We have summer internships y'all! Come work at Posit on the PyData, tidymodels, shiny, or Connect teams: grnh.se/tigz810a3us. You will have an awesome time, learn a ton, and help advance our open source and pro tools 🧰 #rstats #pydata

The March edition of posit::glimpse() is here! 🚀 Key updates include Posit AI, a new assistant in RStudio, Pointblank for synthetic data for #Python, mirai v2.6.0: 50% faster async #RStats ⚡, Positron's PDF viewer + Jupyter support, and more. Read the full roundup: posit.co/blog/glimpse...

Accessibility is hard and nuanced but oh so important. Quarto takes another step forward thanks to Gordon Woodhull. quarto.org/docs/blog/po...

Interesting writeup from Rich (of GT fame) on what Wes McKinney has unlocked with rise of LLMs. posit.co/blog/the-pro.... I have thoughts about what this type of development means for teams and processes. Need to share some of them soon! Moving target!

The newest edition of posit::glimpse() is here! 🚀 Read a roundup of major #RStats & #Python updates: ggplot2 4.0.0, dplyr 1.2.0, ellmer 0.4.0, Positron native Jupyter Notebook support , and more. 🎟️ Plus, registration for posit::conf(2026) is officially OPEN! Find it here: posit.co/blog/posit-g...

I really love querychat as a way to leverage the flexibility of LLMs but in a safe controlled way. Building dashboards in Python? This excellent walk through by Veerle is _worth_ checking out. youtu.be/AntqhLhw4BM?... If you "just wish it had the option to..." PLEASE REACH OUT! WE ARE LISTENING!

Surprise I wrote another quarto revealjs extension. Now giving you more fragments to use! Easy to use fragments with conventional syntax. Works on headers, whole slides and on a letter-by-letter basis github.com/EmilHvitfeld... #quarto

I think the Turing test with real world implications is -- can an AI agent _appear_ more productive than an apathetic human in a broken system _appears_.

Amazing post on an amazing session. Thank you so much for sharing Emily!

New data from @sara-altman.bsky.social & @simonpcouch.com, using the vitals and ellmer packages, looks at LLM performance metrics for #RStats. 👀 Sneak peek: Claude Opus 4.5, Claude Sonnet 4.5, & OpenAI GPT-5 lead in generating correct R code. Read the full breakdown: posit.co/blog/r-llm-e...

Isabel Z is killing it giving a talk on data tools as the keynote speaker at pydata Boston! Let’s go!

I put together two roundups from posit::conf(2025): • Shiny talks + full workshop materials shiny.posit.co/blog/posts/c... • Quarto talks playlist and summaries quarto.org/docs/blog/po...

Introducing bluffbench, a new tool to evaluate how well LLMs actually see data plots. When we trick LLMs with secret #RStats transformations, they can miss the visual contradiction. bluffbench helps us measure this "blind spot" in AI coding agents. Learn more: posit.co/blog/introdu...

I am looking forward to PyData Boston in a few weeks. If anyone is going and wants to meet up please let me know. I will be sitting at the Posit table quite a bit of the time. I went to the last few PyData NYCs so it will be interesting to see how it differs. pydata.org/boston2025

We're hiring an open-source #python developer focused on modeling APIs! tidyverse.org/blog/2025/11... #numpy #scipy #scikitlearn

How long before I can get a credit card with a reward program paying out in Anthropic or OpenAI token credits?

In case you missed it in all the posit::conf 2025 content, checking out part 3 of Veerle van Leemput's series on building your first AI powered app is worth checking out! shiny.posit.co/blog/posts/s...

Part two of Veerle van Leemput's exploration of LLMs is out. Her exposition is so clear and easy to follow even if you are not likely to use Shiny its worth checking out! shiny.posit.co/blog/posts/s...

Introducing Databot: an AI assistant for exploratory data analysis in #Python and #RStats! A research preview in Positron, Databot is a tireless pair programmer to help you explore data. Learn more about this tool and our philosophy behind it: 🤖 posit.co/blog/introdu... ⚠️ posit.co/blog/databot...

