🎯 Claude Code Free – OpenCode Zen + Minimax M2.5 (No GPU, No Region Lock)

Hey everyone! Welcome back to PakAlerts. Today I'm going to solve a problem that many of you have been facing – how to use Claude Code for free without hitting a wall.

You've probably seen videos telling you to use Nvidia NIM or run local models with Ollama. Let me be honest with you – neither of those methods is working well for most people anymore. Nvidia NIM has become too slow during peak hours (after 6 PM IST, it's almost unusable). Plus, many countries can't even verify their Nvidia accounts. And Ollama? Unless you own a ₹4 lakh MacBook Pro with 64GB RAM, forget about running intelligent models at a usable speed. Even then, the fast models are dumb, and the smart models are painfully slow.

So what's the real solution? I recently discovered a method that changed everything – and I want to give a huge shoutout to one of our subscribers, Rishabh Verma, who told me about this. You can now use OpenCode Zen with the Minimax M2.5 model – completely free, globally available, no region restrictions, no phone verification, and it works on any laptop. And the best part? It runs inside Claude Code CLI, inside OpenCode, and even directly inside VS Code.

In this guide, I'll walk you through everything like we're sitting together. No copy‑paste from other tutorials – just what actually works, step by step.

🎁 Credit where it's due: This OpenCode Zen method was shared by our subscriber Rishabh Verma. Thank you, Rishabh! Because of you, thousands of developers can now code for free.

🤔 Why This Method Works Better Than Nvidia NIM & Ollama

• No region lock – Works anywhere in the world. No phone verification needed.
• No GPU required – The model runs in the cloud. Your laptop just needs a terminal.
• No peak hour slowdowns – Nvidia NIM becomes unusable after 6 PM. OpenCode Zen stays fast.
• Minimax M2.5 is Opus‑level – Benchmarks show it's comparable to Claude Opus 4.6 and Sonnet. This is not a toy model – it can handle real production coding.
• Works in multiple interfaces – OpenCode CLI, Claude Code CLI, and VS Code extension.
• Soft limits only – No hard daily caps. Limits adjust automatically based on traffic.

📊 Minimax M2.5 Benchmarks: Go ahead – search "Minimax M2.5 vs Claude Opus 4.6" on Google. You'll see it performs at Opus level. In my Claude Code Pro plan, I almost only use Sonnet because Opus burns through my quota in 4 messages. These open‑source models sit at Sonnet‑to‑Opus range – perfect for large projects.

📋 What You'll Need

• A computer (Mac, Linux, or Windows – old laptops work fine).
• A free OpenCode Zen account (no credit card).
• VS Code installed (if you want the GUI experience – optional).
• About 15 minutes of patience.

🔑 Step 1: Get Your Free API Key from OpenCode Zen

This is the only account you'll need. No phone verification, no billing setup.

1. Go to the OpenCode Zen website (link available in this article's resources).
2. Click on "Zen" in the navigation, then click Login – sign up with Google or email.
3. After logging in, do not enable billing. We only use free models.
4. Go to the API Keys section (usually in settings or dashboard).
5. Click Create an API Key. Give it any name – say "claude-code".
6. Click Create. The key will appear. Copy it immediately and save it somewhere safe (you won't see it again).

That's it. Your free API key is ready. For security, after completing this tutorial, you can always delete this key from the dashboard.

💻 Step 2: Install Claude Code CLI (Mac & Linux – also works on Windows via WSL)

Important: Even if you only want to use Claude Code inside VS Code, you still need the CLI installed first. The VS Code extension depends on it.

• Open your terminal (iTerm2, Mac Terminal, or Linux terminal).
• Go to the official Claude Code website and copy the installation command.
• Paste it into your terminal and press Enter.
• Wait for the installation to finish.
• To verify, type: claude --help. If you see a help menu, it's installed correctly.

📦 Step 3: Install OpenCode (Mac & Linux)

OpenCode is a CLI tool similar to Claude Code, but open source. We'll use it to test the free model first.

• Go to the official OpenCode website – you'll see an install command.
• Copy the command and paste it into your terminal. Press Enter.
• After installation, restart your terminal.

🧪 Step 4: Test the Free Model in OpenCode (Quick check)

This step is optional but recommended – it confirms your API key works.

