Part 2: Using Claude Models Through GitHub Copilot

Now that you have free GitHub Copilot, let's unlock Claude models through it!

Understanding the Setup

GitHub Copilot gives you access to various AI models through its infrastructure. We'll use two main approaches:

  1. OpenCode - An open-source AI coding agent that supports GitHub Copilot
  2. oh-my-opencode - An enhanced plugin system for OpenCode

Method 1: Using OpenCode with GitHub Copilot

OpenCode is a powerful terminal-based AI coding agent that officially supports GitHub Copilot.

What is OpenCode?

OpenCode is an open-source AI coding assistant that runs in your terminal. Think of it as an alternative to Claude Code, but with support for multiple AI providers including GitHub Copilot.

Installation Steps

Step 1: Install OpenCode

For macOS/Linux:

curl -fsSL https://opencode.ai/install.sh | sh

For Windows (PowerShell):

irm https://opencode.ai/install.ps1 | iex

Or using npm:

npm install -g @opencode-ai/opencode

Step 2: Authenticate with GitHub Copilot

  1. Launch OpenCode:
opencode
  1. In the OpenCode interface, run the connection command:
/connect

  1. Select "GitHub Copilot" from the provider list

  2. Complete the GitHub device login flow:

    • A browser will open with a code
    • Go to github.com/login/device
    • Enter the code shown
    • Authorize the application

  3. Done! OpenCode is now connected to your GitHub Copilot account

Step 3: Select Claude Models

  1. In OpenCode, run:
/models

  1. You should see available models including:

    • claude-sonnet-4.5
    • claude-opus-4.5
    • claude-haiku-4
    • gpt-4.1
    • gemini-3-pro
    • And more!

  2. Select your preferred Claude model

Step 4: Configure Your Agents

OpenCode uses different "agents" for different tasks. Configure them in ~/.config/opencode/opencode.json:

{
  "providers": {
    "copilot": {
      "disabled": false
    }
  },
  "agents": {
    "coder": {
      "model": "claude-sonnet-4.5",
      "maxTokens": 5000
    },
    "task": {
      "model": "claude-opus-4.5",
      "maxTokens": 5000
    },
    "title": {
      "model": "claude-haiku-4",
      "maxTokens": 80
    }
  }
}

Step 5: Start Coding!

Now you can use OpenCode with Claude models:

opencode

Example prompts:

  • "Create a React component for a todo list"

Step 3: Use Claude Through Antigravity

Now you can use antigravity-claude-opus-4-5 and other models in OpenCode with Antigravity's rate limits!

Part 4: Using Claude Code CLI with Free Proxies

Want to use the official Claude Code CLI but with free access? Here's how using proxy servers.

Method: antigravity-claude-proxy

This is a proxy server that makes Antigravity's Claude/Gemini models compatible with Claude Code CLI.

How It Works:

Claude Code → Proxy Server → Antigravity API → Claude/Gemini Models

Installation

Step 1: Install the Proxy

Using npx (no installation needed):

npx antigravity-claude-proxy start

Or install globally:

npm install -g antigravity-claude-proxy
antigravity-claude-proxy start

Step 2: Add Google Account(s)

Option A: Use Antigravity (Single Account)

If you have Antigravity installed and logged in, the proxy automatically extracts your token. No setup needed!

Option B: Add Google Accounts via OAuth (Recommended)

For desktop/laptop:

antigravity-claude-proxy accounts add

This opens your browser for Google OAuth sign-in.

For headless servers (SSH, no desktop):

antigravity-claude-proxy accounts add --no-browser

Follow the OAuth URL on another device, then paste the authorization code.

Step 3: Verify Accounts

# List all accounts
antigravity-claude-proxy accounts list

# Verify they're working
antigravity-claude-proxy accounts verify

# Interactive management
antigravity-claude-proxy accounts

Step 4: Start the Proxy Server

antigravity-claude-proxy start

The server runs on http://localhost:8080 by default.

Step 5: Verify It's Working

# Health check
curl http://localhost:8080/health

# Check account status
curl "http://localhost:8080/account-limits?format=table"

Configure Claude Code CLI

Step 1: Create Claude Code Settings

Create or edit the Claude Code settings file:

macOS/Linux: ~/.claude/settings.json Windows: %USERPROFILE%\.claude\settings.json

Add this configuration for Claude models:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "test",
    "ANTHROPIC_BASE_URL": "http://localhost:8080",
    "ANTHROPIC_MODEL": "claude-opus-4-5-thinking",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-5-thinking",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-5-thinking",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-sonnet-4-5",
    "CLAUDE_CODE_SUBAGENT_MODEL": "claude-sonnet-4-5-thinking"
  }
}

Or for Gemini models:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "test",
    "ANTHROPIC_BASE_URL": "http://localhost:8080",
    "ANTHROPIC_MODEL": "gemini-3-pro-high",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "gemini-3-pro-high",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "gemini-3-flash",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "gemini-2.5-flash-lite",
    "CLAUDE_CODE_SUBAGENT_MODEL": "gemini-3-flash"
  }
}

Step 2: Set Environment Variables

macOS/Linux (zsh):

echo 'export ANTHROPIC_BASE_URL="http://localhost:8080"' >> ~/.zshrc
echo 'export ANTHROPIC_API_KEY="test"' >> ~/.zshrc
source ~/.zshrc

macOS/Linux (bash):

echo 'export ANTHROPIC_BASE_URL="http://localhost:8080"' >> ~/.bashrc
echo 'export ANTHROPIC_API_KEY="test"' >> ~/.bashrc
source ~/.bashrc

Windows (PowerShell):

Add-Content $PROFILE "`n`$env:ANTHROPIC_BASE_URL = 'http://localhost:8080'"
Add-Content $PROFILE "`$env:ANTHROPIC_API_KEY = 'test'"
. $PROFILE

Windows (Command Prompt):

setx ANTHROPIC_BASE_URL "http://localhost:8080"
setx ANTHROPIC_API_KEY "test"

Step 3: Run Claude Code

# Make sure proxy is running
antigravity-claude-proxy start

# In another terminal
claude

Now you're using Claude Code with free Antigravity models!
