How many models does the relay support?

The panel lists a total of 452 models for sale. The available model details list only the 150 models with higher usage volumes, so the complete support scope cannot be inferred from them.

How does calling Claude Fable 5 through a relay differ from direct official access?

Calling through a relay adds an extra network hop and may involve delays in supporting official new features, model parameters, or API behavior. Before integration, independently verify latency, stability, authentication, request formats, and error handling.

What are the context length and time to first token for Claude Fable 5?

The context length and measured time to first token for Claude Fable 5 have both yet to be verified through testing. The pricing data provided on the page does not include either item, so actual test records should be used as the reference.
