LangChain with OpenAI

Large Language Models frameworks

LangChain is a framework designed for developing applications powered by large language models (LLMs). It focuses on enabling these models to interact with their environment, perform tasks, and integrate with various data sources and APIs. Here are some key features and concepts of LangChain:

1. Modular Components: LangChain provides various building blocks for working with LLMs, including prompts, memory, chains, agents, and tools.
2. Chains: These are sequences of calls to LLMs or other utilities. For example, a chain could take user input, process it through an LLM to generate a response, and then use additional tools to refine or act on that response.
3. Agents: LangChain supports the creation of agents that use LLMs to determine which actions to take and in what order. Agents can utilize tools to perform tasks and answer questions.
4. Prompts and Prompt Engineering: LangChain allows for the easy creation and manipulation of prompts, which are essential for guiding the behavior of LLMs.
5. Memory: Memory modules help maintain context over interactions, which is crucial for creating more coherent and context-aware applications.
6. Integration with Data Sources: LangChain can connect to various data sources such as databases, APIs, and external tools, enabling LLMs to access and process real-world data.
7. Tool Use: The framework supports the integration of external tools and APIs…
