DeepSeek V4 Flash 0731

The snapshot does not record an official list price for this model. We do not estimate one. Ask the provider or read the relay's own pricing page before budgeting.

24 sites in our public directory listed this model ID in the 2026-10-26 snapshot. Listed relay price range: ¥0.057631–¥3 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 DeepSeek V4 Flash 0731?

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.
