Screenshot of Posit's blog post showing the Posit AI pricing breakdown. The service costs $20 per month and includes unlimited Next Edit Suggestions, a credit allowance for Posit Assistant described as covering 'a full month of typical use' for many users, and an automatic recharge option that charges additional money when the usage cap is reached. The Posit Assistant and Automatic Recharge sections are highlighted.

From the press release, this is a separate line item to Posit, not Anthropic. Your $20/mo gets a credit allowance for Posit Assistant, and if you exceed it, you pay Posit more through 'automatic recharge.' So yes, additive. You could be paying for Claude AND paying Posit for access to Claude

So the assistant that's free with your own key in one Posit IDE is $20/mo with rate limits and no key swapping in the other. NES feels less like a feature and more like the excuse for not just allowing a service integration.

Positron documentation page for Positron Assistant showing the section 'Positron AI agents' with highlighted text reading: 'The Positron AI tools are BYO-key, meaning that the tools can interact with a number of different model providers (e.g., Anthropic, AWS Bedrock, GitHub Copilot, or OpenAI).' This contrasts with Posit's RStudio announcement which does not support BYOK.

What's harder to square is that Posit Assistant already supports BYOK in Positron. But in RStudio, it's force-bundled with Next Edit Suggestions (NES) under the Posit AI subscription, and that bundle is the stated reason for no BYOK

The 'yet' is doing a lot of heavy lifting here. The blog says BYOK is being prioritized for Workbench in 2026. That still leaves RStudio Desktop and RStudio Server open source users, which is a sizable chunk of the community, locked into the managed service with no timeline for BYOK.

Screenshot of Posit’s blog post on posit.co highlighting the text: ‘Posit Assistant and NES in RStudio Desktop and RStudio Server require the managed Posit AI service and do not support custom model providers via Bring Your Own Key (BYOK).’

Posit finally adds AI to #RStudio after somehow sleeping through every alarm, and what lured them to the dark side wasn’t cookies. It was a $20/mo rate-limited ‘frontier-grade model’ that’s just Claude in a trench coat you can’t even bring your own key for. #rstats

"Cool" I hope 🙃

Small update on the python-on-iOS front: the unnamed notebook app now has a name -- Pyodios -- and a new trick.

Swap between a local Pyodide kernel and a remote Jupyter backend mid-session. Want offline? Stay local. Want GPU? Call home. No drama either way.

You may still want a computer; webRios' has some limitations as its built onto of webR (R's WebAssembly Distribution). Specifically, webRios does not support R package development, large scale data analysis (on-device memory limitations), or developing compiled code with R.

Already in the works; you'll even be able to create a GitHub repo in app!

Screenshot of the webRios documentation website at webrios.caffeinatedmath.com. The page shows the webRios app icon, the tagline 'R on Your Device,' version 1.1.1, and a description explaining it runs R code locally on iPhone and iPad via WebAssembly with no server required. Below are two iPhone mockups: the left showing an R console with code examples including print statements, warnings, errors, and ggplot2 commands; the right showing a plot gallery view with generated scatter plots and line charts.

webRios started as "what if #rstats just worked on your iPhone or iPad" and now it has a whole documentation site. Feels like the app grew up a little today.

Screenshot of webR-based Android application demonstrating inline graphics within the console window instead of having graphics being outsourced to the "Plots" tab.

Graphics are... inline!??

Android Studio IDE showing an AndroidManifest.xml file for an app called webrios, alongside a Pixel 8 Pro emulator running the app. The emulator displays an R console with several executed commands: basic arithmetic (1 + 1 returning 2), a message function printing 'Hello Mike!', a warning call, a stop call producing an error, variable assignment, and a print statement. Each produced the expected R output. An input field at the bottom reads 'Enter R code...' with a send button.

Uh-oh, these might be the droids you're looking for...

The number one request after every webRios demo was Android support. Early stage, but we have a working R console inside a native Android view.

Pure curiosity, not using the built-in mail client?

Send the logs to:

james.lastname@gmail.com

where last name is the display name here

More -> Settings -> Send Feedback

View inside of send feedback with “Send via Email” that auto attaches and formats error logs.

If you could go: More -> Settings -> Send Feedback. There’s an option to email with logs attached.

To confirm: the maximum stack size is only related to the Editor mode? If you run the previous code in Console everything "works"? This lends more credence to a Swift UI Sync hiccup.

Again, sorry about the issues. I do appreciate the checks. One quick favor can you do like 1+1 in the console? Also, a message(“test”)? If you pause while tying do you also get auto suggestions?

