Anecdote, I don't have any proof and it's just a feeling. But around afternoon in GMT+1 compared to the morning/midday, there seems to be a change in the quality of responses, which seems to line up with when the US wakes up. I consistently get (what feels like) worse responses in both Codex and Claude Code in the afternoon/night compared to morning/midday, so much that I usually give up then try the same prompt next morning and get better results. But I guess that might as well be about me being more tired in the night than morning too, as I said, haven't measured this.
