For those following the #rstats {ellmer} package: I got the chat_databricks() and chat_snowflake() providers working with tool calling this past week. IMHO this means these providers are no longer toys: they can be used with RAG (via {ragnar}) and other complex tasks like @simonpcouch.com's {btw}.

With so many LLMs available to help you write #RStats code, how do you choose the right one? We put a handful of models to the test using the vitals package, our framework for robust LLM evaluation. Check out the analysis on the Posit Blog! posit.co/blog/r-llm-e...

I think MCP will be a big deal for a lot of folks in my orbit. Think of it as a way to constrain LLM output to more specifically match your needs & use cases. That could be better understanding your data, or focusing on a set of casual inference tasks supported by your favourite libraries.

Introducing acquaint, an R package that turns your R sessions into a Model Context Protocol (MCP) server. This allows MCP-enabled tools like Claude Desktop and Claude Code to run #rstats code _in your active R sessions_ to explore objects, read documentation, etc. posit-dev.github.io/acquaint/

Just made promptdown public. It's a plain-text interface for working with LLMs using literate programming. See and edit the full prompt each turn. No cramped input boxes, no hidden context, no append-only chat. Still early alpha, feedback welcome! github.com/t-kalinowski...
