GPT-5 mini

Official list price in the directory snapshot: ¥1.67 input and ¥13.37 output per 1M tokens, in CNY. Relay prices below are what individual sites listed; they can be lower or higher, and they are not official prices.

12 sites in our public directory listed this model ID in the 2026-10-26 snapshot. Listed relay price range: ¥0.022–¥1.75 per 1M input tokens. A listing means the model appeared on the site's public model list; it is not proof that the site serves the genuine model.

1. Send a short request to the relay and read the model field in the response. It must match the ID you sent; a different ID is a mapping, not necessarily a substitution.
2. Run the same prompt against a known-good endpoint and compare prompt-token counts. A large, repeatable gap points at a different tokenizer or a different backend.
3. Run the seven checks. Billing, context retention, error shape, parameter compliance, tools, and streaming each produce evidence you can quote.

Is a relay really serving GPT-5 mini?

A model ID in a response is not proof. The seven-check detection compares tokenizer ratios, billing, error shape, parameter compliance, tools, and streaming against the advertised family. Run it on a key you can afford to spend, and treat one run as a spot check, not 24/7 monitoring.
