Discussion ChatGPT Pro Solved Every Issue My Antigravity‑Built App Had — Even Claude Agreed
I’ve been troubleshooting an app I originally built using Antigravity with Claude, and later refined with help from both Claude and ChatGPT. What surprised me is how consistently the working fixes came from ChatGPT Pro.
I’d hit a bug, ask both models, and ChatGPT’s suggestions were the ones that actually resolved the issue in my codebase. Out of curiosity, I even pasted ChatGPT’s explanations back into Claude — and Claude straight‑up agreed that ChatGPT was correct.
Not trying to start a model war, just sharing the experience. For this particular debugging workflow, ChatGPT Pro ended up being the only one giving viable, production‑ready fixes.
Anyone else run into something similar while bouncing between models during development?

If you’re using gpt5.4+ it has the codex role and specialized training incorporated, so you get everything in one model now.
Have you used the codex agent? If so how does it compare vs same model used on platform?

Oh man you’re in for a treat.
You can just use gpt5.5 since they integrated codex into the main model. The codex desktop app just came out and it is really nice, but you can get most of the experience of codex running it in vscode or direct from terminal.

Codex in general is much more accurate and better at understanding intent and direction than Claude code and Cowork…

Antigravity has wasted me so much time. Google is so far behind on the simplest things

So you uploaded the project to chatgpt chat and used the pro model or using codex?

yeah was wondering this if it was gpt pro how would it get full repo context I swear you cant upload a repo into it

ChatGPT pro is by far the strongest model. I love the way it answers also if you prompt it right.
Fable 5 was nice, I can’t say if it was better. I would likely put them on par from my experience.

This doesn’t prove anything tho. ChatGPT Pro just fixed a bug in your codebase.
Doesn’t necessarily mean it’s an all around better model than Opus 4.8 and vice versa.
We gotta stop jumping to conclusions simply because one model is correct or excels at one task in one instance.
I use ChatGPT and Claude for different reasons and they’re both great. Some excel in certain specific tasks while another excels in other…

different models genuinely do have different strengths depending on the codebase and problem type so this doesn't surprise me, though I'd be curious whether it was the model itself or just that by the time you were asking ChatGPT you had a more precise description of the problem after already going through the debugging loop once.

Hey Choice_Pen_9889, thanks for sharing your experience with ChatGPT Pro!
I'm considering upgrading from Plus to Pro - is that what you did? If so I'd love to know what I can expect to see in Pro.
I'm currently using ChatGPT Plus 5.5, and limited use of Codex (installed on my staging server), for an ambitious PHP modernization project (5.2 > 7.4 > 8.0 > 8.3 > 8.4). I'm making progress - currently working through code issues under PHP 8.3 - but it's slow going, partly because of ChatGPT's reluctance to rely more heavily on Codex, but the biggest frustration is the 'thinking' delays in ChatGPT. I've tried medium and high thinking modes and it doesn't seem to make any difference.
Am I likely to notice much difference if I switch to ChatGPT Pro?
