I can't use $20 of credit (gpt-5 thinking via intellij's pro AI subscription) a month right now with plenty of usage so I'm surprised at the $1k figure. Is Claude that much more expensive? (a quick Google suggests yes actually).

Having said the above some level of AI spending is the new reality. Your workplace pays for internet right? Probably a really expensive fast corporate grade connection? Well they now also need to pay for an AI subscription. That's just the current reality.
