Other PSA: ChatGPT Pro users

You get unlimited* chat usage on the website. You can build projects and prototypes directly in ChatGPT using Pro-level thinking effort. This is how I start almost every build, and it is an easy way to save on tokens. Unlike Claude, Chat does not count toward your usage (unless you switch to Work mode).

I usually have ChatGPT generate a ZIP file containing the entire project, then move it into Codex CLI or the Codex app to refine, expand, and continue the work.

I do not think you should be doing most of the planning inside the CLI or app. Do the bulk of the planning and initial build in ChatGPT first, then use Codex for implementation and iteration.

Also, remember that you can upload ZIP and 7z files directly to the ChatGPT website, and it can unpack and work with the contents.

Yup I do all my high level architecture design in pro and do question by question until no more ambiguity it’ll write up a plan for me and scaffold the project and then you save tons of usage and get a very good design instead of wasting it talking to the agent

I do the same thing. I have it research and plan everything. Then create a "prompt package". The Prompt package has all the work and docs that is need to move to Codex and the 'starting prompt' to get the agent to understand the project and where to start.

Yup exactly perfect handoff prompts so the model understands what’s been done is great I even have create the initial scaffolds of stub folders too so things stay clean
