You mentioned needing 40k tiles and renting a H100 for 3$/hour at 200tiles/hour, so am I right to assume that you spend 200*3=600$ for running the inference? That also means letting it run 25 nights a 8 hours or so?

Cool project!

Yup back of the napkin is probably about there - also spent a fair bit on the oxen.ai fine-tuning service (worth every penny)... paint ain't free, so to speak
