SE Radio 676: Samuel Colvin on the Pydantic Ecosystem

·1 hr 2 min·5 clips
NASA uses Pydantic to process James Webb Space Telescope imagery, and banks rely on it for interbank transfer validation.
Samuel Colvin discusses the Pydantic ecosystem, including Pydantic for data validation in Python, Pydantic AI for LLM interactions, and LogFire for observability. He covers the rewrite of Pydantic in Rust for performance gains, critiques the engineering quality of AI frameworks, and explains how LogFire uses OpenTelemetry and AST instrumentation. The conversation highlights real-world applications from NASA to banking and upcoming announcements from Pydantic.
