accuracy drop. In Orchestrator mode, Fable 5 plans and fans out tasks to multiple Sonnet 5 workers; on BrowseComp it reaches 86.8% at $18.53, less than half the cost of all-Fable 5. Both patterns route heavy lifting to cheaper models and reserve expensive ones for key decisions.

Why it matters: Anthropic dev shares two multi-agent patterns with concrete SWE-bench scores and cost breakdowns — directly useful for teams building agents. Score held back because it's an individual share, not an official release, and the Orchestrator mode lacks benchmark numbers.
