You do have a valid point that the LLM is closed aka OpenAI's API. We were thorn about it ourselves but decided to release with OpenAI because of it's ease of use for devs. We have already tested Llama-2 and seeing more and more pull for it, especially by enterprise who have can't use OpenAI because of privacy and IP issues. Thus, OSS LLMs are next on our roadmap :)

Rest of the stack is fully open-source and it's much more than a wrapper. Maybe the impression comes from the aspect that we've made getting started dead simple with the minimal Copilot example. The framework covers a lot of ground so you can build your copilot easily: backend, adding a knowledge base & dynamic data, front-end, monitoring & evaluation.

This is pretty much v0.1 release. What else would you love to see?

True, GitHub copilot is also using gpt3.5 at the moment so it's actually kind of the same

You understand it fully
