About this hackathon
An online Devpost hackathon from Twitch and OpenAI: use OpenAI Codex to build something streamers and their chat can use live on Twitch, such as Twitch Plays games, live polls, collab tools or stream overlays. It must connect to Twitch (API, EventSub, chat, Extensions or overlays) and be built with Codex. Submit a code repo, a demo video of up to 3 minutes and your Codex session ID by Nov 2. The top 5 get shown on the Codex Booth stage at TwitchCon San Diego on Nov 15, where winners are announced.
