Pydantic AI is a typed Python SDK for building AI agents and LLM applications. It provides an extensible agent loop, multi‑modal capabilities, and a harness for durable, long‑running workflows.

Use cases

• build type‑safe AI agents that can plan, remember, and call tools
• create real‑time voice assistants or chatbots with streaming responses
• run multi‑modal pipelines that generate images, embeddings, or audio
• orchestrate long‑running research or coding tasks with durable execution
• integrate agents into web front‑ends, CLI tools, or serverless functions

When to choose

• you need strong type safety and validation for agent inputs/outputs
• your application requires durable, resumable execution across restarts
• you want a single framework that works across CLI, web, and voice interfaces
• you need built‑in support for multiple models, embeddings, and image generation
• you prefer a Python‑first SDK with extensive extensibility via capabilities

When to avoid

• you are working in a non‑Python ecosystem or need low‑level performance
• your use case is a simple one‑shot API call without agent orchestration
• you require a lightweight library without the additional harness features
• you need built‑in GPU‑accelerated training rather than inference only
