490490## Changing the budget mid-conversation

492`task_budget` is a request-level setting. To change the budget partway through a task, for example to extend it when the user broadens the request, set a new `task_budget` in `output_config` on the next request. Keep the caching consequence in mind: the budget value participates in the rendered prompt, so a changed value does not match cache entries created under the old one (see [Feature support](https://platform.claude.com/docs/en/build-with-claude/task-budgets#feature-support) below).
