Google has completely revamped the way that AI usage is measured and metered out across the various tiers: Free, AI Plus ($8/month), AI Pro ($20/month), and AI Ultra ($100 or $200/month). Google now measures Gemini AI usage by the computing power requirements of your requests, not by the number of requests you make. So, whereas before you might have been able to generate three videos a day, now you might find you can generate only two if the videos are particularly complex. It makes more sense from Google's perspective, because it's measuring how much you're actually costing the company and its data centers in terms of resources. However, it's all a bit vague for end users, who are now less sure about when they'll hit their limits. The two main factors that go into how much AI you can use are the plan you're on, and the complexity and length of your prompts. Google says in its support docs that "access is subject to change or may be limited based on testing, experimentation or availability."
