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, because so far it seems to be working EXTREMELY well, arguably even better than when I use gpt 5.4 on Codex itself. It has made massive edits in 1 response and since it tests everything in it's own python environment for the website, there are almost NEVER any bugs/issues. I basically just discovered I could do this, and it is just crazy to me how powerful it is when my normal instinct is "its a chatbot powered website so it can't do it like Codex cli/ide-plugins can" but it genuinely can.
I assume most people already are aware of this, but if anyone has had the instinct like I had and has simply never thought of tasking the website chatbot with large agentic tasks using zip files, I encourage you to try it with 5.4. Even the projects section has a 20-file cap for individual projects which I would always upload individual code files to, but there is no reason to do all of that at all when you can just zip up the ENTIRE project with thousands of files and upload it to a normal chat and get the entire .zip file back in one piece.
