## Summary

AI SDK 5 introduces major improvements including type-safe chat integration for React, Vue, Svelte, and Angular with separate UI and model messages for better state management. Key features include agentic loop control with stopWhen and prepareStep functions, experimental speech generation and transcription, enhanced tool capabilities with dynamic tools and provider-executed functions, and full-stack type safety. The release also adds data parts for streaming custom typed data, message metadata support, SSE streaming, and Zod 4 compatibility while maintaining the unified provider API for seamless model switching.
