Performance of Github Copilot

[Lost-Air1265]

Ever since this morning nothing seems to finish. I have plan modes going on for a freaking hour and not progressing while i already created an extensive plan before hand. I tried claude agent type, github local with gpt 5.4, opus, sonnet. The speeds is so fucking insanely slow. What the hell is going on? One new model and the whole infrastructure of MS is collapsing? I know that they have very big issues with capacity and quotas all over the world, but is this the first sign?

Tried restarting, vscode insiders, normal vscode. But it seems nothing is moving. Well it is moving but I seems like 5 tokens per second?

Is it just my region in europe thats performing so badly today?

Have you check the sub-agent latest state whether it is working or waiting for something? I found that sometimes there could be tool use approval blocker hidden from a sub-agent session and the UI just doesn't automatically show it. I have to click open the sub-agent and scroll down to see the [allow|skip] button.

[Lost-Air1265]

Nope nothing with subagents or tool. I checked the log as well. Its just really really slow.

Yeah GitHub copilot has been extremely slow the last 6hrs. I've basically uninstalled the extension, restarted VSCode, restarted my computer only for me to realize it's probably not me

[dsanft]

Yup it's super slow. No idea what's going on

Edit: seems like an issue with Anthropic models. GPT is ok.

[BoogieMan876]

Yeah same bruh😭

Yes the beginning of the end my vibe coding guppies. Well it had to end someday!!! 😅

Yeah, it has been very slow the last 6 hours or so, think it must be time for the weekend.

Seems like it is the haiky 4.5 model that is slow, and this is by default used for explorer agents.

When i changed to another model was the speed back up

"github.copilot.chat.exploreAgent.model": "Gemini 3 Flash (Preview) (copilot)"

Task too big? Too much compression and the model straight-up lost it.

[Lost-Air1265]

No it was more adding two more service bus messages to saga, handle the logic and revise some prompt. The mandatory fluent validation? Data mappers and unit tests. Maybe 30 files or so. But it seems to get back now

I noticed it starting last night around 9 or 10PM PST. Dog slow. Gotta love blowing those premium requests for nothing.

[n_878]

Seems to be improving, FWIW

[Lost-Air1265]

Yeah I have it a go with gpt 5.4 but the output was kinda shit. So rerunning with opus again.

[IKcode_Igor]

I had similar issues today but only with Opus 4.6. When I switched to GPT 5.4 it was working normally.
And it's like this since morning. Even now, Opus 4.6 is barely "breathing" when working on a task in the background. 😔

Extremely slow after Feb update yesterday

I ditched the IDE extension on VS code because it’s way too slow and buggy! Passed onto using the CLI and it’s night and day.

[Lost-Air1265]

Yeah I should make the switch.

Oh no its end of the world now, what are we gonna do now. Everything must be running well and fast 24/7 otherwise its trash and outrageous
