+    """Mistral 7B
+
+    Mistral 7B, a 7.3 billion-parameter model that stands out for its efficient and effective
+    performance in natural language processing. Surpassing Llama 2 13B across all benchmarks and
+    excelling over Llama 1 34B in various aspects, Mistral 7B strikes a balance between English
+    language tasks and code comprehension, rivaling the capabilities of CodeLlama 7B in the
+    latter.
+
+    Mistral 7B introduces Grouped-query attention (GQA) for quicker inference, enhancing
+    processing speed without compromising accuracy. This streamlined approach ensures a smoother
+    user experience, making Mistral 7B a practical choice for real-world applications.
+
+    Additionally, Mistral 7B adopts Sliding Window Attention (SWA) to efficiently handle longer
+    sequences at a reduced computational cost. This feature enhances the model's ability to
+    process extensive textual input, expanding its utility in handling more complex tasks.
+
+    In summary, Mistral 7B represents a notable advancement in language models, offering a
+    reliable and versatile solution for various natural language processing challenges.
+
+    Pretrained models can be loaded with :meth:`.pretrained` of the companion
+    object:
+
+    >>> mistral = MistralTransformer.pretrained() \\
+    ...     .setInputCols(["document"]) \\
+    ...     .setOutputCol("generation")
+
+
+    The default model is ``"mistral-7b"``, if no name is provided. For available
+    pretrained models please see the `Models Hub
+    <https://sparknlp.org/models?q=mistral>`__.

+
+    Notes
+    -----
+    This is a very computationally expensive module especially on larger
+    sequence. The use of an accelerator such as GPU is recommended.

+
+    **Paper Abstract:**
+
+    *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.*
