This setting lets you override Claude Code’s main model and, at the same time, point a smaller, faster model at helper operations.
That’s handy for testing new versions or using deployments specific to your organization.
With two models defined, heavy tasks go to the main one and light tasks to the helper, optimizing cost.
When to use
- When testing a new model version or a corporate endpoint.
- When you want to split heavy and light tasks across different models.
- In organizations with their own model deployments.
How to use
Apply the setting and adjust the main and helper models to the identifiers you use.
