rsample vs Writer
A side-by-side editorial comparison of rsample and Writer — release velocity, themes, recent moves, and the top alternatives to consider.
rsample vs Writer: at a glance
What is rsample?
tidymodels' resampling package is retiring its old splitters for sliding windows.
rsample is at 1.3.2, a small release covering spatialsample interoperability and a soft deprecation of the lag argument on initial_time_split(). The more consequential work sits behind it: 1.3.1 added internal_calibration_split() and a calibration() accessor so tune can fit a preprocessor and a post-processor on separate parts of the analysis set, and 1.3.0 superseded rolling_origin() with the sliding_* family.
What is Writer?
Writer sells the agentic marketing org first and the platform second.
This feed carries Writer's blog and webinar stream rather than a release log. The six recent items are executive-audience content — a Vanguard CMO interview, a Forrester analyst session, a Beauty Pie customer story, a capacity-crisis argument aimed at wealth management — alongside two pieces on AI visibility for enterprise marketers. Product news is rare in the stream; the most recent example visible is a July post on upgraded Playbooks with modular steps, built-in testing and bulk runs.

tidymodels' resampling package is retiring its old splitters for sliding windows.
◆ Current state
rsample is at 1.3.2, a small release covering spatialsample interoperability and a soft deprecation of the lag argument on initial_time_split(). The more consequential work sits behind it: 1.3.1 added internal_calibration_split() and a calibration() accessor so tune can fit a preprocessor and a post-processor on separate parts of the analysis set, and 1.3.0 superseded rolling_origin() with the sliding_* family.
◆ Where it's heading
Two threads run through the window. Time-based resampling is migrating from rolling_origin() to sliding_window(), sliding_index() and sliding_period(), while validation_split() and its relatives have moved from soft deprecation to warning in favour of the three-way initial_validation_split(). Alongside that, rsample is growing infrastructure other tidymodels packages consume rather than user-facing splitters.
◆ Prediction
Given that validation_split() and friends now warn and initial_time_split()'s lag argument is soft-deprecated, the next release most likely escalates those deprecations rather than adding a resampling scheme.
Writer
5.0AI-ASSISTANTS
Writer sells the agentic marketing org first and the platform second.
◆ Current state
This feed carries Writer's blog and webinar stream rather than a release log. The six recent items are executive-audience content — a Vanguard CMO interview, a Forrester analyst session, a Beauty Pie customer story, a capacity-crisis argument aimed at wealth management — alongside two pieces on AI visibility for enterprise marketers. Product news is rare in the stream; the most recent example visible is a July post on upgraded Playbooks with modular steps, built-in testing and bulk runs.
◆ Where it's heading
The content is organized around a single argument: marketing organizations should be restructured around agents, with some functions owned by software rather than people. Writer is making that case through named executives and analysts rather than practitioner how-tos, which is content built for buying committees. A second track is forming around AI visibility — how brands get surfaced and cited by AI systems, framed as the discipline that follows SEO.
◆ Prediction
Expect more named-executive and analyst sessions on the same agentic-org thesis, with AI visibility growing as the second theme. Product changes will keep reaching this feed sporadically, so releases like the Playbooks update will be hard to spot or date from here.
