General FAQ
What is Chuizi.AI?
Chuizi.AI is a unified AI API gateway. With one baseURL and one API key, you get access to 200+ models across 17 providers including OpenAI, Anthropic, Google, DeepSeek, Qwen, GLM, Kimi, MiniMax, and more.
Requests use the OpenAI-compatible protocol by default, with native Anthropic and Gemini protocols also available. Your existing code, SDKs, and tools work instantly — just change your baseURL and API key.
How is this different from calling each provider directly?
Calling each provider directly means managing separate accounts, multiple API keys, different billing systems, and inconsistent error formats. Chuizi.AI solves all of that:
- Unified billing — one balance for all models
- Automatic failover — when a provider goes down, requests route to backup channels automatically
- Consistent error format — all errors return in OpenAI-compatible format, no provider-specific error handling needed
- One key for everything — a single
ck-prefixed API key works across all models and protocols
