Vercel AI SDK 3.3

This post introduces experimental tracing with OpenTelemetry for the Vercel AI SDK, enabling detailed observability of AI function calls. It also adds experimental support for multi-modal file attachments (FileList or URLs) to the `useChat` hook and introduces the `useObject` hook for streaming structured object generation to the client, demonstrated with a Zod schema for expense tracking. New model providers (AWS Bedrock, Chrome AI) and additional LLM settings are also included.
