Price check: official, OpenRouter and Wokey

USD per million tokens. Official and OpenRouter rates were checked by hand on 2026-09-23, excluding tax; the Wokey rate is read from the live price list.

The cheapest OpenRouter host is Sail Research's fp4-quantized deployment ($1.4989 input / $10.758 output). Quantized output can differ from the official weights, so it is not in the table.

Source of this call

This call used the Volcengine channel at ark.cn-beijing.volces.com with API Key authorization. Usage was metered upstream and the request returned HTTP 200.

Verify Prompt Cache

1. Keep the shared prefix of long prompts identical and reuse context according to the selected API’s cache rules.
2. Check prompt_tokens_details.cached_tokens; zero means no cache reads were recorded for this call.
3. Uncached input = prompt_tokens minus cached tokens. Price each bucket separately and add the output charge.
