yeah the json token counts are super misleading. i run a bunch of claude agents for automation and like 85% of input tokens end up being cached reads -which cost 1/10th of the sticker price. so your $200k number is probably closer to $25-30k in real cost, and thats before you factor in that anthropics own infra is way cheaper than retail API pricing. the $5k forbes number was always nonsense but even the "corrected" estimates in TFA are probably still too high IMO
