How much detail would you like?
Practical
Relevant for agents with long histories, many tools and extensive retrieval.
Sample scenario: A support agent limits old messages so that current error data and relevant manual locations can be accommodated.
Set budgets per component, measure actual consumption and receive mandatory information if reduced.
At a glance
- Core
- A context budget specifies how much space individual input parts receive. Depending on the API, output or further processing must also be considered. It is a planning parameter and not a uniformly standardized parameter; the meaningful distribution depends on the task and the model.
- Use

- Limits
- Filling the entire window with documents; forgetting output reserve; optimizing token numbers instead of information benefits.
