GPTZZZ

GPTZZZ is an independent third-party AI API relay service that lets developers access multiple model families, including GPT/Codex, Claude, Grok, DeepSeek, and GLM, through a single account and unified balance. It provides OpenAI-compatible endpoints, so you can switch from the official API by changing the Base URL to https://gptzzz.ai/v1. The service is designed for developers and teams who need to integrate various AI models into their applications, coding assistants, or agents without managing multiple accounts.

How it works

GPTZZZ works by providing a single API endpoint that routes requests to different model families. You create API keys for specific groups, each with its own multiplier and model list. For example, the '混合号池pro兜底' group has a 0.1x multiplier and includes models like gpt-5.5 and gpt-6, while the 'claude_kiro' group has a 0.4x multiplier and includes Claude models. To use it, you change the Base URL in your OpenAI-compatible client to https://gptzzz.ai/v1, and for Claude models, use the /v1/messages endpoint.

Key capabilities

GPTZZZ supports 27 models across 5 model families: GPT/Codex, Claude, Grok, DeepSeek, and GLM. It offers OpenAI-compatible endpoints with tested features including /v1/models, /v1/chat/completions, /v1/responses, streaming SSE, tool calling, JSON mode, and base64 image input. The service also provides a public status page and detailed documentation for integration. Pricing is transparent, with group multipliers as low as 0.1x, and each model's price per million tokens is listed in the model plaza.

Who it is for

GPTZZZ is aimed at developers and teams who need to integrate multiple AI models into their applications. It is suitable for backend services, coding assistants, agents with tool calling, streaming conversations, and batch text processing. The service is particularly useful for those who want to avoid managing separate accounts for different model providers and prefer a unified billing system. It also provides guidance for production use, including security practices and cost control.

Pricing and limits

GPTZZZ is a paid service with no free tier. You top up via Alipay with a minimum of ¥10, and the exchange rate is ¥1 = $1 in balance. There are no transaction fees, and unused balance can be refunded anytime. Pricing is based on usage, with per-million-token rates varying by group and model. For example, gpt-5.5 in the '混合号池pro兜底' group costs $0.50 input and $3.00 output per million tokens. The service does not offer invoices as it is individually operated.
