Same issue, tried with arc and chrome, m1 mac, 8gb ram not maxed out
+1 it started a couple of weeks ago, affecting primarily my Chrome on Android
Started yesterday for me and it’s been like this for two days now. Doesn’t seem to be fixed. Windows 10, Chrome or Firefox, as soon as the conversation grows a bit, or you request a longer output with a bit of a complex code assignment, it grows like crazy, lags, then crashes the tab.
I’ll also chime in, it seems to get worse the longer the conversation goes. Eventually the tab freezes and its impossible to even close the tab.
Poorly made website. No excuse for such usage from the UI. It’s litteraly just text and syntax highlighting. Hire me

archived all my chat, but the crash persists.

Out of memory : many objects from highlight.js 
Finally got to test it with Chrome on my computer, and it’s at around 9 edits (10 pages) before I need to start fresh. The tab reaches 4GB before it starts getting unresponsive for me (I’m working with 16GB). I can only manage 2 edits on mobile by comparison.
It’s been over 24 hours and there doesn’t seem to be anything on the OpenAI status page, so I don’t think a fix is coming any time soon.
Oh dear, I’m not the only one experiencing that issue! That is why I keep using 3.5 over the 4.0

There looks to be a memory leak in client side code .
Start in an small existing chat.
Chrome 1 gb memory
ask a question in the chat.
and it slowly begins to output the response.
memory use in climbs to 5gb which just this tab !!!
after 30 secs 10% CPU and 4gb more in chrome…
and eventually it crashes chrome with an out of memory error (aw snap)
Use chatgpt to fix the client side js

Same, on Safari, Chrome, Microsoft - Mac Mini, Laptop, Windows 11 Pro on another Desktop Windows machine - It is, if nothing else, not prejudicial to one browser over the other or OS. Anxious to see if there’s a resolution that I am just missing here or elsewhere. Thanks for the sanity check though…it’s not just me.

Using 3.5 actually does not budge the needle on the RAm or CPU at all. good catch, however 3.5 has no realtime access, can this be related?
Asked GPT about it, first one is pretty obvious though:
chrome_settings:
steps:
- description: Disable Memory Saver Mode
action:
- open_chrome: “chrome://flags/#high-efficiency-mode-available”
- set_flag:
flag_name: “Enable the high-efficiency mode feature in the settings”
value: “Disabled”
- description: Increase Tab Cache Memory
action:
- open_chrome: “chrome://flags/#enable-tab-discarding”
- set_flag:
flag_name: “Proactive Tab Freeze and Discard”
value: “Disabled”
- description: Disable Tab Freezing and Discarding
action:
- open_chrome: “chrome://discards/”
- set_pinning_or_command_line_flags: “Pin tabs or use the command line flags”
- description: Run Chrome with Command Line Flags
action:
- create_shortcut:
location: “Desktop”
application: “Chrome”
- right_click_shortcut:
description: “Right-click on the shortcut and select Properties”
- edit_target_field:
description: “In the Target field, add the following flags after the existing text”
flags: “–process-per-tab --disable-background-timer-throttling --disable-backgrounding-occluded-windows --max_old_space_size=4096”
flags_explanation:
–process-per-tab: “Forces Chrome to use a separate process for each tab.”
–disable-background-timer-throttling: “Disables throttling of JavaScript timers in background tabs.”
–disable-backgrounding-occluded-windows: “Prevents Chrome from treating occluded windows as background windows.”
–max_old_space_size: “Increases the maximum memory size for the V8 JavaScript engine’s old memory space to 4096MB.”
Solution: I switched to chatgpt desktop app. No more crashes

Here too, 32 gb RAM, Chrome Says “out of Memory” when 2 o 3 generations are done.
Easy fix - after each answer is completed, refresh the tab - quick command / ctrl R and it seems to clear down. This was happening after about every 2 or 3 prompts before I started doing that. Hopefully one day, they will let me use the desktop app.

Also experiencing this (except on 3.5) and it seems to be accompanied by severe hallucinations. I’m a software dev and it seems to be hallucinating far more than usual and becomes repetitive in its wrongness much faster, to where I’m forced to open a new chat tab far more often than has been the case in the recent past.
