LM-cocktail Mistral 7B v1

This is a 50%-50% model of two best Mistral models

https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2

https://huggingface.co/xDAN-AI/xDAN-L1-Chat-RL-v1

both claimed to be better than chatgpt-3.5-turbo in almost all metrics.

Alpaca Eval

I am thrilled to announce that ChatGPT has ranked LMCocktail 7B as the second best model next to GPT4 on AlpcaEval in my local community run, even greater than my previously best LMCocktail-10.7B-v1 model. You can also check the leaderboard at ./Alpaca_eval/chatgpt_fn_--LMCocktail-Mistral-7B-v1/
