I built an open-source solution: <strong><a href="https://github.com" rel="noopener noreferrer">claude-gpt</a></strong> [1.1].</p> <p>This lightweight local proxy enables you to keep working in Claude Code after hitting limits by routing requests to GPT models via your existing ChatGPT subscription [1.1].</p> <h2> How It Works 🛠️ </h2> <p>By leveraging <code>ANTHROPIC_BASE_URL</code>, <strong>claude-gpt</strong> acts as an intermediary, translating complex Anthropic API calls into OpenAI formats [1.1].</p> <ul> <li> <strong>Model Switching</strong>: Use the <code>/model</code> command (e.g., <code>/model gpt</code> or <code>/model opus</code>) to switch seamlessly without restarting your workspace [1.1].</li> <li> <strong>Live Translation</strong>: Handles tools, system prompts, and streaming [1.1]. </li> </ul> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>[Claude Code] --► [claude-gpt proxy] --► [GPT / Claude] </code></pre> </div> <h2> ⚡ Quick Setup (Windows) </h2> <p>With Node.js (v18+) installed, run the following in PowerShell:<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight powershell"><code><span class="n">git</span><span class="w"> </span><span class="nx">clone</span><span class="w"> </span><span class="nx">https://github.com/hanjun-lin/claude-gpt.git</span><span class="w"> </span><span class="n">cd</span><span class="w"> </span><span class="nx">claude-gpt</span><span class="w"> </span><span class="o">.</span><span class="n">\install.ps1</span><span class="w"> </span></code></pre> </div> <h2> ⚠ Terms of Service &amp; Safe Mode 🛡️ </h2> <ul> <li> <strong>ToS Alert</strong>: Default usage involves accessing OpenAI’s internal Codex backend, which carries potential account risk [1.1].</li> <li> <strong>Official API Option</strong>: Set <code>GPT_PROXY_BACKEND=openai</code> and provide your <code>OPENAI_API_KEY</code> to use the official, compliant API [1.1].</li> </ul> <h2> Feedback &amp; Contributions 💬 </h2> <p>Check out the code, contribute, or open an issue on GitHub.</p> <p>👉 <strong><a href="https://github.com/hanjun-lin/claude-gpt" rel="noopener noreferrer">Check out the GitHub Repo here</a></strong> [1.1]</p>
