Deep dives
Inception of LangChain
LangChain was created to address the challenges developers faced in working with large language models (LLMs) for building AI-driven applications. Initially an open-source project, it emerged just before the launch of ChatGPT in late 2022 when developers began needing better tools for handling LLMs. Eric Fries, a founding engineer, noted that the original library focused on simplifying various stages of interaction with LLMs, including output parsing and building agentic loops. This adaptability has allowed LangChain to evolve alongside the technology, integrating user feedback to enhance usability in production applications.
