Yes Sora hallucinates significantly more than Claude.
I find that Codex generally requires me to remove code to get to what I want, whereas Claude I tend to use what it gives me and I add to it. Whether this is from additional prompting or from manual typing, i just find that codex requires removal to get to desired state, and Claude requires adding to get to desired state. I prefer adding incrementally than removing.
Sora 4.5 tends to randomly hallucinate odd/inappropriate decisions and goes to make stupid changes that have to be patched up manually.
