Yea absolutely. I am using GPT 5.2 / 5.2 Codex with OpenCode and it just doesn't get what I am doing or looses context. Claude on the other side (via GitHub Copilot) has no problem and also discovers the repository on it's own in new sessions while I need to basically spoonfeed GPT. I also agree on the speed. Earlier today I tasked GPT 5.2 Codex with a small refactor of a task in our codebase with reasoning to high and it took 20 minutes to move around 20 files.
I don't know any reason to use 5.2, when 5.3 is quite a bit faster.
If using OpenAI models, use the Codex desktop app, it runs circles around OpenCode.
Can you educate me as to what makes Codex app superior using the same GPT model in both? Thx in advance!
