It's the best model, very stable, of all of the ones I tried, it's personable and doesn't moralize, and works great with RAG. I have not successfully fine-tuned it since I am focusing on RAG, although it has a 2k context but you can up the alpha to 2.5 and get 4k with no perceptible quality loss. There is an 8k super hot version but this one is more stable.
