+    """Llama 3: Cutting-Edge Foundation and Fine-Tuned Chat Models
+    
+        The Llama 3 release introduces a new family of pretrained and fine-tuned LLMs, ranging in scale
+        from 8B and 70B parameters. Llama 3 models are designed with enhanced
+        efficiency, performance, and safety, making them more capable than previous versions. These models
+        are trained on a more diverse and expansive dataset, offering improved contextual understanding 
+        and generation quality.
+    
+        The fine-tuned models, known as Llama 3-instruct, are optimized for dialogue applications using an advanced
+        version of Reinforcement Learning from Human Feedback (RLHF). Llama 3-instruct models demonstrate superior
+        performance across multiple benchmarks, outperforming Llama 2 and even matching or exceeding the capabilities 
+        of some closed-source models.
+    
+        Pretrained models can be loaded with :meth:`.pretrained` of the companion
+        object:
+    
+        >>> llama3 = LLAMA3Transformer.pretrained() \\
+        ...     .setInputCols(["document"]) \\
+        ...     .setOutputCol("generation")
+    
+    
+        The default model is ``"llama3-7b"``, if no name is provided. For available
+        pretrained models please see the `Models Hub
+        <https://sparknlp.org/models?q=llama3>`__.

+            Maximum length of output text, by default 60

+            Whether or not to use sampling; use greedy decoding otherwise, by default False

+            top-k-filtering, by default 40
+        topP
+            Top cumulative probability for vocabulary tokens, by default 1.0
+    
+            If set to float < 1, only the most probable tokens with probabilities
+            that add up to ``topP`` or higher are kept for generation.
+        repetitionPenalty
+            The parameter for repetition penalty, 1.0 means no penalty. , by default
+            1.0
+        noRepeatNgramSize

+        ignoreTokenIds
+            A list of token ids which are ignored in the decoder's output, by
+            default []
+    
+        Notes
+        -----
+        This is a very computationally expensive module, especially on larger
+        sequences. The use of an accelerator such as GPU is recommended.

+        **Paper Abstract:**
+    
+        *Llama 3 is the latest iteration of large language models from Meta, offering a range of models
+        from 1 billion to 70 billion parameters. The fine-tuned versions, known as Llama 3-Chat, are 
+        specifically designed for dialogue applications and have been optimized using advanced techniques 
+        such as RLHF. Llama 3 models show remarkable improvements in both safety and performance, making 
+        them a leading choice in both open-source and commercial settings. Our comprehensive approach to 
+        training and fine-tuning these models is aimed at encouraging responsible AI development and fostering 
+        community collaboration.*
