Github Copilot has become too slow.

Body

Github Copilot has been slowing down steadily for the past month. I'm ready to cancel my subscription. Is this something the community has been seeing as well, or is it just me somehow? Prompts used to be answered immediately, and edits would take just just a couple seconds. I'm at the point now where I ask a query and go get a coffee, and hope it's been answered when I get back. What's the deal? I've tried all the models, all are slow.

I am experiencing the same.

[hendersonh]

And now they remove access to the Gemini 2.5 model; this is the end of the line for me. I will cancel today.

[SenMorgan]

Me too having the same problem

[jackofsometrade]

Ok, today Claude 3.7 Sonnet is performing well enough. The other models are still 5-10 minute wait times.

[Ipsita-Singh]

I am experiencing the same issue as well.

[StuCM]

Yeh it is extremely slow for me and it's frustrating. I used to get instant replies but now I have to wait a few minutes, it really stops your flow. Please fix this

[jink-ucla]

same here. does anyone have the same issue? a single request takes more than 5 minutes for me.

[hajokirchhoff]

Same here. It worked okay until last friday. Suddenly the answers in the chat window take forever. It breaks my concentration and I'd be faster looking things up for myself. Unusable...

I hope it gets fixed soon, I've come to like copilot. I am ready to cancel my subscription, if it's not fixed soon though. Pretty useless at the moment.

[ZeroCool22]

Same, so damn slow....

That's what you get to make it free for everyone!

[jenswachtel]

I am super unhappy too, it is getting too slow!
I paid & subscribed annually, shortly after my renewal you announced it's free in a more limited way...

It really appears you're not treating paying vs free customers differently in terms of speed which is really disappointing.

[satoshiinblack]

My situation is the same; I've recently been thinking about switching over to Cursor.

[gbsr]

Same issue here. It's very very slow the past week. I feel cheated almost as a paying customer. You need to fix this.

[CarboxyDev]

+1. Github Copilot Pro is becoming unbearably slow every passing month. The difference in autocomplete speed between Supermaven Free and Github Copilot Pro is embarrassing.

[vanc]

It's super slow for me this morning. An edit request took over 5 mininutes to complete. Never experienced such slowness.

[Laurence-Cullen]

Also noticing this today...

[hashimwarren]

This developer at Cline did a root analysis and found that Gemini has gotten slower and less stable.

This could perhaps also affect GitHub Copilot

[subhantech]

When using the sonnet 3.7 thinking.. in edit mode or agent (3.7)... then it continuously edits the code. for many iterations.. nothing but junk is added to the code.. and i get warning.. that AI is working for long..do you want to change the prompt.. i had to revert the changes it did..and try again.. this is a bug in Github copilot only..i use other platforms too.. there i did not face this issue.. Thank you, Abdul Samie ******************************************************************************************* " Tomorrow Never Comes Until it's Too Late..."

Has anyone else noticed that since the recent updates, agent mode has become much less reliable? I'm seeing decreased accuracy, more frequent endless loops, and constant response errors.

[lord007tn]

yes, and in gpt 4.1 is refusing the write to file and act like in ask mode not in agent mode

[jackofsometrade]

I've just noticed this too. It's getting confused about what mode it's in, and it claims to have created files and made edits when nothing has been done.

[Kev-La]

Since going to paid subscription it has slowed to a crawl for me. It was so much faster as a free user but i hit a usage limit

[markwpresley]

Was fine for a few days. Now unusable.

[MrOpulence]

The thing is super slow. Truly embarassing. I only started using it with a pro+ subscription 1 or 2 weeks ago and getting rid of it. It's not minutes, but about 30 seconds to get an answer back is not unusual. You can't have a "conversation" like this, you go insane trying to accomplish something. Other ones I use are literally instant regardless of model. Hit enter poof instant answer. This thing....... take a nap, come back for answer. Absurd. Who can actually use this and be productive and not pull their hair out? Support is nonexistent, very - extremely slow, junk.

[hajokirchhoff]

BTW, for those of you trying to use Copilot from Visual Studio:
Try disabling your virus scanner to see if things are faster then. I am not kidding: I had a working copy, where a unittest with only a few, simple SQLite operations that usually ran for 3-4 seconds would take minutes (!) to finish. And when I disabled the virus scanner, not only would the SQLite unittest be back to normal, the copilot response times bounced back to 5-10 seconds. 😮

I've since moved my working copy to a devdrive and copilot has become usable again. (Not good - but usable and occasionally helpful ==> another topic).

So, seriously, it seems that Microsoft Defender can screw up big time and in my case seems to have been the culprit. Might be worth a try.

[sasukevita]

do you know which folder to exclude in windows defender?

[JoyEnergiser]

Also experiencing a massive slowdown, it just started today.

edit* I read the comment above me, switched off defender realtime and boom it started working. Am also writing unit tests

[Kev-La]

I use the github copilot chat within vs code and i'm not sure if this linked to the cause or coincidence but when i wipe my github copilot chat the speed returns to normal.

[toddmcintosh]

This fixed it for me. I started a new chat, and speed returned.

[Squixx]

its related to summarizng the chat, which is really slow

[tvle]

/clear helped me. thanks!

[kitizz]

/clear helped me too
EDIT: Never mind, it didn't :(

[TheUsual251]

I have a GitHub Copilot subscription and agent mode works just fine in VS Code, but very slowly in Visual Studio. Maybe it is because I'm working with a JavaScript project in VS Code and a C# project in Visual Studio.

[LukasdeSouza]

Same here, too slow in agent mode

[EBoiSha]

Same here, it produced so much nonsense the last few times it is scaring. It is like a real human being... not sure if this is good or bad though

[PestoPasto]

Agent mode is still way to slow to be usable. I ask it to do some super simple repetitive tasks like moveing some code from front-end to the back-end and it struggles for 5-10 minutes only to produce absolute unusable garbage so i have to ask it to redo it 2-3 times before it produces anything of value.
I'm actually moving away from using Agent mode because it's faster and less of a headache to do it myself in 9/10 cases.

[rib]

Using GPT5 in Agent mode seems to be excruciatingly slow. It's spending many minutes on trivial steps like "Searched for foo, 1 result" or "Read file, lines X to Y". While I find that using Claude is much more responsive, I also find that it's like an intern with ADHD that keeps on quickly doing the wrong thing and then gets stuck in an infinite loop of repeating the same mistakes. At least GPT5 tends to eventually converge on better solutions (for my use cases) but wow it is soooo slow. In the last 30 minutes or so GPT5 has managed to edit about 40 lines of code in a completely standalone file. In this case it also doesn't make any sense that it keeps on reading the file and searching the file, since it's only dealing with one file which it has fully loaded as context.

[CalfCrusher]

I can agree totally. Honestly is so slow that make no sense at this point. Also it lags to summarize conversations

[veewis]

It's getting slower and slower. For even a tiny task, it keeps changing things over and over — sometimes adding a bunch of useless code, then deleting it again. Each time it only writes two or three lines, but it takes a lot of time overall, and it might still not be fixed. It’s getting slower and harder to use.
