End-to-end AI engineering stack We started as a Python validation library. We're now the AI engineering company behind the stack that teams use to build with GenAI in production. Pydantic AI. Pydantic Logfire. Pydantic Evals. AI Gateway. Each tool is useful on its own. Together, they cover the full lifecycle of building with AI: from structured outputs and agent logic, to observability, evaluation, and cost tracking. Trusted by developers building at scale. Developer experience first, always. Pydantic, because AI is still just engineering.
