Were you looking at another comment? I had to reread what I wrote, and I can't understand where you'd get the impression that I use it that much. I don't even use it daily (looking at my stats, it seems I used it less than every other day).
gpt5.4 pricing per million tokens is Input: $2.50 Cached input: $0.25 Output: $15.00
I tried re-running a rather long code review request I had lying around, and gptel says it spent 2.2k tokens; I don't know if that's input or output or what, but if we say it's output since that's the most expensive, then that single review cost me just $0.033.
I know about the prices and that's why I wondered how you could possibly give an answer to these questions. But now I'm just wondering why you felt compelled to answer here when OP specifically asked about day-to-day AI use and agentic workflows and you seem to have experience with neither.
