ChatGPT Sites Hackathon

Here's a midweek plan for the builder crowd: a hackathon centred on ChatGPT Sites, with the challenge revealed only at kick-off. You pick a track — ChatGPT Work or Codex — and get hands-on building, with pizza and drinks thrown in to keep the energy up.

It runs on Wednesday 2 September 2026, from 5.30pm to 9.30pm. Best part? It's free. Even better if you're joining via phone — the ChatGPT Work track is mobile-friendly, so no laptop required if that's your style.
