Elevate Your AI game with LangChain: BigHub’s favorite new framework

At BigHub, our exploration into Langchain started with the simple OpenAI API calling. Yet the very first implementation provided us a glimpse into the transformative potential of this technology.

LangChain is an innovative framework that helps to utilize large language models (LLMs). LangChain is designed to be open-source and modular, making it a versatile tool for developers to create AI-powered language applications. It supports a plethora of programming languages, including Python and JavaScript, making it widely accessible and adaptable to various business needs​​​​.

Agent building toolkit

LangChain stands out with its flexible abstractions and a comprehensive toolkit that enables the development of context-aware applications capable of advanced reasoning. Ever heard of agents? Whether it's for crafting intuitive chatbots, developing sophisticated Q&A systems over documentation, summarizing large volumes of information, or acting as an intelligent co-pilot for a multitude of applications, LangChain provides an all-in-one framework with infinite use cases​​, a blueprint for building such agents.

The best things about LangChain are in our opinion ease of integration, modularity, and customizability. LangChain's adaptability is transformative for businesses seeking to maintain a competitive edge. When it's time to incorporate new advancements, LangChain's architecture makes it a breeze, eliminating the need for exhaustive overhauls.

Flowchart of processing steps

LangChain is not merely a framework; it’s a depiction of logic, a narrative of how a chatbot’s response journeys from a user’s input to a coherent, meaningful reply. In conventional terms, imagine a flowchart, where each node signifies a step in processing the user's input. LangChain breathes life into each of these nodes, offering a structured pathway from understanding user input, generating a corresponding search query in a vector database, fetching the results, and channeling them back through GPT (Generative Pre-trained Transformer) to furnish a well-informed response to the user.

Here's a simplistic illustration using the LangChain expression language, showcasing a common use case:

chain = (        


"query_text": itemgetter("query_text"),            

"chat_history": itemgetter("chat_history"),            

"sources": { "chat_history": itemgetter("chat_history")}                      

| RunnableLambda(lambda x: create_prompt(x["chat_history"]))      

| model_2        

| RunnableLambda(search_azure_cognitive_search),        


| RunnableLambda(lambda x: create_template_from_messages(x["chat_history"]))      

| model    


The snippet above is more than code; it’s a narrative of how LangChain facilitates a structured interaction, a step closer to human-like dialogues or thinking.
