fastml vs nert: at a glance
What is fastml?
fastml added survival modelling and leakage-proof resampling, moving past classification and regression.
A tidymodels-based AutoML wrapper that trains, tunes and compares many engines from one call. The 0.6.x line added engine-specific tuning parameters, class-imbalance handling, early stopping and DALEX-based explainability. The 0.7.5 release is far larger: a full survival analysis task with its own engines, MICE imputation and integrated Brier scoring, plus unbiased nested cross-validation, grouped, blocked and rolling resampling helpers, fold-wise imputation, recipe leakage checks, and a sandbox for user-supplied preprocessing.
What is nert?
nert put fourteen TERN datasets behind one dispatcher and called it stable.
nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.

◆ Current state
A tidymodels-based AutoML wrapper that trains, tunes and compares many engines from one call. The 0.6.x line added engine-specific tuning parameters, class-imbalance handling, early stopping and DALEX-based explainability. The 0.7.5 release is far larger: a full survival analysis task with its own engines, MICE imputation and integrated Brier scoring, plus unbiased nested cross-validation, grouped, blocked and rolling resampling helpers, fold-wise imputation, recipe leakage checks, and a sandbox for user-supplied preprocessing.
◆ Where it's heading
The package is moving from convenience wrapper to something that has to be defensible statistically. Nested cross-validation, fold-wise rather than up-front imputation, and explicit leakage checks are all corrections to the shortcuts that make AutoML easy and its scores optimistic. Survival adds a third task type alongside classification and regression, and it arrived with its own metrics rather than being bolted onto the existing ones. Note the entry body is cut off at 8,000 characters, so the release is larger than what is shown.
◆ Prediction
Expect the remaining survival engines to fill in and the sandboxing of custom preprocessing to tighten, since both were still being iterated on within this same release's commit list.
nert
0.0ANALYTICS
nert put fourteen TERN datasets behind one dispatcher and called it stable.
◆ Current state
nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.
◆ Where it's heading
The release history is unusual in that most of its tags are not releases: Milestone 1, 2 and 4 were pushed within eight minutes of each other in July 2025 purely as grant reporting and audit markers, with no user-facing content. What the 1.0.0 notes emphasise instead is test discipline — 310 deterministic offline tests, snapshot pins on every TERN bucket path and filename template, and mocked COG reads so R CMD check never touches the network. That is a client built on the assumption that the remote API's URL structure will change underneath it.
◆ Prediction
The notes describe pre-CRAN review polish and itemise remaining check NOTEs in cran-comments.md, so the next move is most likely a CRAN submission rather than additional dataset coverage.
