model 4o payed subscription: I just uploaded a (relatively small) android strings.xml and very detailed instructions what to translate and what not (Tags) and objective to try to not lengthen the texts (shorter or same). It said it would take about 30-45min. After over 1.5 hours it gave me a file with 5 lines.
I will now convert to the usual method: never post more than maybe 10 lines because it just cannot handle lots of text. It will come with all kinds of excuses why 1,5 hours is not enough for 200 lines of english to polsky.
