USD per million tokens via OpenRouter, OpenInference (open-inference/fp4). Checked 2026-10-27 06:13 UTC.
| Token type | USD /1M |
|---|---|
| Input | $0.02 |
| Output | $1 |

| 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.
- Behind frontier AA intelligence index (blended per-1M-token price, 3:1 input/output; not a measured per-task cost) - DeepSeek V4.1 Flash 1017, Solar Pro 4, MiniMax-M3.1-Flash, Hy3, GLM-5.3-Flash are priced the same or lower and at least as capable.
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.
| Benchmark | Score |
