Official Resources

• Pydantic AI Documentation - Official documentation with guides, API reference, and examples.
• Pydantic AI Repository - Official GitHub repository. Agent framework with model-agnostic architecture, type safety, dependency injection, tool integration, and structured outputs.

Frameworks & Libraries

• pai-agent-sdk - Application framework for building AI agents with Pydantic AI. Provides full developer control without abstraction overhead, featuring environment-based architecture, resumable sessions, hierarchical subagents, and human-in-the-loop approval workflows.
• pydantic-deep - Python framework for building production-grade autonomous agents. Extends Pydantic AI with agent orchestration, task planning, subagent delegation, context management, and multiple backend support.
• pydantic-ai-middleware - Lightweight middleware library providing clean before/after hooks without imposed guardrail structure. Supports input/output processing, tool management, error handling, rate limiting, and audit logging.
• pydantic-ai-backend - File storage, sandbox backends, and console toolset for pydantic-ai agents. Includes LocalBackend, StateBackend, DockerSandbox, and pre-configured Docker runtimes.
• pydantic-ai-todo - Standalone task planning library for pydantic-ai agents. Provides read_todos and write_todos tools with flexible storage backends.
• subagents-pydantic-ai - Multi-agent orchestration library with dual-mode execution (sync/async), dynamic agent creation, and parent-child communication via ask_parent tool.
• summarization-pydantic-ai - Automatic conversation summarization and context management. Provides SummarizationProcessor for LLM-based summaries and SlidingWindowProcessor for zero-cost message trimming.
• pydantic-ai-filesystem-sandbox - Secure filesystem sandbox toolset with LLM-friendly errors. Provides sandboxing, read/write control, granular permissions, and human-in-the-loop approval workflows.
• pydantic-ai-skills - Standardized framework for building and managing Agent Skills. Features progressive disclosure, type-safe design, multi-directory support, and Anthropic Agent Skills compatibility.
• pydantic-collab - Multi-agent orchestration framework for building agent teams. Agents collaborate via handoffs, consultations (tool calls), and shared memory on top of pre-built and custom network topologies, Logfire observability included.

Templates & Boilerplates

• full-stack-fastapi-nextjs-llm-template - Production-ready project generator for AI/LLM applications. Combines FastAPI backend with Next.js 15 frontend, WebSocket streaming, JWT auth, multiple database options, and 20+ enterprise integrations.

Examples & Tutorials

• pydantic-ai-examples - Curated collection of examples demonstrating Pydantic AI usage including direct model requests, sentiment classification, dynamic classification, local models with Ollama, and conversation history management.
• pydantic-ai-rlm - Recursive Language Models with Pydantic AI.

Observability

• Pydantic Logfire - Observability platform for Python applications built by the Pydantic team. Provides logging, tracing, metrics with SQL query interface, OpenTelemetry foundation, and native Pydantic integration.
