We introduce Mistral 7B v0.1, a 7-billion-parameter language model engineered for superior performance and efficiency. Mistral 7B outperforms Llama 2 13B across all evaluated benchmarks, and Llama 1 34B in reasoning, mathematics, and code generation. Our model leverages grouped-query attention (GQA) for faster inference, coupled with sliding window attention (SWA) to effectively handle sequences of arbitrary length with a reduced inference cost. We also provide a model fine-tuned to follow instructions, Mistral 7B -- Instruct, that surpasses the Llama 2 13B -- Chat model both on human and automated benchmarks. Our models are released under the Apache 2.0 license.


The world of artificial intelligence is always advancing, with the goal to create models that are both powerful and efficient. Mistral 7B is a state-of-the-art language model that takes efficiency and performance to new heights. Despite having 7 billion parameters, it outperforms larger models like Llama 2 (13B) and Llama 1 (34B), marking a significant step forward in AI development.
