LangChain is the open-source SDK for building reliable, production-ready LLM applications by chaining together models, data sources, and external tools.

This is your core framework for developing advanced LLM applications, available in Python and TypeScript. LangChain simplifies complex workflows: it abstracts the boilerplate for creating Agents, Chains, and Retrieval systems (RAG). The SDK offers a massive ecosystem of over 1000 integrations (OpenAI, Anthropic, various vector stores), ensuring you can swap components without rewriting core logic. Use it to quickly move from prototype to a dependable production system, for example, by building a sophisticated agent that uses a search tool and a vector database for real-time data access.

## Recent Public Talks and Demos

### [CopilotBuilder - Democratizing Generative AI agent creation for every organization](https://columbus.aitinkerers.org/talks/rsvp_AwGKD4NWtwk)

We will demo our platform that we have been working on for over 9 months that allows individuals and organizations of any technical competency to create and deploy incredibly sophisticated AI-based agents (called "Copilots"). We will walk thru our application architecture and discuss the challenges that we have faced over the past year to create the functionality that the current platform has.
