Why do some AI tools have a monthly limit on usage, like Uber's $1,500 cap?

It's mostly about managing server costs and preventing misuse. Running powerful AI isn't cheap. Every time you ask a question or generate an image, powerful computer chips in a data center are working hard. That costs the AI company real money in electricity and hardware. A monthly limit, like the $1,500 cap Uber reportedly set for its developers, acts like a safety valve. It stops a single user or a buggy script from accidentally racking up a bill that could sink a project. Think of it like a spending limit on a company credit card. The card works, but you can't buy a car with it. These caps are common, even if you don't see them. ChatGPT Plus has rate limits, meaning you can only send so many messages in a few hours. Image generators like Midjourney give you a set number of 'GPU minutes' per month on their standard plans. Once you hit your limit, you wait until next month or pay more for extra credits. A useful tip: always check the 'fair use' policy or rate limit section before committing to a paid AI tool. A cheap plan that throttles your speed after 50 queries might be useless for a big project, while a slightly more expensive one with a clear, high cap could save you major headaches.
