Claude playbook guides model selection and multi-model workflows
The Claude Developer Blog published a playbook by Addy Osmani on choosing among Claude Fable 5.2, Opus 5.5, Sonnet 5.5, and Haiku 5.5. It covers task-based selection, effort levels, token costs, context and cache considerations, and combining models, with recommendations ranging from Haiku for high-volume classification to Fable for difficult technical projects.
The guide gives developers concrete first-party guidance on balancing Claude model capability, cost, and effort when designing individual tasks or multi-model systems.
