How to verify this model on a relay
THREE STEPS- Send a short request to the relay and read the
modelfield in the response. It must match the ID you sent; a different ID is a mapping, not necessarily a substitution. - 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.
- Run the seven checks. Billing, context retention, error shape, parameter compliance, tools, and streaming each produce evidence you can quote.

OpenAIQuestions
FAQWhat is the context window of GPT-5.4 Mini?
The snapshot records 400,000 tokens.
How much does GPT-5.4 Mini cost?
Official list price: ¥5.01 input / ¥30.08 output per 1M tokens in CNY, per the directory snapshot. 24 relay sites listed it at ¥0.02625–¥0.975 per 1M input tokens.
Is a relay really serving GPT-5.4 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.
