Lang Chain serves as an open source framework designed to facilitate the creation of applications powered by language models (LLMs). By streamlining the chaining of prompts, interaction with external data, and enabling context remembrance, Lang Chain significantly reduces the boilerplate code that developers would typically need to manage when working with LLMs.
Key Features of Lang Chain
LLM Support: Lang Chain supports both closed-source models like GPT-4 and open-source alternatives like Llama 3. Developers need merely to plug in their API keys to get started.
Dynamic Prompts: The framework offers prompt templates that allow for customizable querying, making it easier to adapt to various tasks dynamically.
