GPT-4.1 and o4-mini are going to be full 1 use/credit… 
Neither choice feels correct to me. 4.1 is not bad (feels pretty snappy), but nowhere near Gemini 2.5 Pro or Sonnet 3.7 which all cost 1 credit. o4-mini high is pretty capable, but pricing it now at 1 credit, when o4-mini costs exactly the same in API as o3-mini, which costs third of a credit/use is … rather terrible. Cost update for GPT-4.1 and o4-mini
I am working on updating the table.
I kinda liked both models (though o4-mini today was so slow, like 5 minutes to change 3 lines…). But neither is worth 1 credit in my opinion.
