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.
