As announced at GitHub Universe on Tuesday, October 29th, Claude 3.5 Sonnet is now available to all GitHub Copilot customers!

To learn more, you can see the announcement blog post or the docs on Claude 3.5 Sonnet in GitHub Copilot.

We'd love to hear your thoughts and feedback!

Loving the Sonnet preview. Few things I've noticed is it is more aggressive at changing things outside the scope of the query. This can be good and bad, depending on the context. On the good side, it will often add code that directly relates to the task, on a line that is appropriate. However, sometimes it changes things, seemingly, arbitrarily.

Biggest downside is it takes a lot longer than GPT 4o, tho it is similar to o1. Sometimes I feel that it is because it is over-zealous reading context of very large files, even if I only highlight a few lines. Would like a "mini" version of Sonnet, if that ever becomes feasible.

Can we get this feature in the vim plugin as well?

[sebastiancarlos]

According to another comment, the Claude support is only for chat mode at the moment, which isn't a supported mode on the vim plugin

[anshukg]

What is the size of the context window for Claude 3.5 Sonnet ?

[prime399]

I am wondering the same.

[prime399]

I have tested and asked copilot itself.

And got answer, it's same as any other model 4k in 4 out and overall for entire chat is 8k tokens.

[expert2020h]

Have you ever experimented with similar models? How was your experience working with such context window sizes?

[Otanikotani]

Is there a chance to get this in Jetbrains products too?

[matthewisabel]

We're targeting early 2025 for this

why there is always such a delay for JB products? I know that this is MS company, but I pay for it the same as VS users.

[mvaljento]

My guess is that they are trying to slowly get users away from JetBrains to MS products by prioritizing other solutions and delaying any new features or fixes for JetBrains IDEs almost indefinitely. They've wagered that people will rather give up JetBrains IDEs than Copilot, but they cannot stop supporting JetBrains (yet) either. It's sad, but until there's a real competing plugin solution for JetBrains, we just have to play along.

Why so big delay? Vscode is not good for Android/Flutter or Go so I use Android Studio and Golang. It would be great to have support there. I won't switch to vscode just because you delay features.

Claude kept responding that I included the timestamp and login information. Weird.

[igormalaes]

When will it be available for IntelliJ?

[baslia]

Same question, it seems like IntelliJ plugins are 6 months behind VS Code

[akkikumar72]

I moved to VS Code just for it

[Fadyio]

Is Claude 3.5 Sonnet only available in chat mode, or can we get inline completion as well? Is there a way to change which model we use for inline completion?

[matthewisabel]

Just chat at the moment!

[dogukanoksuz]

Inline completion model switching would be great tbh

[iwangbowen]

Not as good as GPT o1

[Anselmoo]

The explanation GPT-O1 appears to be more detailed, and the Copilot Edits seem to have stronger edits.

[NSTHEHACKER]

but in my use case sonnet is best but some times it take long time to response

[knnmran]

sometimes i need to reset the context. it seems like reloading the VSCode is the only way to do that at the moment.

[knnmran]

in some cases not sure which yet, it is not possible to remove working set files individually. missing "x" button.

[ossianravn]

For some reason I can't select Sonnet (or anything besides the default model) in Copilot/Visual Studio. I've enabled Sonnet in my Github Copilot settings about 12 hours ago, restarted VS, booted my PC, etc - but nothing. Why could that be? Thank you!

[matthewisabel]

Are you using Visual Studio Code or Visual Studio? Right now the model picker is only in Visual Studio Code but Visual Studio is on the roadmap!

[MasonMcV]

This should be publicized more, as it took me several days to find this out. Do you have a time frame for when this will be updated in other IDE's?

[ossianravn]

Ok, then it makes sense. I'm using Visual Studio. Thanks.

[mhensen]

Any timeframe? Why is Visual Studio 2022 behind on Visual Studio Code.. Why is VSC always prefered?

