Mistral 7B
Mistral AI team is proud to release Mistral 7B, the most powerful language model for its size to date.
Mistral 7B in short
Mistral 7B is a 7.3B parameter model that:
Outperforms Llama 2 13B on all benchmarks
Outperforms Llama 1 34B on many benchmarks
Approaches CodeLlama 7B performance on code, while remaining good at English tasks
Uses Grouped-query attention (GQA) for faster inference
Uses Sliding Window Attention (SWA) to handle longer sequences at smaller cost
We're releasing Mistral 7B under the Apache 2.0 license, it can be used without restrictions.
Download it and use it anywhere (including locally) with our reference implementation,
Deploy it on any cloud (AWS/GCP/Azure), using vLLM inference server and skypilot,
Use it on HuggingFace.
Mistral 7B is easy to fine-tune on any task. As a demonstration, we're providing a model fine-tuned for chat, which outperforms Llama 2 13B chat.
Performance in details
We compared Mistral 7B to the Llama 2 family, and re-run all model evaluations ourselves for fair comparison.
Performance of Mistral 7B and different Llama models on a wide range of benchmarks. For all metrics, all models were re-evaluated with our evaluation pipeline for accurate comparison. Mistral 7B significantly outperforms Llama 2 13B on all metrics, and is on par with Llama 34B (since Llama 2 34B was not released, we report results on Llama 34B). It is also vastly superior in code and reasoning benchmarks.The benchmarks are categorized by their themes:
Commonsense Reasoning: 0-shot average of Hellaswag, Winogrande, PIQA, SIQA, OpenbookQA, ARC-Easy, ARC-Challenge, and CommonsenseQA.
World Knowledge: 5-shot average of NaturalQuestions and TriviaQA.
Reading Comprehension: 0-shot average of BoolQ and QuAC.
Math: Average of 8-shot GSM8K with maj@8 and 4-shot MATH with maj@4
Code: Average of 0-shot Humaneval and 3-shot MBPP
Popular aggregated results: 5-shot MMLU, 3-shot BBH, and 3-5-shot AGI Eval (English multiple-choice questions only)
