I’ve had a problem for the 2nd day now that after every question ChatGPT 4.o freezes after a few lines and then I open a new window and reload the page and there is the full answer. Oh and it is terribly slow.
Anyone else have or had this problem?
I’ve tried and they don’t work: other browser, clear cookies, other model, GPT
Me too have this problem 
Seems that ChatGPT’s website is maxing out cpu usage and using up a lot of ram at the same time.
Not a new bug.
This thread shows it appeared at one point quite a while back.
Check task manager, you should notice that for some reason the GPT tab in chrome / edge is using anywhere from 20% to 100% CPU usage.
Only thing we can do is bring it to their attention and await a fix.
Bump for more attention. This is happening to me right now. I use Opera GX and I noticed on the in-browser resource manager that my ChatGPT tab was somehow using 120gb of RAM on a 32gb machine.
Thankfully it’s as simple as closing and reopening the entire browser. But I’ve had a few responses quit generating mid response with this process. The wild thing is I can almost watch it generate live on the mobile app after prompting it through a desktop browser, while the desktop browser has to close and reopen lol. Please fix, I love this utility.
Same here!
How can I get it back to normal? I can’t keep closing and opening a new tab every 5 seconds!
May 2025 and the issue stills remains… My suggestion is that OpenAI uses the same system they use for billing - this one has no flaws whatsoever!!! In the meantime, I am still waiting for the bang for my buck and finally being able to work one entire day… It is worthless to try to follow the competition when you cannot solve your own old problems first.
I’m still facing that very problem, especially with o3 though, 4o works fine
I have a reasonably fast laptop and internet connection and have never had any performance issues with ChatGPT. but in the last 2 days I’ve spent hours trying to do things that would take minutes on chatgot. the window keeps freezing whenever i enter a query, especially if its realted to coding. Ive cleared my browser cache, acceleration, and all other recommended settings. any idea whats going on
exact same experience for me
You wrote this in May 2024, I am writing this on May 2025, Do we have to wait till May 2030 
Hey, guys from the OpenAI - are you kidding me, really? You are not still resolving this problem! May 2025. Why in this case do you charge me 20€ per month ? My chat always freezes, it is shame!
It’s so easy, Whatsapp and messanger use “lazyload”, it loads only minimum content and only on scrool (triggers the content) it should load another small piece of content, is ti so difficult?
same here. it get worse after moving to windows 11 freezing a lot.
Tell chat to compress all previous threads and store into memory. This completely fixed my issues
Please fix ASAP. It delays workflow considerably, on top of just being nerve wracking.
Any updates? It has no sense to pay if I need create new chat and lose context
hello my name is mair, sence the new chatgpt update i got, i had a bug in my chatgpt app, this image u can easy see, my chatgpt didn’t open work correctly, no metter if i reload the gpt or restart it, its just the same interface, and if i write something one the search bar and then press enter the message didn’t send even its start a new line but didn’t send a message, i have a video but i can’t upload on it, i hope this make me fixed
Same here. Unusable in every Browser. the first answer freezes the browser and the tab crashes, Same behavior in Chrome, Firefox ans Safari on an intel max on macos sequoia. Sadly there is no App for Intel macs what in itself is unacceptable. Now I have a paid subscription and can’t even use it. No answer from the support, nothing but chatbots.
What a bad support and what a bad customer service.
Hi, I’m experiencing the same issue. Since GPT-5 was released, both Firefox and Chrome freeze whenever I receive a response - especially when code is generated. I have to close the tab and open a new one each time, which makes the experience very frustrating. Honestly, I haven’t been satisfied with the service since GPT-5 was introduced
same for me too. its getting forzen for every single question. horrible !!!
