Overview

To meet developers’ needs for leveraging the Anthropic API ecosystem, our API now supports accessing all models via the Anthropic API interface.
It supports 200+ LLMs, including 7 free models.

​

Usage Example

​
Using GPT-5.2 in Claude Code

Although any supported model can be used via AIHubMix, for the best experience we recommend high-capability models such as gpt-5.2 or glm-4.7.

​
1. Install and Configure Claude Code

Refer to the Claude Code installation guide: https://docs.aihubmix.com/cn/api/Claude-Code

​
2. Connect Claude Code to AIHubMix

Claude configuration file: .claude/settings.json 
{
  "env": {
    "ANTHROPIC_API_KEY": "AIHUBMIX_API_KEY",
    "ANTHROPIC_BASE_URL": "https://aihubmix.com",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "gpt-5.2",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "gpt-5.2",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "gpt-5.2",
    "ANTHROPIC_MODEL": "gpt-5.2"
  },
  "includeCoAuthoredBy": false
}
Replace AIHUBMIX_API_KEY with your actual AIHubMix API key.
The native Claude Code installer cannot read standard .env files. Do not place these settings in a .env file.

​
3. Start a Conversation

Navigate to your project directory and launch Claude Code: 
$ cd /path/to/your-project
> claude
Once connected successfully, all prompts you send will be routed through AIHubMix.

​
4. Verification

You can verify the connection by running the /status command in Claude Code: 
> /status
