OpenAI quietly launched a showcase for the best Codex and ChatGPT use cases

You can filter by product, by the kind of work, or by author, and the examples range from building an interactive quiz with built-in analytics to editing a finished video in DaVinci Resolve entirely through Codex.

GPT-5.6 Sol does the heavy lifting on curation, scanning X for the most useful posts, while a developer still reviews what actually makes it into the feed. Every card links back to the original post, so you get the full context instead of a stripped-out quote.

The platform is openly labeled “work in progress,” and it shows in places — but the idea holds up. Instead of digging through X for inspiration, you can just browse what other people have already figured out. For anyone squeezing real work out of Codex or ChatGPT, this is a genuinely useful cheat sheet, not another marketing landing page.