• In your terminal, type: opencode and press Enter.
• The OpenCode interface opens. Type /connect and press Enter.
• Select OpenCode Zen from the list.
• Paste your API key when prompted and press Enter.
• You'll see a list of free models. Select Minimax M2.5 Free.
• Now ask: which model are you? – it will respond in seconds. See how fast it is? No waiting, no errors.
• Press Ctrl+C to exit.

⚙️ Step 5: Configure Claude Code CLI to Use the Free Model

Now we tell Claude Code to use OpenCode Zen's API instead of Anthropic's paid endpoint.

• Open your terminal and type: code ~/.claude (this opens the Claude config folder in VS Code – make sure VS Code is installed).
• Inside the .claude folder, look for a file named settings.json. If it doesn't exist, create it.
• Add the following configuration (you can copy from the resources section):

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://opencode.ai/zen",
    "ANTHROPIC_MODEL": "minimax-m2.5-free",
    "ANTHROPIC_API_KEY": "YOUR_API_KEY_HERE",
    "ENABLE_TOOL_SEARCH": "true"
  }
}

• Replace YOUR_API_KEY_HERE with the API key you copied from OpenCode Zen.
• Important: If you already have a settings.json with existing settings, do NOT overwrite it. Only add the "env" block inside the curly braces after your existing configuration.
• Save the file and close VS Code.

🚀 Step 6: Launch Claude Code with the Free Model

• In your terminal, type: claude and press Enter.
• Choose your theme (Dark or Light).
• Claude Code will detect the custom API configuration and ask: "A custom API configuration was found in your settings. Do you want to use it?" – say Yes and press Enter.
• Press Enter again to confirm.
• Now type /model and press Enter. You'll see Minimax M2.5 Free listed. Select it.
• Type hey – you'll see the response almost instantly. Congratulations – you're running Claude Code completely for free!

🖥️ Step 7: Run Claude Code Free Inside VS Code (Mac/Linux)

If you prefer a GUI over the terminal, this is for you.

• Open VS Code.
• Go to the Extensions tab (Cmd+Shift+X). Search for "Claude".
• Find the extension named Claude Code for VS Code by Anthropic (look for the verified tick mark). Install it.
• After installation, open any project folder or a file.
• You'll see a Claude Code icon in the sidebar – click it. Alternatively, right‑click in the editor and select "Open Claude Code".
• Click New Session.
• Type /model, press Enter, and select Minimax M2.5 Free.
• Type a test message – you'll see the AI reply inside VS Code. Your free setup is now working beautifully.

🪟 Windows Setup (Complete Guide)

Windows users, don't worry – you're not left out. The process is straightforward, but you'll need to install Node.js and Chocolatey first.

Step 1: Install Node.js via Chocolatey

• Search for PowerShell, right‑click, and run as Administrator.
• Go to the Chocolatey website, copy the install command, paste it into PowerShell, and press Enter. This installs Chocolatey.
• Close that PowerShell window and open a new one as Administrator again.
• Install Node.js by running the command from the Chocolatey website (usually choco install nodejs). Type Y when asked.
• Close PowerShell and open a normal PowerShell (non‑admin). Type node -v to confirm installation (you should see a version like v24).

Step 2: Install OpenCode and Claude Code on Windows

• In PowerShell, run: npm install -g opencode-ai to install OpenCode.
• Then install Claude Code: go to the official Claude Code website, click Documentation → Quick Start, copy the PowerShell install command, paste it into PowerShell, and press Enter.
• If the claude command is not recognized, you'll need to add the npm bin folder to your PATH. Search for "Environment Variables", edit the Path variable, add C:\Users\YourUsername\AppData\Roaming\npm, and click OK. Then open a fresh PowerShell window.

Step 3: Configure settings.json on Windows

• Open File Explorer and go to: C:\Users\YourUsername\.claude\. If the .claude folder doesn't exist, create it.
• Create a file named settings.json inside that folder. Open it with Notepad.
• Paste the same configuration shown above (with your API key). Save the file.
• Now type claude in PowerShell – it should work. Follow the same steps as on Mac: select theme, accept the custom config, choose Minimax M2.5 Free, and test.

Step 4: Run in VS Code on Windows

• Download and install VS Code from the official website.
• Install the Claude Code for VS Code extension (same as on Mac).
• Open a folder, click the Claude Code icon, start a new session, select Minimax M2.5 Free, and you're done.
