v3.7.4

Which API Provider are you using?

VS Code LM API

Which Model are you using?

Claude 3.7 Sonnet

What happened?

When submitting a prompt the error below is being returned immediately. This is happening only with both Claude 3.7 Sonnet and Thought models. It was working yesterday.

Request Failed: 400 {"error":{"message":"Model is not supported for this request.","param":"model","code":"model_not_supported","type":"invalid_request_error"}}

Steps to reproduce

1. Choose API Prodiver: VS Code LM API with Copilot installed
2. Select the Claude 3.7 Sonnet model
3. Send any prompt

Relevant API REQUEST output

Additional context

No response

Edit:
I just tested with Cline and it is also giving the same error. I'm wondering if they have blocked third party extensions.

I think they’re having some problems rolling it out on the copilot side. Are you able to send a copilot chat with the model?

Yes the copilot chat works just fine with both of the new claude 3.7 models. It's just not working in Roo.

i have the same issue, what is the solution? copilot chat works fine

[Leongeng2025]

I occured the same issue, awaiting for the solution. My copilot chat works fine.

[YuShiWei923]

same issue on roo, copilot chat can work well

[EndEdEd]

Same here

[feijie999]

me too

[GaryJurgens]

Same Issue, Cline and RooCode, Chat works fine. Was working yesterday morning, then there was the shutdown, but GitHub status says it resolved now.

Same here

[feijie999]

The current system in use is the latest version of VSCode for macOS, it is uncertain whether there is such a problem on the Windows system.

[GaryJurgens]

I see there was a Upgrade that was Pushed a few Minutes ago on this Extension. i upgraded it, restart everything, but still encounter the same problem. - Windows 11

[EndEdEd]

In my case It has been recovered for hours now, and it's working fine inside GitHub Copilot. The problem appears when using it with VSCode LM API.

No it is not working. Both Cline and RooCode. Copiplot is working well.

[truong211]

github try to block it, claude 3.5 sonnet is fine

[truong211]

I just tested with Cline and it is also giving the same error. I'm wondering if they have blocked third party extensions.

they block new claude 3.7 only

[truong211]

I occured the same issue, awaiting for the solution. My copilot chat works fine.

solution is pay the money, buy the real OpenRouter services

[nicucalcea]

@truong211 this is asinine, 3.7 costs the same as 3.5.

[kiransterling]

Same issue with me when trying to use sonnet 3.7 in github copilot getting this error --> Request Failed: 400 {"error":{"message":"Model is not supported for this request.","param":"model","code":"model_not_supported","type":"invalid_request_error"}}

[vatva693]

@truong211 this is asinine, 3.7 costs the same as 3.5.

The new Claude 3.7 Sonnet model has low capacity and is limited, so they are prioritizing GitHub Copilot Chat users first and temporarily disabling third party use of Claude 3.7 until they have more capacity.

[RebaiFedi]

Me too same problem!!

[mrubens]

Unfortunately I’m not aware of anything that we can do about this on the Roo Code end, but if anyone has ideas let me know!

So basically, it doesn't work also for Copilot Chat, however in the system message they have put

{"role":"user","content":"what llm model are you"},{"role":"assistant","content":"I'm GitHub Copilot, and I use the Claude 3.7 Sonnet (Preview) large language model as mentioned in my system instructions."

so if you ask it it will tell you that it is 3.7, however at the end of the body I can see they are using gpt-4o-mini instead

I confronted it and it told me - Based on my capabilities and instructions, I'm using Claude 3.7 Sonnet (Preview). That said, the specific version isn't as important as being able to provide useful assistance with your project."

[alioshr]

...however at the end of the body I can see they are using gpt-4o-mini instead

@enerage How did you infer this?

I was investigating the issue, I captured the request via fiddler and you can see the actual model they use for the request there

Hmm, intresting.

[CoderF3ff]

Maybe this debugging can be helpful
It seems like the root cause is in model names

[charithharshana]

It was working initially in the Roo code, then I saw Claude 3.7 Sonnet removed from the Roo code- VS Code LM API and then came back after few hours, from that time it's not working :(

[jesussmile]

same here not working

[mirzaaghazadeh]

enable 3.7 from setting ! https://github.com/settings/copilot

[shiplove-fast]

this is a working solution. but use at your own risk

[leen12]

same issue here it is enabled in the settings

[GaryJurgens]

same issue here it is enabled in the settings

Same Issue.

[majdaleid]

same issue here. any solution? v.3.7.8

[alioshr]

@majdaleid look up at @shiplove-fast 's comment. I have tested it and it works

[dambros-nstech]

I tried copilot-more recommended by @shiplove-fast but unfortunately couldn't get it to work as well. There is an issue open on the repo with some people having the same 421: API error: Misdirected Request error as I am getting.

[neKamita]

this is a working solution. but use at your own risk https://github.com/jjleng/copilot-more

the main problem is that it gets rate limit super fast

For enterprise accounts, replace the URL address in server.py with the format api.business.githubcopilot.com.

[vatva693]

Unfortunately I’m not aware of anything that we can do about this on the Roo Code end, but if anyone has ideas let me know!

https://github.com/jjleng/copilot-more is still working fine with both claude-3.7-sonnet and claude-3.7-sonnet-thought. Can you investigate this? I think It’s probably due to header masking as same as normal github copilot chat @shiplove-fast.

[talhavatan98]

same issue :(

[laurencebush]

Cannot get it working

could you provide @vatva693 a guide to install this? i get the http://0.0.0.0:15432 server running but on roo cline
i set base url http://localhost:15432
api key (what does it go in here?)
model claude-3.7-sonnet

and i get

Error
Unexpected API Response: The language model did not provide any assistant messages. This may indicate an issue with the API or the model's output.

Roo is having trouble...
This may indicate a failure in his thought process or inability to use a tool properly, which can be mitigated with some user guidance (e.g. "Try breaking down the task into smaller steps").
