+    """StarCoder2: The Versatile Code Companion.
+
+    StarCoder2 is a Transformer model designed specifically for code generation and understanding.
+    With 13 billion parameters, it builds upon the advancements of its predecessors and is trained
+    on a diverse dataset that includes multiple programming languages. This extensive training
+    allows StarCoder2 to support a wide array of coding tasks, from code completion to generation.
+
+    StarCoder2 was developed to assist developers in writing and understanding code more efficiently,
+    making it a valuable tool for various software development and data science tasks.
+
+    Pretrained models can be loaded with :meth:`.pretrained` of the companion
+    object:
+
+    >>> starcoder2 = StarCoder2Transformer.pretrained() \\
+    ...     .setInputCols(["document"]) \\
+    ...     .setOutputCol("generation")
+
+    The default model is ``"starcoder2-13b"``, if no name is provided. For available
+    pretrained models please see the `Models Hub
+    <https://sparknlp.org/models?q=starcoder2>`__.

+    Parameters
+    ----------
+    configProtoBytes
+        ConfigProto from tensorflow, serialized into byte array.
+    minOutputLength
+        Minimum length of the sequence to be generated, by default 0
+    maxOutputLength
+        Maximum length of output text, by default 20
+    doSample
+        Whether or not to use sampling; use greedy decoding otherwise, by default False
+    temperature
+        The value used to modulate the next token probabilities, by default 1.0
+    topK
+        The number of highest probability vocabulary tokens to keep for
+        top-k-filtering, by default 50
+    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
+        If set to int > 0, all ngrams of that size can only occur once, by
+        default 0

+        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
+    sequence. The use of an accelerator such as GPU is recommended.

+
+    **Paper Abstract:**
+
+    *The BigCode project, an open-scientific collaboration focused on the responsible
+    development of Large Language Models for Code (Code LLMs), introduces StarCoder2. In
+    partnership with Software Heritage (SWH), we build The Stack v2 on top of the digital commons
+    of their source code archive. Alongside the SWH repositories spanning 619 programming
+    languages, we carefully select other high-quality data sources, such as GitHub pull requests,
+    Kaggle notebooks, and code documentation. This results in a training set that is 4× larger
+    than the first StarCoder dataset. We train StarCoder2 models with 3B, 7B, and 15B parameters
+    on 3.3 to 4.3 trillion tokens and thoroughly evaluate them on a comprehensive set of Code LLM
+    benchmarks.*
+
+    *We find that our small model, StarCoder2-3B, outperforms other Code LLMs of similar size on
+    most benchmarks, and also outperforms StarCoderBase-15B. Our large model, StarCoder2-15B,
+    significantly outperforms other models of comparable size. In addition, it matches or
+    outperforms CodeLlama-34B, a model more than twice its size. Although DeepSeekCoder-33B is
+    the best-performing model at code completion for high-resource languages, we find that
+    StarCoder2-15B outperforms it on math and code reasoning benchmarks, as well as several
+    low-resource languages. We make the model weights available under an OpenRAIL license and
+    ensure full transparency regarding the training data by releasing the Software Heritage
+    persistent Identifiers (SWHIDs) of the source code data.*
