KaiGPT (gptzzz.ai, site name "gptzzz.ai", subtitle "AI API 中转服务 中转站") is an independent third-party AI API relay (中转站) and multi-model gateway for Chinese-speaking developers. It exposes an OpenAI-compatible interface at https://gptzzz.ai/v1 (chat completions, Responses, embeddings, images), a Claude Messages route at https://gptzzz.ai/v1/messages and a Gemini-style v1beta surface, authenticated with a KaiGPT API key via Authorization Bearer, x-api-key or x-goog-api-key. Model IDs, group multipliers and limits are shown only in the logged-in console; the public model plaza lists no models or prices yet. It also ships a desktop client that configures Claude Code, Codex, Gemini CLI and OpenCode, and a Chinese knowledge base on relay selection, security and compliance. KaiGPT states it is not affiliated with the model vendors it routes to; it resells access to other providers' model APIs rather than training models itself.
