I would like to request a feature for the Codex CLI.
When a user specifies an invalid model via the --model flag, it would be very helpful if the CLI could list all available valid models, similar to how cursor-agent behaves.
Example of desired behavior:
❯ codex --model test
Cannot use this model: test. Available models: model-a, model-b, model-c...This improves discoverability and user experience.
