## LangChain
![langchain logo](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5u34aur48tj25f61uhqy.png)

Developed by [Harrison Chase](https://twitter.com/hwchase17) and debuted in October 2022, [LangChain](https://www.langchain.com/) serves as an open-source platform designed for constructing sturdy applications powered by LLMs, such as chatbots like ChatGPT and various tailor-made applications.
LangChain seeks to equip data engineers with an all-encompassing toolkit for utilizing LLMs in diverse use cases, including chatbots, automated question answering, text summarization and beyond.

The above image shows how LangChain handles and processes information to respond to user prompts. Initially, the system starts with a large document containing a vast array of data. This document is then broken down into smaller, more manageable chunks.

These chunks are subsequently embedded into vectors - a process that transforms the data into a format that can be quickly and efficiently retrieved by the system. These vectors are stored in a vector store, essentially a database optimized for handling vectorized data.

When a user inputs a prompt into the system, LangChain queries this vector store to find information that closely matches or is relevant to the user's request. The system employs large LLMs to understand the context and intent of the user's prompt, which guides the retrieval of pertinent information from the vector store.

Once the relevant information is identified, the LLM uses it to generate or complete an answer that accurately addresses the query. This final step culminates in the user receiving a tailored response, which is the output of the system's data processing and language generation capabilities.

## SingleStore Notebooks

## LlamaIndex
![llamaindex logo](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/98rabtt1wt9esmoxcpui.png)

[LlamaIndex](https://www.llamaindex.ai/) is an advanced orchestration framework designed to amplify the capabilities of LLMs like GPT-4. While LLMs are inherently powerful, having been trained on vast public datasets, they often lack the means to interact with private or domain-specific data. LlamaIndex bridges this gap, offering a structured way to ingest, organize and harness various data sources - including APIs, databases and PDFs.

By indexing this data into formats optimized for LLMs, LlamaIndex facilitates natural language querying, enabling users to seamlessly converse with their private data without the need to retrain the models. This framework is versatile, catering to both novices with a high-level API for quick setup, and experts seeking in-depth customization through lower-level APIs. In essence, LlamaIndex unlocks the full potential of LLMs, making them more accessible and applicable to individualized data needs.

### How LlamaIndex works?
LlamaIndex serves as a bridge, connecting the powerful capabilities of LLMs with diverse data sources, thereby unlocking a new realm of applications that can leverage the synergy between custom data and advanced language models. By offering tools for data ingestion, indexing and a natural language query interface, LlamaIndex empowers developers and businesses to build robust, data-augmented applications that significantly enhance decision-making and user engagement.

LlamaIndex operates through a systematic workflow that starts with a set of documents. Initially, these documents undergo a load process where they are imported into the system. Post loading, the data is parsed to analyze and structure the content in a comprehensible manner. Once parsed, the information is then indexed for optimal retrieval and storage.

This indexed data is securely stored in a central repository labeled "store". When a user or system wishes to retrieve specific information from this data store, they can initiate a query. In response to the query, the relevant data is extracted and delivered as a response, which might be a set of relevant documents or specific information drawn from them. The entire process showcases how LlamaIndex efficiently manages and retrieves data, ensuring quick and accurate responses to user queries.

## Llama 2
![Llama2 logo](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/x3ct40fb9wzyoe3v8zqn.png)

[Llama 2](https://about.fb.com/news/2023/07/llama-2/) is a state-of-the-art language model developed by Meta. It is the successor to the original LLaMA, offering enhancements in terms of scale, efficiency and performance. Llama 2 models range from 7B to 70B parameters, catering to diverse computing capabilities and applications. Tailored for chatbot integration, Llama 2 shines in dialogue use cases, offering nuanced and coherent responses that push the boundaries of what conversational AI can achieve.

Llama 2 is pre-trained using publicly available online data. This involves exposing the model to a large corpus of text data like books, articles and other sources of written content. The goal of this pre-training is to help the model learn general language patterns and acquire a broad understanding of language structure. It also involves supervised fine-tuning and reinforcement learning from human feedback (RLHF).

One component of the RLHF is rejection sampling, which involves selecting a response from the model and either accepting or rejecting it based on human feedback. Another component of RLHF is proximal policy optimization (PPO) that involves updating the model's policy directly based on human feedback. Finally, iterative refinement ensures the model reaches the desired level of performance with supervised iterations and corrections.
