Quick Configuration Guide

​
1️⃣ Global npm Package Installation

Run in terminal: 
npm install -g @aihubmix/claude-code@latest
Replace sk-*** with your API key generated on AiHubMix. Configuration items other than models will be processed with system environment variables taking priority. 
export AIHUBMIX_API_KEY="sk-***"
export HOST="127.0.0.1"  # Optional
export PORT="3456"        # Optional
export LOG="true"         # Optional
export API_TIMEOUT_MS="30000"  # Optional
  • For Mac users, you can navigate to your username directory and press ⌘ + ⇧ + . to show the hidden .zshrc file, then open it with the system’s “TextEdit” app and add the above content.
  • After adding the configuration, run source ~/.zshrc in terminal and press enter to make the configuration effective.

​
3️⃣ Generate Configuration File

Replace sk-*** below with your AiHubMix API key, then run this one-liner in terminal: 
mkdir -p ~/.aihubmix-claude-code && cat > ~/.aihubmix-claude-code/config.json <<EOF
{
  "API_KEY": "sk-***",
  "HOST": "127.0.0.1",
  "PORT": 3456,
  "LOG": true,
  "API_TIMEOUT_MS": 30000,
  "Router": {
    "default": "gpt-5",
    "background": "claude-3-5-haiku-20241022",
    "think": "gpt-5",
    "longContext": "gpt-5",
    "longContextThreshold": 60000,
