Before your first call

An inference call needs an API key and a positive wallet balance. The first call to an idle model can answer 503 with a Retry-After header while it starts — wait, then retry. Full reference: the API docs.

How is Qwen-3.5 licensed?

Qwen-3.5's upstream licence is recorded in our model licence index rather than on this page. The obligations we pass through are listed on model licences, and the model card itself is at its source.
