USD per million tokens via OpenRouter, Anthropic (anthropic). Checked 2026-11-07 23:56 UTC.
| Token type | USD /1M |
|---|---|
| Input | $4 |
| Output | $20 |
| Cache read | $0.2 |
| Cache write (5 minutes) | $5 |
| Cache write (1 hour) | $8 |
Cache-write rates with a verified basis replace the ordinary input charge. Unknown rates are never treated as zero.
- On frontier AA intelligence index (blended per-1M-token price, 3:1 input/output; not a measured per-task cost) - no tracked model currently beats it on both price and capability.
This model has not been measured on DeepSWE (or any other benchmark with a real measured per-task cost) yet, so no cost/capability chart is drawn. Its Artificial Analysis benchmark scores are listed below.
Measured cost per task (DeepSWE)
This model has not been measured on DeepSWE (or any other benchmark with a real measured per-task cost) yet.
Artificial Analysis scores
Artificial Analysis scores describe capability. Compare them against estimated token spend with your cache mix; these estimates are not measured task costs.
