+# 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](https://huggingface.co/Yhyu13/LMCocktail-10.7B-v1.git) model. You can also check the leaderboard at [./Alpaca_eval/chatgpt_fn_--LMCocktail-Mistral-7B-v1/](./Alpaca_eval/chatgpt_fn_--LMCocktail-Mistral-7B-v1/)
