exametrika vs Windmill: at a glance
What is exametrika?
A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.
exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.
What is Windmill?
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
Two lines are moving at once. The platform line made dbt projects a first-class runtime, unified the deployment target on workspace lineage, opened Compare & Deploy to arbitrary target workspaces, and moved BigQuery and Snowflake out from behind the Enterprise license. The AI line took sessions to beta on by default and has been adding controls around them since — file attachments, visible web-search sources, artifact version history, and now a read-only plan mode that refuses anything that writes or deploys until you approve a plan.

exametrika
0.0INFRA · APIS
A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.
◆ Current state
exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.
◆ Where it's heading
The arc runs from feature sprawl to consolidation. Through 1.9.0-1.13.0 the package added polytomous biclustering plots, nominal and ordinal IRM samplers, a C++ Gibbs core, and Graphical Lasso; the cost was inconsistent interfaces and correctness bugs that only surfaced under audit. The maintainer is also visibly optimizing for two external gatekeepers — CRAN's 10-minute check budget in 1.13.1, an R Journal reviewer in 1.14.0 — which suggests the package is being groomed for formal publication rather than just iterated on.
◆ Prediction
Expect the next release to continue the deprecation cleanup started in 1.15.0, likely retiring some of the old function names that have carried warnings since 1.7.0, with new modelling work paused until the R Journal submission clears.
Windmill
8.8INFRA · APIS
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
◆ Current state
Two lines are moving at once. The platform line made dbt projects a first-class runtime, unified the deployment target on workspace lineage, opened Compare & Deploy to arbitrary target workspaces, and moved BigQuery and Snowflake out from behind the Enterprise license. The AI line took sessions to beta on by default and has been adding controls around them since — file attachments, visible web-search sources, artifact version history, and now a read-only plan mode that refuses anything that writes or deploys until you approve a plan.
◆ Where it's heading
Windmill is positioning as the place a data team's existing work already runs rather than a system to be ported to: an unmodified dbt project drops in, its models become addressable assets with ref() lineage, and the warehouse languages needed to reach them are no longer paywalled. In parallel, the AI session work is maturing from capability to governance — the recent additions are all about reviewability and constraint, not raw autonomy. The deployment changes point the same way, collapsing configurable targets into a single derived answer.
◆ Prediction
Expect the plan-and-approve posture to spread beyond session chats into the durable AI surfaces, and more warehouse-adjacent runtimes to follow dbt into the first-class treatment; Oracle and MS SQL remain the obvious Enterprise holdouts to watch.