Finally got Glimpse out focused on what the Posit open source team has been up to. Turns out its quite a bit! posit.co/blog/posit-g... I continue to be happy with the approach we (Posit) are taking with LLMs and AI. Too impactful to ignore but focus on useful and safe as much as possible.

You might be in a certain kind of family if... as leftovers are being put away in the fridge there is an involved discussion on if the fridge is LIFO or FIFO and if that is family member specific. Then the undeniable trump card is played and its really MDFO (Most Delicious) for everyone.

This is fantastic! Really looking forward to using this … like tomorrow! Let’s gooooo!

Announcing a new blog series on LLMs from @veerle.hypebright.nl! Part 1: "What LLMs Actually Do (and What They Don't)" breaks down complex concepts like transformers, hallucinations, and RAG in simple terms. Check it out here: shiny.posit.co/blog/posts/s... #RStats #LLM #PythonProgramming

Testing work or apps that leverage LLMs is disturbingly difficult. At Posit we have been exploring how to do this as we explore RESPONSIBLE usage of LLMs in data science. Sara and Simon share some findings about which models play nice with Pandas. 🐼 posit.co/blog/python-...

Ever wonder about the mind behind Pandas & Apache Arrow? 🤔 Ep. 2 of #TheTestSet (Part 1!) unpacks @wesmckinney.com's journey, including his speedrunning past! What makes good tools good? 🎧 Listen at thetestset.co, on Spotify, or Apple Podcasts #Python #DataEngineering #OpenSource #PodcastLaunch

Let’s be clear. LLMs do not hallucinate. LLMs are not trying to be correct, they are trying to be plausible.

Love seeing the communities work on Posit's blog. If you have an awesome Quarto or Shiny blogpost you think you are missing ping me and lets see if we can work it out! posit.co/blog/race-st...

Quarto Iconify 3.0.0 is there! Set your own global default values via the YAML frontmatter because sometimes you want things to get upside down all at once 🙃 github.com/mcanouil/qua... #Quarto #Iconify #HTML

So happy to work at a company that shows up for open source! Lets go!!!

Love it, or hate it LLMs are going to have a profound impact on software development and data science. At Posit I have been helping the team grapple with the tech. I wrote up our process and experiences with it. Would love to hear about other orgs have engaged with them. posit.co/blog/llm-hac...

Posit has been up to lots of exciting stuff. I wrote a short overview of it as a Glimpse Newsletter. Lots of LLM/AI (its important whether you love it or hate it)... Beyond product announcements, there are also some great learning resources. Let me know what you think. posit.co/blog/posit-g...

Simon has been killing it, building packages and exploring the use of AI/LLMs in R. It seems like deciding on which base model to use should be straightforward forward, but even that takes thoughtfulness, a systematic approach and is a (fast) moving target!

New on my blog: OpenAI dropped a trio of models yesterday that they claim result from "focusing closely on real-world developer needs." I was curious whether this might mean stronger #rstats coding performance. www.simonpcouch.com/blog/2025-04...

We are delighted to announce the release of ellmer, an R package for accessing the power of LLMs in R! ellmer supports a variety of model providers. Chat, tool call, stream API calls, extract structured data, and more! Learn about it here: posit.co/blog/announc... #RStats #AI #LLM

Meet gander, a chat interface for R data scientists🪿 gander automatically incorporates context from your #rstats environment and surrounding code and can be used with any model supported by ellmer in either RStudio or Positron. Read more: simonpcouch.github.io/gander/

Messing with CSS and doing it project by project, and format by format, across bigger organizations has been a nightmare. I have been a huge flag carrier at Posit for brand.yml to work help solve it. Sara walks us through the first steps on the road. posit.co/blog/unified...

So excited we are joining this effort at Posit!

I just posted this list of Shiny Posit Conf 2024 talks shiny.posit.co/blog/posts/c... to match the set Mine and Charlotte put together for Quarto quarto.org/docs/blog/po... !

Really looking forward to the new features coming in Quarto v1.6. Brand.yml in particular!
