A lot of teams we talk to switched from an in-house solution to either directly using Danswer or building on top of Danswer. Glad you liked the demo!

We're using E5 base by default but there's an embedding model admin page to choose alternatives. There's also an API for it if you know what you're doing, you can even set one of the billion+ parameter LLM bi-encoders if you want (but you'd need a GPU for sure).
