This is as good a "You might not need Vercel AI SDK" post as you'll read.

I work on internal LLM tooling for a F100 at $DAYJOB and was nodding vigorously while reading this, especially when it comes to things like letting users freely switch between models, and the affordances you need to be able to provide good UX around streaming and tool calling, which seem barely thought-out in things like the MCP spec (which at least now has a way to get friendly display names for tools since the last time I looked at it).
