Remaining usage is not a fixed prompt count. Estimate a range from the cost of your most similar recent task.
Start with both account windows
Record short-window and weekly signals plus any recovery time. Looking at only one percentage can hide the limit that will stop you first.
Estimate by workload
A short explanation, a single-file change and an agentic repository migration have very different costs. Use a comparable completed task and add a buffer for debugging.
- Explanation: low
- Scoped implementation: medium
- Long agent run: high
Reduce wasted usage
Include the goal, relevant file paths and validation command up front. Stop a task early when its direction is wrong instead of paying for a full failed run.
Frequently asked questions
Why can the same prompt cost differently?+
Context size, tools, repository scope and run time all influence consumption.
Can I convert the allowance into an exact prompt count?+
Usually not. Low, medium and high cost bands are more useful.
