mice vs Nextflow: at a glance
What is mice?
mice can finally predict, not just estimate, from multiply imputed data.
mice is the reference implementation of multiple imputation by chained equations, and the default answer to missing data in R. The releases here follow a consistent shape: one or two substantive additions per version, most contributed by outside authors, plus fixes to methods that have been in the package for years. The current 3.19.0 adds predict_mi(), which pools predictions across imputations under Rubin's rules and can return prediction intervals.
What is Nextflow?
Nextflow just made AI agents a task type, alongside processes and containers.
Nextflow ships on two tracks — dated edge releases carrying new work and 25.10.x/26.04.x stable lines taking backports — and the split is visible in every window: the edge builds run to dozens of commits while the stable patches are often plugin bumps alone. The current edge, 26.08.0-edge, introduces an agent primitive that makes AI agents first-class tasks, on top of steady work hardening the v2 config parser and type system. Cloud-executor plumbing, particularly for Seqera's own scheduler, is the other constant.

mice can finally predict, not just estimate, from multiply imputed data.
◆ Current state
mice is the reference implementation of multiple imputation by chained equations, and the default answer to missing data in R. The releases here follow a consistent shape: one or two substantive additions per version, most contributed by outside authors, plus fixes to methods that have been in the package for years. The current 3.19.0 adds predict_mi(), which pools predictions across imputations under Rubin's rules and can return prediction intervals.
◆ Where it's heading
Two things are happening. The imputation method catalogue keeps widening — lasso variants, multivariate PMM, categorical PMM via canonical correlation — while the pooling side is being extended past its original purpose, first to synthetic data, now to predictions on held-out sets. That second thread points at predictive modelling workflows rather than the inferential ones mice was built for. Meanwhile the maintainers keep finding consequential old bugs: the augment() ordered-factor defect in 3.18.0 had been silently degrading ordinal imputations for years.
◆ Prediction
predict_mi() is framed around evaluating predictive performance on test sets, and the ignore argument added in 3.12.0 already exists to hold out rows from the imputation model. Expect the next work to join those up into a fuller train/test story for imputed data, since the pieces are now in place but not yet connected.
Nextflow
6.3INFRA · APIS
Nextflow just made AI agents a task type, alongside processes and containers.
◆ Current state
Nextflow ships on two tracks — dated edge releases carrying new work and 25.10.x/26.04.x stable lines taking backports — and the split is visible in every window: the edge builds run to dozens of commits while the stable patches are often plugin bumps alone. The current edge, 26.08.0-edge, introduces an agent primitive that makes AI agents first-class tasks, on top of steady work hardening the v2 config parser and type system. Cloud-executor plumbing, particularly for Seqera's own scheduler, is the other constant.
◆ Where it's heading
Two arcs run in parallel. One is language maturity: the v2 parser, record types, typed outputs and the formatter have absorbed fix after fix across every release here, which is what a language does before it declares a syntax stable. The other is consolidation around Seqera — nf-tower folded into nf-seqera at 1.0.0, scheduler run identifiers propagate to Platform, and per-user CPU caps and secret references now cross that boundary. The agent primitive is the newest and least settled direction, arriving in edge rather than a stable line.
◆ Prediction
The agent primitive lands in an edge build, so the near-term question is whether it survives into a stable line unchanged or is reshaped first; the 26.04.x and 25.10.x branches show no sign of it yet. Expect the next edge releases to iterate on its interface while the stable branches continue taking parser and executor backports.
