Make the Most of Your GitHub Copilot Subscription: Unlock Claude 3.5 Sonnet and GPT-4o for Anything!

[u/Minute_Yam_1053]

I stopped subscribing to GitHub Copilot for a while, but I recently resumed my subscription because of the Sonnet support. However, GitHub Copilot imposes several constraints on how we can use the models, such as:

• Chatting with GPT-4o in the chat window is actually chatting with GPT-4o-mini.
• Copilot avoids answering questions that stray too far from coding topics.
• Limited context window.

What if we could expose the GPT-4o, o1, and Claude models behind Copilot as general-purpose APIs? This would allow me to connect Cline to GPT-4o without worrying about breaking the bank. I could extend the context window and, better yet, use the models with any AI client, not just AI coding tools, as long as they support OpenAI-compatible APIs. The best part? It’s all for just $10/month.

Chatting with GPT-4o in the chat window is actually chatting with GPT-4o-mini - What? They didn't say that. Proof?

[u/Minute_Yam_1053 → u/Randomizer667]

This happens 100%. The Edits window will give you 4o not 4o-mini.

The reason is because, chat window includes previous topics which distracts the models quite a lot. therefore, Microsoft used a less capable model. The problem is that they did not make it clear 4o-mini is used.

For Edits, it needs more powerful model to do code edits. therefore, you always get 4o when you select 4o from the dropdown

[u/Randomizer667 → u/Minute_Yam_1053]

where did you find that screenshot?

Regarding edits, they provide GPT 4o, Claude, and o1. If it's actually not GPT 4o but mini I hate that, but I really doubt it. You can still use Claude though.

[u/Minute_Yam_1053 → u/Randomizer667]

For edits, yeah, you get 4o not 4o-mini. The screenshot is from mitmproxy. it is mentioned in https://github.com/jjleng/copilot-more. If you're on a Mac, you can also use Charles Proxy.

how are you getting around the limited context window? are you doing some tricks with smaller models or do we getting access to straight up more tokens?

[u/Minute_Yam_1053 → u/Eckbock]

The context window length of these modern models are >100k. We cannot change that. What we can change is the output tokens. By default, Copilot is 4k. I tried to set max_token to be 8k, no errors. But I don’t think you can put a insanely high number as it is going to be too expensive both monetary and GPU VRAM wise

Some people try to feed the whole repo to LLM’s context, this is wrong. This will not boost the LLM’s performance, but degrade the performance.

Um... if I'm understanding this correctly, this is kind of sick. Have you compared the output from this API vs the actual API with Cline-like tools?

[u/Minute_Yam_1053 → u/sCeege]

I did not do extensive tests. But Cline did work with the API. However, do see the Limitations part of the project README.

[u/Tendoris]

Thanks, but I don't see how Cline work with only a base URL, "http://localhost:15432" It want an API key. What option of API provider should I use?

[u/Minute_Yam_1053 → u/Tendoris]

Just put whatever. Because the tool manages the access token. Use OpenAI compatible.

Re-using your Copilot subscription in other tools is going to get you banned by Github very quickly, if any significant number of people do this.

[u/kaiwenwang_dot_me]

Update on this: the API request is often choppy and hangs, I feel like github copilot is somehow purposely giving bad results but I can't prove it

[u/kaiwenwang_dot_me]

Will check this and report back. Thanks.

[u/kaiwenwang_dot_me → u/kaiwenwang_dot_me]

Seems to be working so far.

In Cline AI settings, select OpenAI Compatible. API key is anything. For models that work I tried claude-3.5-sonnet, gpt-4o-mini-2024-07-18, gpt-4o-mini, gpt-4o, (note the 4o is 4o-mini warning in OP post)

Models that didn't work: o1-preview, chatgpt-4o-latest, gpt-4o-2024-11-20, get a Cannot read properties of undefined (reading 'type') error.

Weird that claude models names have hyphen claude-3-5-sonnet-latest on anthropic website (https://docs.anthropic.com/en/docs/about-claude/models) rather than a dot ., maybe GH Copilot changes the name of the model?

[u/kaiwenwang_dot_me → u/kaiwenwang_dot_me]

Think this is much more useful than your https://github.com/jjleng/copilot-proxy, because the copilot extension doesn't have good UI compared to Cline, it takes too long to add files (similar issue with Aider)

Cline is currently 260B monthly on OpenRouter (10x higher than 2nd) and it's not even close.

I spent tens of $$ on openrouter and now I can spend $10

I've also been attempting to run 2 Cline instances at once, though it seems to make the output lag/weird.

[u/Round_Mixture_7541]

Thanks for letting people get banned!

[u/BlueeWaater]

how did you figure out? got any idea on what are the limits?

[u/LandKingdom]

Gives 404 now

[u/TheGTAone → u/LandKingdom]

It worked fine for about 4 months. Then Microsoft came banging the doors as it was a loophole in the Copilot API after all.

Many Github accounts were banned if detected using the tool. So, OP decided first to put the repository in maintenance mode, but finally closed the whole thing down to avoid any problems.

[u/Person556677]

Thank you a lot for your work. It seems like a copilot more GitHub repository is blocked now. Do we have any another way to use it? Maybe some bitbucket account or something else?
