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.

Where it wins
Benchmarks where this configuration ranks in the top five of every configuration measured.
Where to run it
Every provider serving this model through OpenRouter, with throughput and first-token latency measured on live traffic over the last 30 minutes and each provider’s own price. Purple marks the best in each column.
| Provider | Speed | First token | Input $/M | Output $/M | Context | Quantisation |
|---|---|---|---|---|---|---|
| Meta | 194 tok/s | 2.03 s | $1.25 | $4.25 | 1.0M | – |
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 at $0.150 per 1M. Reasoning tokens are not modelled.
| Workload | Tokens in / out | Cost | With caching | Time |
|---|---|---|---|---|
| Chat reply | 400 / 300 | $0.0018 | $0.0014 | 3.6 s |
| Summarise a 30-page report | 12,000 / 600 | $0.018 | $0.0077 | 5.1 s |
| Code edit | 6,000 / 1,500 | $0.014 | $0.0089 | 9.8 s |
| Agentic coding session | 60,000 / 4,000 | $0.092 | $0.043 | 22.7 s |
| Structured extraction | 2,000 / 200 | $0.0034 | $0.0017 | 3.1 s |
