At every layer, for every token, a router network chooses two of these groups (the “experts”) to process the token and combine their output additively. This technique increases the number of parameters of a model while controlling cost and latency, as the model only uses a fraction of the total set of parameters per token. Mixtral is pretrained with multilingual data using a context size of 32k tokens. It either matches or exceeds the performance of Llama 2 70B and GPT-3.5, over several benchmarks. In particular, Mixtral vastly outperforms Llama 2 70B on mathematics, code generation, and multilingual benchmarks.'"

On both WMT 2014 English-to-German and WMT 2014 English-to-French translation tasks, we achieve a new state of the art. In the former task our best model outperforms even all previously reported ensembles. \\\\n\\\\n\\\\nWe are excited about the future of attention-based models and plan to apply them to other tasks.

Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 English-to-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.8 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature.

 # Contribute Documentation
 
-The docs directory contains Documentation and API Reference.
+LangChain documentation consists of two components:
 
-Documentation is built using [Quarto](https://quarto.org) and [Docusaurus 2](https://docusaurus.io/).
+1. Main Documentation: Hosted at [python.langchain.com](https://python.langchain.com/),
+this comprehensive resource serves as the primary user-facing documentation.
+It covers a wide array of topics, including tutorials, use cases, integrations,
+and more, offering extensive guidance on building with LangChain.
+The content for this documentation lives in the `/docs` directory of the monorepo.
+2. In-code Documentation: This is documentation of the codebase itself, which is also
+used to generate the externally facing [API Reference](https://api.python.langchain.com/en/latest/langchain_api_reference.html).
+The content for the API reference is autogenerated by scanning the docstrings in the codebase. For this reason we ask that
+developers document their code well.
 
-API Reference are largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code and are hosted by [Read the Docs](https://readthedocs.org/).
-For that reason, we ask that you add good documentation to all classes and methods.
+The main documentation is built using [Quarto](https://quarto.org) and [Docusaurus 2](https://docusaurus.io/).
 
-Similar to linting, we recognize documentation can be annoying. If you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.

-## Build Documentation Locally
+We appreciate all contributions to the documentation, whether it be fixing a typo,
+adding a new tutorial or example and whether it be in the main documentation or the API Reference.
+
+Similar to linting, we recognize documentation can be annoying. If you do not want
+to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
+
+## 📜 Main Documentation
+
+The content for the main documentation is located in the `/docs` directory of the monorepo.
+
+The documentation is written using a combination of ipython notebooks (`.ipynb` files)
+and markdown (`.mdx` files). The notebooks are converted to markdown
+using [Quarto](https://quarto.org) and then built using [Docusaurus 2](https://docusaurus.io/).
+
+Feel free to make contributions to the main documentation! 🥰
+
+After modifying the documentation:
+

+## ⚒️ Linting and Building Documentation Locally
+
+After writing up the documentation, you may want to lint and build the documentation
+locally to ensure that it looks good and is free of errors.
+
+If you're unable to build it locally that's okay as well, as you will be able to
+see a preview of the documentation on the pull request page.

+## ⌨️ In-code Documentation
+
+The in-code documentation is largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code and is hosted by [Read the Docs](https://readthedocs.org/).
+
+For the API reference to be useful, the codebase must be well-documented. This means that all functions, classes, and methods should have a docstring that explains what they do, what the arguments are, and what the return value is. This is a good practice in general, but it is especially important for LangChain because the API reference is the primary resource for developers to understand how to use the codebase.
+
+We generally follow the [Google Python Style Guide](https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings) for docstrings.
+
+Here is an example of a well-documented function:
+
+```python
+
+def my_function(arg1: int, arg2: str) -> float:
+    """This is a short description of the function. (It should be a single sentence.)
+
+    This is a longer description of the function. It should explain what
+    the function does, what the arguments are, and what the return value is.
+    It should wrap at 88 characters.
+
+    Examples:
+        This is a section for examples of how to use the function.
+
+        .. code-block:: python
+
+            my_function(1, "hello")
+
+    Args:
+        arg1: This is a description of arg1. We do not need to specify the type since
+            it is already specified in the function signature.
+        arg2: This is a description of arg2.
+
+    Returns:
+        This is a description of the return value.
+    """
+    return 3.14
+```
+
+### Linting and Formatting
+
+The in-code documentation is linted from the directories belonging to the packages
+being documented.
+
+For example, if you're working on the `langchain-community` package, you would change
+the working directory to the `langchain-community` directory:
+
+```bash
+cd [root]/libs/langchain-community
+```
+
+Set up a virtual environment for the package if you haven't done so already.
+
+Install the dependencies for the package.
+
+```bash
+poetry install --with lint
+```
+
+Then you can run the following commands to lint and format the in-code documentation:
+
+```bash
+make format
+make lint
+```

