Use session usage when a conversation is becoming long, a model feels expensive, or you want to understand how much context OpenCode is carrying.
## Open the usage sheet
Tap the usage indicator in the Chat header. The sheet summarizes the current session and active model. If the app has only a partial transcript window loaded, totals may cover loaded history only; the sheet says so when that applies.
The usage sheet follows the website’s current color theme.
## Read the numbers
- **Context utilization** is the portion of the model's input window currently represented by session input.
- **Input** and **output tokens** measure text sent to and returned by the model.
- **Reasoning tokens** are reported separately when the provider supplies them.
- **Cache read/write** shows reused or newly cached context when supported.
- **Steps** counts recorded assistant processing steps.
- **Estimated cost** appears only when the server has usable pricing metadata.
“Pricing unavailable” does not mean the request was free. It means the app cannot calculate a reliable amount. “Included or unpriced” may represent subscription-included usage or missing provider pricing.
## Use the information
- Start a fresh session when unrelated history is consuming context.
- Keep one session focused on one outcome.
- Choose a smaller model for routine follow-ups when appropriate.
- Treat cost as an estimate and use the provider's billing dashboard as the source of truth.
- Compact or reset a session before it becomes difficult to review.
