How did you end up with only $40 in API cost despite using AI daily?
[–] internet_points 2 days ago
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.

OP said "I'm curious how people on HN are using AI day to day" and I gave an honest answer. If the answers were only from those using agentic setups daily, that would give a skewed picture. (And I do have some experience with agentic coding, but for now I'm staying away from it; mainly because I don't trust it with my data and I can't quite justify the cost of a local setup.)

But before this thread gets too deep, maybe you want to ask https://news.ycombinator.com/item?id=50376720 why they feel compelled to answer here. Or https://news.ycombinator.com/item?id=50375782 . Or https://news.ycombinator.com/item?id=50367460 . Since you were wondering.
