Codex with V0 unauthorized

What version of Codex is running?

0.1.2505172129

Which model were you using?

v0-1.0-md

What platform is your computer?

darwin | arm64 | 24.5.0

What steps can reproduce the bug?

Prerequisites:

• Vercel v0 Pro Plan: I have an active Vercel v0 Pro subscription.
• ChatGPT Organization with Credits: My OpenAI account is part of an organization, and it has sufficient credits.

1. Ensure you have a Vercel v0 Pro plan.
2. Ensure your OpenAI account is part of an organization with available credits.
3. Follow the setup instructions for "v0 in OpenAI Codex CLI" from the Vercel documentation: https://vercel.com/docs/v0/codex
4. Attempt to run a command that utilizes a v0 model through the OpenAI Codex CLI. codex --provider vercel --model v0-1.0-md

What is the expected behavior?

I expect to be able to successfully run and interact with Vercel v0 models via the OpenAI Codex CLI, given my active v0 Pro plan and available OpenAI organization credits. Specifically, I expect the CLI command to:

Successfully authenticate with the Vercel v0 API (via the V0_API_KEY).
Initiate a request to the v0-1.0-md model hosted by Vercel.
Return a response from the v0 model without any "Unauthorized" errors.

What do you see instead?

Error Message:

 ⚠️  OpenAI rejected the request. Error details: Status: 401, Code: unknown, Type: unknown, Message: 401 "Unauthorized". Please verify your settings and try again.
