What is MachineShop?

A mature R modelling framework refining variable importance and resampling controls

MachineShop provides a unified interface over a wide set of R model packages, handling fitting, resampling, performance metrics and variable importance behind one API. Recent releases are narrow and mostly corrective: 3.9.2 removed dead documentation links and fixed a Java parameter in a BART example, 3.9.1 ensured global settings reach compute nodes when varimp() runs in parallel and patched XGBoost model compatibility. The last release with real surface change was 3.9.0, which added offset support to XGBModel and a pool argument to calibration() controlling whether calibration curves are computed on pooled predictions or averaged across resampling iterations.

What is Retool?

Retool is retiring standalone Assist while folding the same capability into the app builder.

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

A mature R modelling framework refining variable importance and resampling controls

◆ Current state

MachineShop provides a unified interface over a wide set of R model packages, handling fitting, resampling, performance metrics and variable importance behind one API. Recent releases are narrow and mostly corrective: 3.9.2 removed dead documentation links and fixed a Java parameter in a BART example, 3.9.1 ensured global settings reach compute nodes when varimp() runs in parallel and patched XGBoost model compatibility. The last release with real surface change was 3.9.0, which added offset support to XGBModel and a pool argument to calibration() controlling whether calibration curves are computed on pooled predictions or averaged across resampling iterations.

◆ Where it's heading

Development has concentrated on variable importance and resampling rather than on adding models. 3.8.0 restructured the VariableImportance class to record which method and metric produced it, with an update() method to migrate objects from earlier versions, and extended term-specific p-values to Cox, POLR and survival regression models. 3.7.0 added grouped and stratified resampling to the control objects. The pace has slowed markedly - four releases in the last two years against six in the two before - and the recent content is compatibility work against XGBoost, parsnip, ggplot2 and recipes.

◆ Prediction

Expect the deprecated calibration pooling behaviour to be removed in a future release as the notes state, with the intervening versions continuing to track upstream model package changes.

Retool is retiring standalone Assist while folding the same capability into the app builder.

◆ Current state

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

◆ Where it's heading

The agent is being consolidated into the app builder rather than offered as a separate assistant, and Assist's removal is the clearest statement of that. Alongside it, the controls an administrator needs before letting an agent touch production data are arriving in the same cadence — resource-level policies, token management, permission migrations. Retool is treating agent capability and agent governance as one shipping problem.

◆ Prediction

Access policies should extend past PostgreSQL to other resource types as they exit beta, and the app-building agent will likely gain review or approval steps of its own.
