Open-source search infrastructure for AI apps that need vector, full-text, regex, and metadata search.
Freemium / Open source / API
Python framework for building typed AI agents, realtime voice, image generation, embeddings, and multi-agent workflows.

Pydantic AI is a Python toolkit for building AI agents with typed inputs, outputs, dependencies, tools, message history, citations, retries, and batch processing. It supports multimodal input, direct model requests, and patterns for multi-agent workflows.
It also includes realtime speech-to-speech, image generation, embeddings, and interfaces for web chat UI and a command-line interface. The framework covers agent skills, workspaces, persistence, durable execution, guardrails, and observability integrations.
It is aimed at developers who want to build agentic applications with Python and Pydantic-style type safety across models, tools, and interfaces.