+# Repository Structure
+
+If you plan on contributing to LangChain code or documentation, it can be useful
+to understand the high level structure of the repository.
+
+LangChain is organized as a [monorep](https://en.wikipedia.org/wiki/Monorepo) that contains multiple packages.
+
+Here's the structure visualized as a tree:
+
+```text
+.
+├── cookbook # Tutorials and examples
+├── docs # Contains content for the documentation here: https://python.langchain.com/
+├── libs
+│   ├── langchain # Main package
+│   │   ├── tests/unit_tests # Unit tests (present in each package not shown for brevity)
+│   │   ├── tests/integration_tests # Integration tests (present in each package not shown for brevity)
+│   ├── langchain-community # Third-party integrations
+│   ├── langchain-core # Base interfaces for key abstractions
+│   ├── langchain-experimental # Experimental components and chains
+│   ├── partners
+│       ├── langchain-partner-1
+│       ├── langchain-partner-2
+│       ├── ...
+│
+├── templates # A collection of easily deployable reference architectures for a wide variety of tasks.
+```
+
+The root directory also contains the following files:
+
+* `pyproject.toml`: Dependencies for building docs and linting docs, cookbook.
+* `Makefile`: A file that contains shortcuts for building, linting and docs and cookbook.
+
+There are other files in the root directory level, but their presence should be self-explanatory. Feel free to browse around!
+
+## Documentation
+
+The `/docs` directory contains the content for the documentation that is shown
+at https://python.langchain.com/ and the associated API Reference https://api.python.langchain.com/en/latest/langchain_api_reference.html.
+
+See the [documentation](./documentation) guidelines to learn how to contribute to the documentation.
+
+## Code
+
+The `/libs` directory contains the code for the LangChain packages.
+
+To learn more about how to contribute code see the following guidelines:

 2. A search tool. This will let it easily answer questions that require up to date information.

+    "- Function calling: This is when the LLM is finetuned to be able to not just generate a completion, but also generate a function call. The functions the LLM can call are generally passed as extra parameters to the model API. The function names and descriptions should be treated as part of the prompt (they usually count against token counts, and are used by the LLM to decide what to do).\n",
+    "- Tool calling: A technique similar to function calling, but it allows the LLM to call multiple functions at the same time.\n",
+    "- JSON mode: This is when the LLM is garunteed to return JSON.\n",
+    "\n",
+    "\n",
+    "\n",
+    "Different models may support different variants of these, with slightly different parameters. In order to make it easy to get LLMs to return structured output, we have added a common interface to LangChain models: `.with_structured_output`. \n",
+    "\n",
+    "By invoking this method (and passing in a JSON schema or a Pydantic model) the model will add whatever model parameters + output parsers are necessary to get back the structured output. There may be more than one way to do this (eg function calling vs JSON mode) - you can configure which method to use by passing into that method.\n",

The term \"low latency\" refers to the model\\'s ability to process and respond to inputs quickly, with minimal delay.\\n\\nThe importance of low latency in LLMs can be explained through the following points:\\n\\n1. Improved user experience: In real-time applications such as chatbots, virtual assistants, and interactive games, users expect quick and responsive interactions. Low latency LLMs can provide instant feedback and responses, creating a more seamless and engaging user experience.\\n\\n2. Better decision-making: In time-sensitive scenarios, such as financial trading or autonomous vehicles, low latency LLMs can quickly process and analyze vast amounts of data, enabling faster and more informed decision-making.\\n\\n3. Enhanced accessibility: For individuals with disabilities, low latency LLMs can help create more responsive and inclusive interfaces, such as voice-controlled assistants or real-time captioning systems.\\n\\n4. Competitive advantage: In industries where real-time data analysis and decision-making are crucial, low latency LLMs can provide a competitive edge by enabling businesses to react more quickly to market changes, customer needs, or emerging opportunities.\\n\\n5. Scalability: Low latency LLMs can efficiently handle a higher volume of requests and interactions, making them more suitable for large-scale applications and services.\\n\\nIn summary, low latency is an essential aspect of LLMs, as it significantly impacts user experience, decision-making, accessibility, competitiveness, and scalability. By minimizing delays and response times, low latency LLMs can unlock new possibilities and applications for artificial intelligence in various industries and scenarios.')"

+    "This notebook demonstrates how to use Kinetica to transform natural language into SQL\n",

+    "\n",
+    "## Overview\n",
+    "\n",
+    "With the Kinetica LLM workflow you create an LLM context in the database that provides\n",
+    "information needed for infefencing that includes tables, annotations, rules, and\n",
+    "samples. Invoking ``ChatKinetica.load_messages_from_context()`` will retrieve the\n",
+    "context information from the database so that it can be used to create a chat prompt.\n",
+    "\n",
+    "The chat prompt consists of a ``SystemMessage`` and pairs of\n",
+    "``HumanMessage``/``AIMessage`` that contain the samples which are question/SQL\n",
+    "pairs. You can append pairs samples to this list but it is not intended to\n",
+    "facilitate a typical natural language conversation.\n",
+    "\n",
+    "When you create a chain from the chat prompt and execute it, the Kinetica LLM will\n",
+    "generate SQL from the input. Optionally you can use ``KineticaSqlOutputParser`` to\n",
+    "execute the SQL and return the result as a dataframe.\n",
+    "\n",
+    "Currently, 2 LLM's are supported for SQL generation: \n",
+    "\n",
+    "1. **Kinetica SQL-GPT**: This LLM is based on OpenAI ChatGPT API.\n",
+    "2. **Kinetica SqlAssist**: This LLM is purpose built to integrate with the Kinetica\n",
