LangChain
LangChain is a framework for developing applications powered by large language models (LLMs). It provides modular components for chains, agents, and memory management.
Key Concepts
- LLM interfaces
- Prompt templates
- Chains and agents
- Document loaders
- Vector stores and embeddings
Common Use Cases
- Chatbot applications
- RAG (Retrieval Augmented Generation)
- Question answering systems
- Autonomous agents
- Document processing
Best Practices
- Use proper prompt engineering
- Implement proper memory
- Handle errors gracefully
- Cache LLM responses
- Test with mock LLMs
