Intro to LangChain: Top Enterprise Use Cases + Top Tools & Frameworks – AI&YOU #56

Industry use case: Rakuten, a large company with 70+ businesses, used LangChain’s OpenGPTs package to deliver an employee empowerment experience. It only took three engineers one week to get the initial platform up and running for Rakuten’s 32,000 employees, showcasing the speed and efficiency gains.

LangChain is a framework that simplifies the process of composing language models with external data to build powerful applications. Exploding in popularity over the past few months given the conversation around AI agents and agentic workflows (remember this term), LangChain provides a generic interface for connecting LLMs with structured data, documents, and APIs, making it easier than ever to create end-to-end agents that can understand and interact with enterprise knowledge.

In this week’s edition of AI&YOU, we are exploring insights from three blogs we published:

Intro to LangChain: enterprise use cases, top tools, and frameworks – AI&YOU #56

At its core, LangChain enables the seamless integration of language models with external data sources, unlocking a world of possibilities for leveraging the power of these cutting-edge AI systems.

One of the key strengths of LangChain lies in its ability to augment language models with retrieval capabilities. This approach, known as retrieval augmented generation (RAG), allows language models to access and incorporate relevant information from external data sources, such as databases, APIs, or document repositories.

By combining the language model’s natural language understanding and generation abilities with access to external knowledge, LangChain opens up new possibilties for building intelligent and context-aware applications for your enterprise.

Key Features of LangChain

1. Retrieval Augmented Generation for Language Models: Enables language models to leverage external data sources, enhancing their knowledge. Provides more accurate and informed responses, especially for applications requiring up-to-date or specialized information.

2. Composable Chains for Complex Workflows: Allows creation of complex workflows by composing reusable chains that encapsulate operations. Promotes code reusability and maintainability, enabling development of sophisticated applications with ease.

3. Off-the-Shelf Agents and Chains: Provides pre-built agents and chains covering a wide range of use cases. Accelerates development process, allowing developers to focus on higher-level tasks.

4. Support for Various Data Formats: Offers built-in support for diverse data formats, including text, PDFs, images, and structured data. Enables seamless integration with various information sources for comprehensive and data-driven solutions.

How LangChain Works Under the Hood

LangChain’s modular architecture enables developers to compose intricate chains that integrate language models with external data and custom logic. At its core are agents, tools, memory, and chains. Agents orchestrate workflows, determining which tools to use and how to combine their outputs. Tools perform specific tasks, such as querying databases or applying language models. Memory maintains context across steps, enabling informed decision-making. Chains define the sequence of operations and data flow.

LangChain provides pre-built chains for common use cases, while allowing custom chain creation. In a typical workflow, an agent retrieves relevant data using tools, passes it to a language model for processing, and evaluates the output, potentially iterating with additional tools or memory.

LangChain’s extensibility allows developers to create custom agents and tools to encapsulate domain-specific logic or integrate with proprietary systems, enabling tailored solutions that leverage large language models with structured data and business rules.

Why LangChain for Your Enterprise?

Enterprises are seeking ways to unlock the potential of large language models, but integrating them with complex business processes and structured data can be challenging. LangChain bridges this gap, offering a robust framework that connects language models with enterprise data and workflows.

10 Quotes on AI Agents From Harrison Chase, Co-Founder and CEO of LangChain

1. “I don’t think we’ve kind of nailed the the right way to interact with these agent applications. I think a human in the loop is kind of still necessary because they’re not super reliable. But if it’s in the loop too much, then it’s not actually doing that much useful thing. So, there’s kind of like a weird balance there.”

2. “Agents are like digital labor – capable of automatically browsing the web, navigating our files using our applications, and potentially even controlling our devices for us.”

3. “We’re basically constantly using a variety of different tools to help us with a given task. This is where agents are a bit different – instead of us using those tools, we just describe to an AI what the task is and what the end goal is, and then then it plans which tools it needs to use and how to use them and then it actually does it on its own.”

4. “Not only can they complete the task much quicker than we can, but in theory, we wouldn’t even need to know how to use these tools in the first place.”

5. “I think there’s probably like two places where it’s going. One is like more generic tool usage, so having, you know, humans specify a set of tools and then having agents use those tools in kind of like more open-ended ways.”
