Overview

Gemma 2 is a new open model family by Google. They've released a 9B, 29B param model. A 2B model is also expected.
It performs really well on the Chatbot arena and shows good performance when testing within Khoj as well.
Llama.cpp support for Gemma 2 architecture seems to have stabilized
If Gemma 2 performs well in further testing, it can be made the default offline chat model for Khoj
- Once the 2B param model is released, the model size to download can be automatically chosen based on (V)RAM available
