Shared compatibility
- Python · agent-framework: Python runtime · pydantic-ai: Python runtime
Choose agent-framework if…
- Requirements: Python version 3.6 or newer is required for Python installations.; The .NET Core SDK must be installed for utilizing the .NET packages..
- Tags unique to agent-framework: agentic-ai, agents, multi-agent, orchestration.
- Choose agent-framework if your project requires support for both Python and .NET, allowing you to develop across different ecosystems.
When NOT to use agent-framework
- Avoid using the agent-framework if your team does not have proficiency in either Python or.NET, as this may cause difficulties in leveraging its features effectively.
- Do not opt for agent-framework if you only need lightweight support for AI agents without a comprehensive orchestration and deployment framework.
Choose pydantic-ai if…
- Tags unique to pydantic-ai: genai, harness, harness-engineering, llm.
- Also covers Computer Vision, Speech & Audio.
- When you need a typed and extensible agent loop that can be easily integrated into different interfaces such as web frontends, terminals, voice calls, and GitHub Actions.
When NOT to use pydantic-ai
- If your project does not require a typed agent loop or if you prefer a more loosely typed framework.
- When you are working in a language other than Python, as Pydantic AI is specifically designed for Python.
- If you need a tool that focuses solely on a specific interface or model without the need for extensibility across multiple interfaces.
