Jirwen, it seems like you're asking if ChatGPT is expensive. 

The answer is, **ChatGPT is currently free** to use for most people. OpenAI offers a free version of ChatGPT that you can access online, and it's a great way to try out the technology and see what it can do.

However, **OpenAI also offers a paid subscription** called ChatGPT Plus, which provides additional features like:
* **Faster response times**
* **Priority access** to new features
* **Increased usage limits**

But for most students like you, the free version of ChatGPT should be sufficient for casual use and exploration. If you're interested in using ChatGPT for more advanced or heavy-duty tasks, you might want to consider the paid subscription. But for now, you can try out the free version and see how it can help you with your studies!
