How this is measured

Every hour we send one identical prompt to GPT-5.6 Terra through a single gateway account, record how long the call took and what it was billed, then divide that cost by the tokens consumed to get an observed price per million tokens.

Benchmark figures come from a fixed suite of code-graded tasks re-run against every tracked model. Scores are the share of available points earned; cost is the average spend per task.

These are one buyer's readings on one route. Enterprise pricing, batch discounts and cached-input rates will differ.
