There was a problem hiding this comment.
Minor notes, but overall a very successful refactor!

This PR is a major update to BlockNote AI 🔥
Overview
streamText+ tool calling by default instead of Object GenerationChatandtransportconcepts)PromptBuilders have been redesigned to split the creation of the required data (PromptBuilderInputDataand creation / modification of the LLMMessagesBackend pattern
We've revisited the old solution where BlockNote made direct calls to LLMs from the client using the Vercel AI SDK (or via a proxy).
Instead it's now recommended to send request to your backend. There, you can then invoke your LLM (potentially adding more context, tools, RAG, etc). While a bit more work to set up, this architecture is more inline with the Vercel SDK and unlocks more powerful workflows.
Breaking changes
See the updated docs and backend integration guide for an overview of the new APIs. The main breaking change is that
createAIExtensionnow accepts atransportthat provides the integration with your backend.We now recommend to use the Vercel AI SDK on your backend. For alternative options, see the backend integration guide. The previous proxy-based approach is still available and explained in the backend guide.
