AutoGen explained: Microsoft's multi-agent conversation framework, code-execution agents for data analysis, the AG2 fork, and AutoGen vs CrewAI vs LangGraph.

pip install autogen-agentchat autogen-ext[openai]

CrewAI multi-agent framework explained: role-based crews, Flows for deterministic pipelines, CrewAI vs LangGraph, and when multi-agent is overkill.

pip install crewai

LangGraph: low-level agent framework from LangChain for building stateful, multi-step data pipeline agents with explicit graphs.
