FAQ
What is an LLM gateway?
An LLM gateway is a proxy layer between your app and model providers. It exposes one API for routing, failover, billing, and usage tracking across many models.
What is ZBStream?
ZBStream is an LLM gateway for developers. One API key and an OpenAI-compatible endpoint let you call models from multiple providers without rewriting your client.
How is ZBStream different from calling a model vendor directly?
Direct vendor APIs lock you to one provider. ZBStream unifies authentication, model IDs, routing, and credit billing so you can switch or fail over without changing application code.
Does ZBStream work with the OpenAI SDK?
Yes. Point the OpenAI SDK at the ZBStream base URL, set your ZBStream API key, and send Chat Completions or Messages requests as usual.
