Explore the major architectural changes and new capabilities in AI SDK 5 through this 14-minute conference talk from an AI meetup in Wrocław. Learn why the Vercel AI SDK team decided on a complete rewrite rather than incremental updates to address the challenges of diverging provider APIs and the evolving landscape of multimodal AI models. Discover the three core pillars of AI SDK 5's architecture: a revamped provider specification supporting ordered multimodal outputs and provider-executed tools, a fully type-safe UI and chat layer with typed metadata and tool calls, and new controls for creating sophisticated agentic tool-calling loops including the `prepare` step and `stopWhen` conditions. Understand how these changes enable building complex, maintainable UI components while providing enhanced chat capabilities with swappable transports and UI framework independence. Get insights into the future roadmap including improved telemetry and image editing capabilities, presented by Lars Grammel from the Vercel AI SDK team.
