Or it’s a different quant, or the initial pricing included a big surcharge for the lack of anything even roughly comparable at the time (similar to o1, which probably wasn’t different in size from 4o or o3 despite almost an OOM cost difference), or they used to objectively lack hardware to serve it and the price reflected that
