What is an AI agent framework?

An AI agent framework provides the scaffolding to build AI systems that can reason about tasks, use tools, maintain memory, and take actions autonomously. Frameworks include LangChain-based, custom agent loops, and multi-agent orchestrators.

Which AI agent framework should I start with?

Start with a simple ReAct agent framework if you are new to agents. For production systems, choose a multi-agent framework with built-in error handling, logging, and human-in-the-loop checkpoints.

Can AI agents work with existing APIs?

Yes. Most agent frameworks support tool-use patterns where agents can call REST APIs, query databases, and interact with external services through defined tool interfaces.
