The 5-hour usage limit for ChatGPT Plus has been reinstated, and it appears the latest model, GPT-6 Astra, depletes the quota much faster than previous versions.
Imagine this: You finish work, turn on your screen, and decide to hand over your backlog to ChatGPT. Just as you get motivated and think, “Alright, let’s get started,” an alert window suddenly pops up saying, “You’ve reached your usage limit.” Already? I just started! This absurd situation is happening frequently among recent ChatGPT Plus users.
Why does this matter?
It is easy to expect ChatGPT Plus, a paid service we pay $20 (approx. 28,000 KRW) for every month, to be “unlimited” Source: Which AI to choose in 2026. Comparing five neural networks ChatGPT, Gemini, Grok, Deepseek, and Qwen. However, as usage limit policies have recently tightened, it is causing significant disruptions to practical work efficiency. This is a particularly sensitive issue for users who frequently utilize high-performance models. We now live in an era where we must strategically manage our usage, much like managing a data plan, even when using AI.
Understanding it easily
ChatGPT Plus’s usage limit is similar to a “theme park unlimited pass.” You paid the admission fee, so you might think you can ride as much as you want, but for popular rollercoasters (high-performance AI models), the system subtracts a “ride ticket” each time you board.
Recently, OpenAI reinstated a “5-hour usage time limit” for ChatGPT Plus subscribers when using certain tools Source: OpenAI reinstated the 5-hour limit for ChatGPT Plus — it… / Habr. On top of this, separate weekly quotas (the maximum amount available to use) are also being managed Source: OpenAI reinstated the 5-hour limit for ChatGPT Plus — it… / Habr.
In particular, the newly introduced “GPT-6 Astra” model consumes far more computational resources (the computer’s processing power) than the previous model, “Sol,” because of its superior performance. Users are complaining that this 5-hour quota runs out in just 13 minutes Source: ChatGPT Plus 5-hour quota burns out in 13 minutes on…. Sometimes, 30% of the entire weekly quota disappears in an instant after just a few simple questions Source: ChatGPT Plus 5-hour quota burns out in 13 minutes on…. Metaphorically, it is like taking a high-end sports car to a convenience store down the street and finding that the gas tank is already half empty.
Current situation
OpenAI has confirmed that the usage of the GPT-6 Astra model is being depleted much faster than previous versions Source: ChatGPT Plus 5-hour quota burns out in 13 minutes on…. Users are paying a non-trivial $20 per month to use high-performance AI, but they are still facing a reality that is far from “unlimited” Source: Which AI to choose in 2026.

What will happen in the future?
As AI technology advances, the computing cost (processing cost) per question is not decreasing; rather, it is increasing as the models perform more complex tasks. If users continue to desire only “smarter models,” this quota depletion problem is likely to continue. For users, the “AI utilization ability” to selectively use lighter models for some tasks and high-performance models for others, depending on the nature of the work, will become even more important.
MindTickleBytes AI Reporter’s View
Technological progress demands higher computing resources. The stringent limits introduced by OpenAI paradoxically show that current AI models come at a much greater cost than we imagine. Subscribers are now at a point where they need to consider how to wisely allocate “limited resources.”
