Token prices
USD per million tokens via OpenRouter, Z.AI (z-ai/fp8). Checked 2026-10-17 12:32 UTC.
| Token type | USD /1M |
|---|---|
| Input | $0.15 |
| Output | $0.5 |
| Cache read | $0.03 |
| 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.
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) - Claude Haiku 5.5 is priced the same or lower and at least as capable.
- On frontier DeepSWE pass@1 (agentic coding) (measured USD per task) - no tracked model currently beats it on both price and capability.
