Participants in a hackathon are encountering difficulties activating their OpenAI Codex vouchers. Many are struggling to find a method to input the Codex key, leading to denied access for the associated challenges. This issue has raised questions about how participants are expected to utilize their credits for these competitions.

One such challenge offers a dedicated prize track totaling $10,000 in cash and ChatGPT Pro subscriptions for the top three builds. Uniquely, Codex itself serves as the judge, evaluating entries based on the effective use of Codex and the overall quality of the submitted "Space."

To participate in this challenge, individuals must build a "Space" using Codex as their coding agent. The code then needs to be pushed to a public GitHub repository, ensuring it includes Codex-attributed commits. Finally, the repository link must be added to the "Space" README to complete the entry.
