The newest release of Posit Assistant, an agent for coding and data analysis, includes a "data cleaning mode." When enabled, the agent will run quality checks and surface decisions about e.g. import issues, factor levels, etc to the user. In the AI Newsletter: opensource.posit.co/blog/2026-05...

RStudio now has next edit suggestions! I wrote a bit about how they work and have open-sourced the eval we used to engineer the system's prompt: www.simonpcouch.com/blog/2026-03...

Today we're releasing AI for RStudio. It's really, really good—I'd encourage you to point it at the messiest data sources you have and see what it can do. www.simonpcouch.com/blog/2026-03...

Join us on Tuesday at the Data Science Lab 🧪 We are joined by @sara-altman.bsky.social, who will show us how to explore and analyze data using AI assistants in #RStats or #Python! Feb 3 @ 12 pm ET: pos.it/dslab

In this week's newsletter, @simonpcouch.com and I share some interesting tidbits from Claude's constitution, an estimate of the electricity use of coding agents, and an update on our plot interpretation work.

"LLMs [only] do a great job at interpreting plots that _don't_ contradict their expectations—it's sort of antithetical to the spirit of science." - @mike-thomas.bsky.social. Thanks for the coverage, yall! More on @sara-altman.bsky.social and I's bluffbench eval: posit.co/blog/llm-plo...

More on LLMs and plot interpretation: they do fine in normal conditions, but struggle when the plot conflicts strongly with their priors. @simonpcouch.com and I investigated why and what might help: posit.co/blog/llm-plo...

Thinking about running local models with coding agents like Positron Assistant? 💻 A new evaluation by @simonpcouch.com and @sara-altman.bsky.social suggests we aren't there yet. Between hardware hurdles and performance gaps, hosted models are still the best bet for now. posit.co/blog/local-m...

GPT 5.2 is now included in our R code generation eval! The -Pro version is slightly SoTA at a substantially higher price point than similar performers. Read more: skaltman-model-eval-app.share.connect.posit.cloud

🗞️ New edition of the Posit AI Newsletter is up on the Posit blog! Curated by @sara-altman.bsky.social and @simonpcouch.com, this week covers LLM introspection, an RStudio coding agent, custom providers in Positron Assistant, and more. Read the latest: posit.co/blog/2025-11...

🚀 The 3rd edition of the Posit AI Newsletter is out now! Curated by @sara-altman.bsky.social and @simonpcouch.com, this biweekly newsletter keeps you up to speed with #AI. This week: the #Claude degradation incident, posit::conf AI talks, and what "agents" actually are. 📬 posit.co/blog/2025-09...

So stoked to share about the first release of the Posit AI Newsletter! @sara-altman.bsky.social and I have been working on a pilot of this newsletter internally for a few months now—an opinionated and pragmatic snapshot of AI news released every two weeks. First edition: posit.co/blog/2025-08...
