9This pattern fits long-horizon agentic workloads (coding agents, computer use, multistep research pipelines) where most turns are mechanical but having an excellent plan is crucial. You get close to advisor-solo quality while the bulk of token generation happens at executor-model rates.
9This pattern fits long-horizon agentic workloads (coding agents, computer use, multistep research pipelines) where most turns are mechanical but having an excellent plan is crucial. You get close to advisor-solo quality while the bulk of token generation happens at executor-model rates. For measured results, including how the benefit shrinks as the executor's own capability approaches the advisor's, see [Optimizing for cost and intelligence](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence).
