Token prices
USD per million tokens via OpenRouter, xAI (xai). Checked 2026-10-17 04:40 UTC.
| Token type | USD /1M |
|---|---|
| Input | $2 |
| Output | $6 |
| Cache read | $0.5 |
| 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. Long-context tiers apply; use the comparison page for a prompt length estimate.
Frontier position
- 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.
- Behind frontier AA intelligence index (blended per-1M-token price, 3:1 input/output; not a measured per-task cost) - Qwen3.8 Max (0902), Grok 4.7, Qwen3.8 2.4T A95B, Grok 4.5, GLM-5.3 are priced the same or lower and at least as capable.
- Behind frontier DeepSWE pass@1 (agentic coding) (measured USD per task) - Claude Opus 5, GLM-5.3, GPT-5.6 Luna, GPT-5.6 Sol, GLM-5.3-Flash are priced the same or lower and at least as capable.

Benchmark scores
Measured cost per task (DeepSWE)
| Benchmark | Pass@1 | Measured cost / task | Frontier |
|---|---|---|---|
| DeepSWE (agentic coding) (high effort, 95% CI 63.6%-66.7%, 4 runs) | 65.2% | $4.38 (median $3.69) | behind |
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 |
|---|---|
| AA intelligence index | 44.3 |
| AA coding index | 76.8 |
