How to Use Codex for Free with Simple Setup

Getting access to Codex, the AI coding assistant, without spending a dime is easier than you think. This guide shows you how to set it up quickly and tap into its power free of charge.

Unlocking Free Access to Codex

Codex, the AI tool that helps with programming tasks, doesn’t have to break the bank. By following a few straightforward steps, you can start using it free of charge. The journey begins by choosing how you want to run Codex—either via a dedicated extension or directly from the ChatGPT website after setup.

To kick things off, you need to head to X Euro by searching for it on Google. Once there, be sure you’re logged in so you can explore the AI chat models available. Searching for “free” in the model list brings up all no-cost options, with the latest being model 23.8 max free.

Setting Up Your Codex Environment

The key to seamless use lies in properly configuring Codex with the right server details and your personalized API key.

Visit the documentation page and copy the base URL provided—that’s your gateway to Codex’s capabilities. Next, join the creator’s Discord community to access a simplified configuration template and detailed setup instructions. Inside the Discord, the resources channel houses the necessary config files, including the config.toml and auth.json templates you’ll need to customize.

Configuring Files and API Keys

Open your terminal and navigate to the Codex directory. In the config.toml file, replace any existing code with the new configuration copied from Discord. This includes pasting your base URL and the precise model ID for the free version. Give the configuration a clear name like “X Kiro” to keep it recognizable.

Next up is handling authentication. In the auth.json file, clear any previous contents and paste the new template from Discord. Then, generate a fresh API key on the platform, name it appropriately, and paste the key into the file. Saving these files finalizes your setup.

Making Sure It Works

Restart your VS Code editor to make sure everything reloads properly. For initial testing, run the Codex command line interface to confirm connections and responses. A simple test prompt like “hello” should deliver a smooth reply, signaling you’re ready to use Codex effectively.

From here, you can either continue with the CLI or opt to download the Codex desktop app version, which opens the chat window instantly without the need to log in again each time.
