Did you receive a voucher for the Codex track of the hackathon and don't know where to redeem it? You're not alone. Many teams add credits and then discover the Codex model doesn't show up or the API returns "voucher access denied". Frustrating, right? Let's unravel this mystery step by step.
What's going on
The OpenAI Codex Track prize requires you to use Codex as a coding agent. Hugging Face and the organizers handed out vouchers so you can try and build with Codex. However, there are two key points that often cause confusion:
- Vouchers can be coupons you redeem on the OpenAI platform or credentials that organizers enable on an organizational account.
- Codex isn't always enabled by default on every account or org. Even if you have credits, the model might require explicit activation.
The result? You have credit, but not permission to use the model. Annoying? Yes. Fixable? Also yes.