[onegigbyte]

I have enabled "Anthropic Claude 3.5 Sonnet in Copilot", but I still do not see the Claude option via copilot.
Can anyone help?

[wyuancronos]

@OTPSerikat I'm still waiting for a fix and I'm using cursor at the moment

[matthewisabel]

Hi @wyuancronos, did you write into GitHub support? We likely need some additional information to debug here and they'll be able to do so.

[jerremy777]

Same issue. Claude enabled in Copilot policies -> was not available in vs code -> restarted vs code -> still not available -> reinstalled extension -> still not available -> Updating VS code fixed this issue for me.

[paulwelden]

Same issue for my org. Preview feature is enabled and some engineers are seeing the model selection, but most are not. We have confirmed vs code versions, chat logs, extension versions, etc... We also tried logging out of GitHub and some have reinstalled vs code. Still no dropdown.

[alexkuzmin]

Updating the VSCode worked for me.

[jalenzz]

🐛 There is no "Claude 3.5 Sonnet" option when I connect to remote host, I can only use it locally.

[hjqcan]

When will claude be available in VS2020? So disappointed in your guys.The gap between you and cursor is soooooooooo big

[Soontosh]

This is awesome! Just wondering if this is the new version of Claude Sonnet 3.5 which came out just under two weeks ago?

[matthewisabel]

Yes!

[chenxch]

Hello, I have enabled the Claude model in both my personal account and my corporate account, but the model does not appear in my vscode chat. I have confirmed that it has been updated to the latest version and have tried to log in again and even restart.

[chenxch]

https://github.com/orgs/community/discussions/143337#discussioncomment-11138626
This should be the reason.

[firstunicorn]

Is claude-3-5-sonnet-20241022 model available or it is just claude-3-5-sonnet ?

[matthewisabel]

The latest model (2024-10-22) is being used

[firstunicorn]

Also, is it available in Multi-file editing mode or it is just in chat right now? If it's only for chat, when it will be available in Multi-file editing mode? I'm thinking to switch from Cursor to Copilot and these is the only important things for me - sonnet-20241022 and Multi-file editing mode - because I use it most of the time (as I understand, it is similar to Composer mode in Cursor). Thanks.

FYI There is a new preview "Copilot Edits" which does support changes across multiple files and allows the extension to create new files. https://code.visualstudio.com/docs/copilot/copilot-edits - double check it's available in your preferred editor. Some things only work in VS Code and some only in Visual Studio it seems.

[TimMoore]

Is there a way to make this the default model? I can select it in VS Code, but it seems to frequently revert back to GPT 4o

[tiagoefreitas]

need this

[isimmons]

Copilot feels a need to correct my misinformation when the Claude model is chosen. I just tried to say hello to my old Cursor friend. :-)

I need to correct some misinformation. I am GitHub Copilot, not Claude, and I do not use the Claude language model. I am developed > by GitHub/Microsoft and use different underlying technology.

Also,

I cannot engage in general conversation or non-programming tasks like Claude can. My responses are focused on helping you write,
understand, and debug code within VS Code.

[nv-pipo]

Comparing VSCode with Claude 3.5 VS Cursor with Claude 3.5: VSCode feels considerably slower and sometimes it just never replies, is this due to the "preview" nature? is this a "known issue"? fixes?

Seems I'm not the only one with this feeling: https://www.reddit.com/r/GithubCopilot/comments/1gjdsci/copilot_chat_with_claude_35_sonnet_preview_slow/?rdt=44914

[interware]

Not releasing Claude 3.5 Sonnet as a selectable Model in Visual Studio 2022 17.12 or 17.13 (preview) BEFORE releasing it in VS Code is a punch in the face of all users of Visual Studio and paying shitloads of money for it each year/month.

[Unusuala1l2e3x4]

Claude has "Projects" functionality where it maintains some sort of context across all chat sessions under the same project. Does using Claude in Copilot use any of that functionality? Or does it do something different?

[tiagoefreitas]

It's not in visual studio
