How to verify this model on a relay

THREE STEPS
  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.

Questions

FAQ

What is the context window of Claude Opus 4.8?

The snapshot records 1,000,000 tokens.

How much does Claude Opus 4.8 cost?

Official list price: ¥33.42 input / ¥167.12 output per 1M tokens in CNY, per the directory snapshot. 24 relay sites listed it at ¥0.10625–¥8 per 1M input tokens.

Is a relay really serving Claude Opus 4.8?

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.
