Did you guys know you can have GPT do full agentic editing of a project on the ChatGPT website using .zip files?

I'm not sure how I had never thought of doing this, but with GPT 5.4, for example if I am trying to fix/develop a plugin for anything but my Codex credits are low (plus account), I can just zip up the entire folder (the limit is 512 MB, which is more than enough for basically everything), upload the zip itself to the website, and tell it what to do EXACTLY like I would in codex, and it will spend upwards of 10+ minutes working on it and providing the full .zip file back. It is pretty wild to me,
