Differences between github-copilot/gpt-5.3-codex and openai-codex/gpt-5.3-codex
I'm trying out the Codex Pro plan as i migrate away from Github copilot in prep of the changes coming June 1st and I'm noticing some differences.
The key one being codex's version of 5.3-codex seems more hesitant to actually make code changes, it just tells me it's going to begin implementation but then the turn just stops. When i prompt it that it can proceed, it does the same behaviour. If i run the same prompt using github's 5.3-codex, it reads the proper files and then just started editing/writing.
has anyone else experienced these kinds of differences with the same model but different provider?
