Why Does ChatGPT Keep Freezing?

ChatGPT keeps freezing mainly due to high CPU and RAM usage, browser compatibility issues, network connectivity problems, and software bugs. These factors strain system resources and disrupt ChatGPT’s smooth operation.

High CPU and RAM Usage

ChatGPT’s web interface can demand significant system resources. Users report the ChatGPT tab consuming 20% to 100% of CPU capacity. In some cases, it maxes out CPU usage, causing slowdowns and freezing. RAM usage can spike too, sometimes reaching extreme levels such as 120GB on systems with only 32GB installed. This overload leads to system performance degradation and freezes during interaction.

Browser Impact

Browser choice heavily influences ChatGPT’s stability. Chrome and Edge users often experience high CPU use from the ChatGPT tab. Extensions, especially privacy-focused ones like Privacy Badge, sometimes interfere with script execution or data handling, disrupting ChatGPT responses and causing freezes. Incompatible or outdated browsers exacerbate these issues.

Common Causes of Freezing

  • Insufficient system resources (CPU, RAM, storage capacity)
  • Server overload or downtime
  • Incompatible or outdated browser versions
  • Poor internet connectivity or high network latency
  • Too many simultaneously open chats causing resource hogging (noted especially on Mac)
  • Language locale conflicts, notably with Alpha locale settings

Symptoms of ChatGPT Freezing

  • ChatGPT freezes mid-response generation
  • Brief freezes after almost every query
  • App or browser crashes or device freezes (common on MacBooks)
  • Input fields blocked due to webpage CSS issues (pointer-events problem)

How to Fix ChatGPT Freezing

Manage System Resources

  • Close unnecessary browser tabs and background programs.
  • Archive or remove old ChatGPT conversations, especially on Mac. Excessive chats can slow the app.
  • Wait a couple of minutes after refreshing to allow changes to take effect.

Why Does ChatGPT Keep Freezing and How to Fix It?

ChatGPT keeps freezing because it hogs your computer’s CPU and RAM resources, especially when running in certain browsers like Chrome or Edge. This intense resource use often leads to slow performance, input blocks, and even app crashes. Let’s dig deeper into why this happens and what practical steps you can take to stop the freeze-fest.

Imagine trying to juggle while riding a unicycle on a tightrope—your brain screams for bandwidth and your poor device screams for relief. ChatGPT, powerful as it is, occasionally pushes your system to that edge.

The Culprit: High CPU and RAM Usage

ChatGPT’s website tab can easily max out your CPU usage. Users report the GPT tab in Chrome or Edge jumping between 20% to a jaw-dropping 100% CPU consumption. When you peek at your task manager or activity monitor, the ChatGPT tab looks like it’s throwing a wild CPU party — sometimes taking up 50-60% CPU by itself.

RAM doesn’t escape unscathed either. The app can gulp RAM down, even hitting 120GB usage on machines with only 32GB installed. That’s like trying to pour a river into a teacup. This extravagant memory demand can slow everything else on your computer down, causing freezing and stuttering. Users on Macs often notice lag or freeze upon scrolling archived chats—too many conversations drain memory and choke performance.

Browser and Network Interactions Matter

The browser you use can turn ChatGPT into either a slick ninja assistant or a laggy potato. Chrome, Edge, and Firefox tend to be the recommended choices for their support and optimization. But even these can go rogue if not updated.

If you run ChatGPT with outdated browsers or unblockable interfering extensions like Privacy Badge, you risk freezing. Some extensions meddle in ChatGPT’s delicate dance, causing unexpected halts.

  • Try private browsing modes or switching browsers to see if the issue persists.
  • Clearing ChatGPT’s cache and cookies often helps close resource leaks.
  • Unblocking certain domains, such as chatgpt-async-webps-prod-eastus-8.webpubsub.azure.com, has relieved live response issues faced by some users.

Network woes also contribute. Poor internet connections, high latency, and temporary server overload at OpenAI’s end can all freeze ChatGPT mid-thought. Restarting your router or checking status pages for outages might save your session.

History Says It’s Not New

Is this ChatGPT freezing thing a new kid on the block? Nope. It’s a seasoned bug that’s popped up repeatedly over time. Community forums had grumbled about it months ago. The key difference now is we have more ways to identify and tackle it.

  3. Update or Switch Browsers: Keeping your browser and ChatGPT app updated avoids compatibility issues.
  4. Clear Cache and Cookies: Removing temporary data can erase performance snafus.
  5. Disable Suspicious Extensions: Some add-ons clash with ChatGPT. Disable them and see if things improve.
  6. Adjust the Language Locale: If you’re using experimental Alpha locales, switch back to English and reload the page.

A Nifty Technical Fix: The CSS Pointer-Events Trick

Sometimes, ChatGPT freezes because a webpage element blocks input. You can tweak this yourself:

  • Open the page, press Ctrl+Shift+I (or Cmd+Opt+I on Macs) to open Developer Tools.
  • Switch to the Elements or Inspector tab.
  • Search for the div with an id like enforcement-containerchatgpt-paid.
  • Locate the style pointer-events: auto;.
  • Double click and change auto to none.
  • Press Enter, then test if input works outside Developer Tools.
  • Close Developer Tools and refresh the page.

This bypasses the element blocking your typing and can solve those frustrating frozen inputs.

When to Call for Reinforcements

If all else fails, contacting OpenAI support is the next step. However, many users report difficulty finding a straightforward way to submit requests, even as paid subscribers. It’s like calling customer service and getting put on hold forever.

Patience helps here—OpenAI is likely aware and working on fixes once users highlight these performance pains. Meanwhile, using the above hacks keeps your workflow flowing with fewer freeze moments.