Huh... This might be more on the Swift UI side then. Interesting. I'll add some more debugging abilities to try to isolate further in the next version. Very content that startup was golden.

When you enabled detailed logging, the app needs to be restarted before it kicks in. Was there anything in the startup log?

@tslumley.bsky.social The App Store just accepted v1.1.1. Could you try it out and let me know if you're still having issues?

View of available platforms filtered to iOS 17 that has simulator images available to install within Xcode.

Simulator iPad Pro 12.9 (2017) with iOS 17.0 running the code within webRios’ editor: r <- matrix(0, nrow=100, ncol=2) for(i in 1:100){ x <- rnorm(100) y <- rpois(100, 3) m <- glm(y ~ x, family=poisson) r[i,] <- coef(m) print(r[i,]) } plot(r) summary(r) Shows a series of output from executing commands.

Screenshot showing the new "Detailed Logging" along with "Send Feedback"

Okay, the last iOS simulator version I can obtain for Xcode is 17.5... Though, running the app on iPad Pro 12.9 (2017) using iOS 17.0 didn't trigger the error (see screenshots). So, what I've done is added a 'detailed debug' flag under Settings. I'm prepping an update over to App Store.

iPad Pro with iOS 26 running the code within webRios’ editor: r <- matrix(0, nrow=100, ncol=2) for(i in 1:100){ x <- rnorm(100) y <- rpois(100, 3) m <- glm(y ~ x, family=poisson) r[i,] <- coef(m) print(r[i,]) } plot(r) summary(r)

Argh. Back to the drawing board; thanks for trying… By the way are you on iOS 17/18? Again, I can run the MWE perfectly on production and my dev build.

Screenshot of webRios running on an iPad, showing a four-pane layout. The top-left Editor pane has an R script with code completion suggestions visible for the plot function. The bottom-left Console pane shows executed R output. The top-right Environment pane displays a variable x with a numeric value of 1. The bottom-right area shows Plots, Files, Packages, and Help tabs. A custom R keyboard row with operators like the assignment arrow, pipe, brackets, and common R symbols is visible at the bottom.

#webRios 1.1 is live! The big additions: code completion, customizable keyboard shortcuts, and a Data Import Wizard. Plus a better iPad four-pane layout (still a work in progress, more coming).

#RStats on your iPhone and iPad keeps getting better. Best experience on #iOS 26.

webRios was just updated to v1.1 in the App Store. If you have time, could you quickly try the app? I tried changed how some of the communication was occurring. I think that should solve the problem on earlier iOS version.

App Store Connect screenshot showing the webRios app with version 1.1.0 in "Waiting for Review" status.

webRios v1.1 is in the queue. Soon. #rstats #webR #iOS #AppUpdate

Screenshot of a Pyodide enabled Python Notebook mode on an iPhone App. A code cell with 'import this' sits above a Markdown cell currently being edited with the text 'Hello!' typed in. The Markdown cell is selected with a blue border and shows reorder, add, and delete controls. Below the cells is an 'Add Cell' button. he toolbar at top shows Run All, Code, Markdown, and Clear Outputs buttons. A bottom tab bar displays Console, Editor, Plots, and More options.

Screenshot of Pyodide enabled Python Notebook mode on an iPhone App. A code cell containing 'import this' has been executed, showing the output 'The Zen of Python, by Tim Peters' followed by its aphorisms: 'Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex.'

"import this" hits different when you're running it from your phone.

notebook mode. coming soon.

Screenshot of webRios showing autocomplete for the data.frame() functionc all in console mode.

Screenshot of webRios showing autocomplete for possible function names under the base R package.

Screenshot of webRios showing autocomplete for variable names inside of a data frame.

In the next build to hit the App Store, I've added better inline autocomplete.

So, I think I have a fix for this in the next build that should be going to the App Store soon (tm).

On a similar note, we now have dynamic width set depending on: 1. text size, 2. layout mode, & 3. console vs. editor.

Screenshot of webRios running on an iPhone showing the revised editor interface with new blue run button for running a selection of R Code. The screenshot shows line highlighting and line numbers present.

Screenshot of webRios running on an iPhone showing the revised editor interface with green run button for running the entire R script as nothing is selected. The screenshot shows code folding being enabled without either line highlighting or line numbers present.

In the next build, I've wired the run button to switch between "green" for a full R Script run or "blue" when a portion of the R code is selected. Line numbers and highlight are now toggle in settings.
