Build LLM apps with agents and RAG using a comprehensive framework that provides components for agent creation, chains, and retrieval-augmented generation pipelines over custom data.

Multiple LLM providers like OpenAI and Anthropic are supported for tool calling. The framework integrates with over 500 tools and providers to facilitate seamless agent interactions.

Retrieval-augmented generation with vector stores works by retrieving relevant documents from the store to provide context to the LLM. This enables advanced question answering over custom data.

The best way to create autonomous agents that use tools is by using the framework's ReAct agent capabilities. Agents can reason, interact with LLMs, and perform web searches or calculations.

A development framework is needed for memory management in chatbots to maintain conversation context effectively. This framework provides built-in memory management for production deployments.

Limitations when building ReAct agents for production deployments include managing the complexity of reasoning loops and tool integrations. The framework facilitates rapid prototyping to address these scaling challenges.
