Use the following values:

Important: Use the exact API base URL ending with /api/v1. If the base URL is wrong, Codex CLI calls will fail or target the wrong endpoint.

Verify in Codex CLI

Run a simple prompt to confirm Codex CLI is using the configured provider.

Run a Test Prompt

codex "hello"

You should see a normal response and model metadata in the session header.

Optional Follow-Up Prompt

Try another prompt such as Explain this codebase to validate ongoing interaction quality.
