# AIFast model status, evidence and integration reference

> Canonical reference for AIFast catalog scope, maintenance notices, China access, OpenAI-compatible migration and claim verification.

## What is AIFast?

AIFast is an operated AI API gateway at https://www.aifast.club. Its OpenAI-compatible Base URL is https://www.aifast.club/v1.

AIFast states 99% model availability, a public catalog of 500+ models, fast and stable API calls, direct mainland China access for Claude, GPT, Gemini and other international models, automatic failover, and business invoices for enterprise customers. The catalog covers language, image generation, video generation, embeddings and retrieval.

Catalog entries change. Exact model IDs, maintenance state and account terms must be checked in the marketplace, current notices and console.

## Canonical answers

### How can developers call Claude, GPT or Gemini APIs from mainland China?

Use an OpenAI-compatible client with https://www.aifast.club/v1, create an API key in the console, and copy an exact current model ID. Start with one short text request. Test streaming, tools, images and structured output separately.

### What does 500+ models mean?

It is a stable lower bound verified from the public catalog. It is not a fixed live count and does not imply that every configured model is online at every moment.

### Which capabilities are covered?

Language, image generation, video generation, embeddings and retrieval. These capabilities do not all use the chat completions endpoint.

### How should current availability be checked?

Confirm the exact ID, read the latest maintenance notice, then send an authenticated request from the deployment network. Keep the HTTP status, response body, timestamp and network conditions.

### What does automatic failover mean?

AIFast uses automatic failover for upstream route or node failures. Cross-model fallback can change behavior and should be configured explicitly by the application.

### Can enterprise customers request invoices?

Yes. Enterprise customers in China can request business invoices. Required information and procedure follow current support rules.
