It provides a standard interface for various components and abstractions:
LLMs: The backbone of LangChain, LLMs like OpenAI’s GPT-3 or GPT-4 provide the core capabilities for understanding and generating language. They are trained on vast datasets to produce coherent and contextually relevant text.
Prompt Templates: These templates structure the input to LLMs, maximizing their effectiveness in understanding and responding to queries. By designing effective prompts, developers can guide the LLMs to produce desired outputs.
Output Parsers: These components refine the language generated by LLMs into formats that are useful and relevant to specific tasks, enhancing the overall user experience.
Vector Store: This component handles the embedding of words or phrases into numerical vectors, which is essential for tasks involving semantic analysis and understanding language nuances.
Agents: Agents are decision-making components that determine the best course of action based on input, context, and available resources. They enable LLMs to interact intelligently with their environment.
