USD per million tokens via OpenRouter, Meta (meta). Checked 2026-10-18 21:27 UTC.
| Token type | USD /1M |
|---|---|
| Input | $1.25 |
| Output | $4.25 |
| Cache read | $0.15 |
| Cache write (default) | Unknown |
| Cache write (1 hour) | Unknown |
Cache-write rates with a verified basis replace the ordinary input charge. Unknown rates are never treated as zero.
- On frontier AA coding 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.
- 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.
