Frequently asked questions
How should I choose a provider?
Start with automatic routing. To select a public provider, choose its code and copy the updated example. Retries remain within that provider.
How are performance metrics updated?
Metrics update from request records. Latency covers completed successful requests; metrics without valid records display —.
Can I use this model in another client?
The client must support the model’s protocol and a custom API URL. See tool integration guides ↗
