<AgentIntro agentName="Codex" agentMarketingUrl="https://openai.com/codex" />

  1. Open your `~/.codex/config.toml` file.

  2. Add the following to the start of the file:

     ```toml highlight={1,7} theme={null}
     model = "<FRIENDLIAI_MODEL_ID>"
     model_provider = "friendliai"

     [model_providers.friendliai]
     name = "FriendliAI"
     base_url = "https://api.friendli.ai/serverless/v1"
     experimental_bearer_token = "<FRIENDLIAI_API_KEY>"
     ```

     Replace the following placeholders:

     * `<FRIENDLIAI_API_KEY>`: Your FriendliAI API key.
     * `<FRIENDLIAI_MODEL_ID>`: The FriendliAI model ID. For example, `zai-org/GLM-5.2`.

  3. Save your file.
