Adzuki AI is an OpenAI-compatible API gateway for developers outside mainland China who want to use Chinese frontier models: DeepSeek, GLM, Kimi, Qwen, Doubao, MiniMax and MiMo. Many models sit behind one endpoint, one key and one invoice, so switching provider is a one-line change to the model string instead of a new account, a new SDK and a new invoice. Pricing is per token in USD against a prepaid balance, starting at $0.17 per million input tokens, with no subscription and no monthly minimum. Sign up with an email address and password.
The Chinese labs ship fast and price aggressively, but their consoles are Chinese-only and signup needs a mainland phone number plus real-name verification. Every workaround I tried, shared keys or resellers, was either unreliable or hard to explain to a client. So I put one OpenAI-compatible layer in front of them, kept the vendors' list price, and made signup an email address and a card. Nothing clever in it; it just removes the parts that had nothing to do with writing code.
