when in chatgpt’s site and after giving a prompt to chatgpt the cpu spikes
my cpu [Ryzen 5 5600g] uses 100% of one of its six cores so my cpu usage gets to 15%-20%
i believe its this dot thats animating
because after its gone (done writing) the cpu usage goes back down

i just tried both chrome (my main browser) and FireFox and still same problem
my pc specs:
Ryzen 5 5600g
8gb ram
gpu integrated
i just tried disbling js and deleted some css, and its not the circle but it has to do with when hes thinking/ writing
the cpu usage is still high but the circle is gone
Can confirm, Firefox and Opera are spiking my CPU (Ryzen 9 3900X) on one Core while an answer is generated.

Same here with chrome, it even crashes the tab sometimes
Yes, I have that on my Windows PC with Chrome and on my iPhone also
¯_(ツ)_/¯
then what? no one from Open AI answers to this? I am having the same issue and it is ridiculous. And after a minute or so of having my PC blocked, ChatGPT gives no answer anyway. I am a paying customer
it really annoying when it freezes then sometimes sends an error
I can confirm I have the issue too, on Windows 11 and Firefox, both up to date.
I have the same issue on my mac.
It seems that chatGPT is taking my system resources while generating an answer…
Same here, the computer gets sluggish and chatgpt very laggy.
I’m experiencing the same issue here. It takes longer to respond each time, and the fan on my laptop starts running at full speed.
I Have feeling, that instead of using cloud resources of OpenAI only, they started to use and our CPUs…
Any secret experiments about local device based AI, like Apple Intelligence?
Ohh, by the way, exactly the same is with the desktop application…
How to Resolve High CPU Usage on ChatGPT
I’ve found a way to fix the frustrating issue of high CPU usage when using ChatGPT on my computer. While this method isn’t ideal, it’s a quick and effective workaround until an official solution is released.
-
When you notice the ChatGPT website slowing down on your computer, open the ChatGPT mobile app on your phone.
-
Input your new prompt on the mobile app. The mobile version seems to generate responses without the same performance issues, likely because it doesn’t utilize local device resources in the same way the desktop version does.
-
Once the mobile app finishes generating the response, return to your computer’s browser.
-
Perform a hard refresh on the ChatGPT page. This will instantly load the new response from your mobile session, bypassing the sluggish generation process on your desktop.
A hard refresh forces your browser to reload all content directly from the server, which can be useful for resolving display issues. To do this, use the following keyboard shortcuts:
-
For Windows: Press Ctrl + F5 or Ctrl + Shift + R.
-
For Mac: Press Command + Shift + R.
This method has been the only one that has worked consistently for me. I hope it helps you too!
This has gotten unbearable lately after GPT5 eeek!

Very high CPU usage and making overall system very sluggish. Anyone from openAI has solution for this ?
I have been experiencing this exact issue since the release of GPT-5. My fix has been to duplicate or switch to a different tab and start over. When I open the chat, the response is present while the other tab is still loading,
I guess that when it tries to render the text, there are some issues with performance there. I am going to investigate more
I am facing the same issue…waiting for a quick solution from the OpenAI team.
I started facing this issue with GPT5, any tips?
