Picking a model
Rough guidance:- Default to Claude Sonnet. It hits the best balance of quality and cost for most agent workloads.
- Move to Haiku or Flash if latency and per-call cost matter more than reasoning depth (for example, a classifier agent that only picks a label).
- Move to Opus only when a task consistently fails at Sonnet — the cost delta is substantial.
Changing the model
Open the agent’s detail page and edit the Model field. The change applies to all new conversations; conversations already in progress continue on whichever model they started.Next steps
