Reasoning-effort configurations
The same model behaves differently depending on how much it is allowed to think. Each row is one setting, scored only on the benchmarks that were run at that setting. “Default” means the publisher did not say which setting was used.

What a task costs
Estimates from list price, output speed and time to first answer for the best configuration. “With caching” assumes three-quarters of the input is served from the prompt cache. Reasoning tokens are not modelled.
| Workload | Tokens in / out | Cost | With caching | Time |
|---|---|---|---|---|
| Chat reply | 400 / 300 | $0.0007 | – | 13.1 s |
| Summarise a 30-page report | 12,000 / 600 | $0.0069 | – | 25.6 s |
| Code edit | 6,000 / 1,500 | $0.0053 | – | 1.1 min |
| Agentic coding session | 60,000 / 4,000 | $0.036 | – | 2.8 min |
