Reporting Use Cases

The Model context tier field distinguishes ordinary requests from extended-context ones, which are priced differently and consume far more input tokens.

  • Understanding input token growth: Long-context work is the usual explanation for input tokens growing much faster than interactions.

  • Cursor max mode adoption: Grouping Cursor records by context tier shows how much of the team's work runs in max mode.

  • Sparsely populated: Only Anthropic and Cursor expose a context tier today.
