The honest brief
Agno
Built for speed and scale — agents instantiate near-instantly with low memory, and ship to production via the bundled AgentOS FastAPI runtime.
- Fast agent instantiation, low memory use
- Multi-modal agents and agent teams
- Bundled AgentOS production runtime
- Model- and provider-agnostic
- Younger than LangChain and LlamaIndex
- Rapid changes since the Phidata rename
- Smaller community and ecosystem
Pydantic AI
From the Pydantic team, so agent outputs are validated by the same library most Python LLM apps already use for schemas.
- Type-safe, validated structured outputs
- From the trusted Pydantic team
- Model-agnostic, MIT-licensed
- MCP support, Logfire observability
- Python-only
- Younger than LangChain/LlamaIndex
- Smaller ecosystem of integrations
When to pick which
Both cover Agent framework and Tool / function calling.
Pick Agno if you need Multi-agent orchestration, Agent memory, RAG pipeline, and App / agent deployment.
- Multi-agent orchestration (primary capability)
- Agent memory (secondary capability)
- RAG pipeline (secondary capability)
- App / agent deployment (primary capability)
Pick Pydantic AI if you need Multi-model access, LLM evaluation, LLM observability, and Structured extraction.
- Multi-model access (secondary capability)
- LLM evaluation (secondary capability)
- LLM observability (secondary capability)
- Structured extraction (secondary capability)
Pydantic AI leans on Agent framework and Tool / function calling as a headline capability; Agno treats them as secondary.
- Agent framework (primary capability)
