Roo Code

Roo Code officially supports the OpenAI Compatible provider, so it can connect to this service directly.

1. Install

Official install page: https://roocode.com/extension

If you use VS Code or a compatible fork, a direct install path is:

code --install-extension RooVeterinaryInc.roo-cline

You can also install the official Roo Code extension from the editor's extension marketplace.

2. Open provider settings

Open the Roo Code settings panel and go to model provider configuration.

3. Enter connection details

Set API Provider to OpenAI Compatible, then fill in:

• Base URL: https://codex.openai.com/v1
• API key: your codex_... or sk-... key
• Model ID: gpt-5-codex-mini

If the model is not listed in the dropdown, enter the model name manually.

4. Verify

Save the settings and start a new task to confirm Roo Code can connect and respond normally.
