Agent Frameworks

Microsoft AutoGen explained: multi-agent conversations, 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

DSPy for data pipelines: programmatic prompt optimization instead of hand-tuned prompts. Install steps, when it's worth the setup, and troubleshooting.

pip install dspy

Jev (TypeSafe AI) System One model setup: typed Choice/Score/Noul decisions via the jev-latest API, Python/JS SDKs, and how it fits an agent stack.

pip install typesafe-sdk

LangChain for data agents: what it's still good for, how it compares to LangGraph, install steps, safety notes, and common troubleshooting.

pip install langchain langchain-community

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

pip install langgraph

LlamaIndex for data agents: retrieval and indexing over your documents and databases. Install steps, LangChain comparison, limits, and troubleshooting.

pip install llama-index

OpenAI Agents SDK for data pipelines: the production successor to Swarm. Install steps, handoffs and guardrails, safety notes, and troubleshooting.

pip install openai-agents

Pydantic-AI: type-safe agent framework from the Pydantic team. Structured outputs, function tools, and dependency injection for production data agents.

pip install pydantic-ai

smolagents explained: Hugging Face's minimal agent library where a CodeAgent writes Python instead of JSON tool calls — a great fit for data analysis work.
