Pydantic AI Compares Nine Python Agent Frameworks in 2026
Pydantic AI officially released a 2026 comparison of Python AI agent frameworks, evaluating nine frameworks item by item against criteria such as model switchability, durable execution after crashes, human approval, frontend and voice integration, MCP, and observability, and giving the applicable scenarios for each. The article states that Pydantic AI supports 30+ model providers, 8 durable execution engines (Temporal, DBOS, Prefect, Restate, AWS Lambda, Absurd, pgtask, Apache Airflow), 5 speech-to-speech providers, and 10 sandboxes, while also noting that it supports only Python, does not offer a hosted platform, and has fewer retrieval-related integrations than LangChain. The comparison also covers LangGraph/LangChain, OpenAI Agents SDK, Google ADK, Microsoft Agent Framework, Strands Agents, CrewAI, Claude Agent SDK, and Agno, and separately lists the two voice frameworks LiveKit Agents and Pipecat.
