Using ChatGPT for Planning vs Codex?

OpenAI Developer Community June 6, 2026

Good day.

First, I’d like to say that Codex has become such an incredible, powerful tool. I hardly write code anymore - what a paradigm shift! It’s remarkable to look back and recall how seamlessly we have transitioned.

Naturally, cost and power intertwine. We spend moar, and/or strategize to reduce cost.

As a result, I have been using ChatGPT w/ GitHub connector to plan and debug, while using Codex to execute, and have been wondering if anyone else has done so?

Advantages

  • Doesn’t cost Codex credits
  • Is much easier for back-and-forth
  • Can be used in any typical conversation

Disadvantages

  • I imagine the model isn’t as suitable as Codex, and more likely to make bad decisions? However, I haven’t really been able to notice any difference

Wonder if anyone else has adopted this strategy, and what they’ve seen.

I imagine this would be effective for many use-cases - not strictly coding.
