What is parsnip?

parsnip added a whole new regression type, then wired R models to JAX and PyTorch

The package is expanding what tidymodels can express. Version 1.5.0 introduced ordinal_reg() as a new model type with three engines and its own link parameters, and added xgboost and qrnn engines for quantile regression. Version 1.6.0 followed with a keras3 engine for four model types, reaching Keras v3's TensorFlow, JAX and PyTorch backends. Around those, releases have been tuning-parameter range adjustments and engine-specific fixes.

What is Writer?

The Palmyra X6 launch lands twice — once as a digest, once as a press release

WRITER's feed is mostly thought-leadership for marketing leaders, with product news arriving in a named monthly format. This window carries the August digest announcing Palmyra X6, a faster WRITER Agent and new AI Studio governance, followed a day later by the press release restating the same launch for a wider audience. Everything else in the window is CMO-audience content: a CIO buy-in guide, a brand-differentiation interview, an AI-visibility playbook.

parsnip added a whole new regression type, then wired R models to JAX and PyTorch

◆ Current state

The package is expanding what tidymodels can express. Version 1.5.0 introduced ordinal_reg() as a new model type with three engines and its own link parameters, and added xgboost and qrnn engines for quantile regression. Version 1.6.0 followed with a keras3 engine for four model types, reaching Keras v3's TensorFlow, JAX and PyTorch backends. Around those, releases have been tuning-parameter range adjustments and engine-specific fixes.

◆ Where it's heading

Growth is happening on two axes: new modelling tasks that previously had no unified interface, and new engines behind tasks that already did. Both push in the same direction - a modeller specifies the model once and swaps the computational backend underneath, which is the whole premise parsnip is built on. The defunct surv_reg() shows old spellings being retired as that surface settles.

◆ Prediction

Expect further engines behind ordinal_reg() and quantile regression now that both have a home, and continued retirement of deprecated function names. The keras3 engine's multi-backend design is the obvious candidate to spread to more model types.

The Palmyra X6 launch lands twice — once as a digest, once as a press release

◆ Current state

WRITER's feed is mostly thought-leadership for marketing leaders, with product news arriving in a named monthly format. This window carries the August digest announcing Palmyra X6, a faster WRITER Agent and new AI Studio governance, followed a day later by the press release restating the same launch for a wider audience. Everything else in the window is CMO-audience content: a CIO buy-in guide, a brand-differentiation interview, an AI-visibility playbook.

◆ Where it's heading

The argument WRITER is making has moved from capability to economics. Both the digest and the press release lead on cost of running agents at scale rather than on what the model can do, and the governance work in AI Studio continues the admin-control arc the April digest opened. Owning the model family is what makes that pitch available, and WRITER is now leaning on it.

◆ Prediction

The next product signal should be the September 'New at WRITER' digest, most likely extending AI Studio governance or agent runtime performance rather than introducing another model — X6 is too recent for a successor.
