Build a Twitch chat game, overlay or bot with Codex by Nov 2 at 2:00 PM PT (5:00 PM ET) and enter for $25,000. The hackathon page says "OpenAI and Twitch are teaming up," and the FAQ says "Use the free version of Codex."

What changed#

Devpost posted the Codex x TwitchCon Hackathon "with @TwitchDev and @OpenAIDevs is live!" at 1:00 PM ET on Friday, Oct 23. The rules pay $10,000, $6,000 and $4,000 for the top three and $2,500 to two runners-up, each with "stage time at TwitchCon." Sponsor: Amazon Advertising LLC. Administrator: Devpost. The page showed 802 participants at 5:57 AM ET.

Why it matters#

Our read: a dated, paid reason to ship a first Codex project. The FAQ answers "Do I need to be a developer?" with "No." Per the rules, it "must be an interactive experience that connects to Twitch, for example through chat, a stream overlay, the Twitch API, EventSub or an Extension."

How to use it#

Per the rules and FAQ:

Click Join Hackathon on the hackathon page.
Start from Twitch's Example Chatbot guide; templates are allowed.
Build in Codex, then "Type /status in the Codex thread where you built most of your project" and copy the session ID.
Submit a repo link, how you used Codex, and a YouTube demo "less than three (3) minutes" (unlisted OK).
Click Submit: "A saved draft is not entered."

Starter prompt (ours, untested):

Build a small Node.js Twitch chatbot starting from Twitch's Example Chatbot guide. When a viewer types !roll, reply in chat with their username and a random number from 1 to 20. Read the client ID, secret and tokens from environment variables, never commit them, and write a README with setup steps a judge can follow.

Good to know#

Skip Extensions this late: the FAQ puts review at 5 to 14 days and says "judges can't install an unreviewed Extension."
"Projects must be newly created during the Submission Period," per the rules.
Free Codex "has limits," so leave "headroom for final fixes before the deadline," per the FAQ.
Judging dates disagree: rules Nov 5 to 15 vs schedule Nov 3 to 6. Both put winners Nov 15 at TwitchCon San Diego.

Last checked: Oct 26, 2026, 5:57 to 6:05 AM ET. What changed: first published Oct 26; no updates since.
