modeltime.resample vs OpenCTI
A side-by-side editorial comparison of modeltime.resample and OpenCTI — release velocity, themes, recent moves, and the top alternatives to consider.
modeltime.resample vs OpenCTI: at a glance
What is modeltime.resample?
modeltime.resample exists to keep backtesting working as tidymodels shifts underneath it.
modeltime.resample runs time series cross-validation over modeltime models, returning per-resample predictions and accuracy plots. Version 0.3.0 is the substantive release in view: tune 2.0.0 compatibility, deterministic seeding via withr, guaranteed .predictions output, and clearer failures when resample fits break. The three releases before it are dependency chores.
What is OpenCTI?
OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
The mainline is working through the consequences of the connector catalog redesign, with each release closing gaps around it: filters and saved searches became shareable, dashboards can reuse them, and background tasks can now edit relationship start and stop times in bulk. Alongside that, an LTS branch is being maintained in parallel — 7.260309.0-lts.7 backports the security fixes and dependency updates from the recent mainline releases without any of the feature work.

modeltime.resample exists to keep backtesting working as tidymodels shifts underneath it.
◆ Current state
modeltime.resample runs time series cross-validation over modeltime models, returning per-resample predictions and accuracy plots. Version 0.3.0 is the substantive release in view: tune 2.0.0 compatibility, deterministic seeding via withr, guaranteed .predictions output, and clearer failures when resample fits break. The three releases before it are dependency chores.
◆ Where it's heading
Every entry here is compatibility work against something upstream — hardhat 1.0.0, workflows regression mode, then tune 2.0.0 twice. The 0.3.0 notes show a second concern emerging alongside it: making failures legible, with .notes on failed fits, actionable errors from unnest_modeltime_resamples(), and fallback logic when prediction columns go missing across versions. Reproducibility gets the same treatment through explicit seeding.
◆ Prediction
Expect the next release to track the next tidymodels breaking change, with any new work continuing on error reporting rather than resampling strategies.

OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
◆ Current state
The mainline is working through the consequences of the connector catalog redesign, with each release closing gaps around it: filters and saved searches became shareable, dashboards can reuse them, and background tasks can now edit relationship start and stop times in bulk. Alongside that, an LTS branch is being maintained in parallel — 7.260309.0-lts.7 backports the security fixes and dependency updates from the recent mainline releases without any of the feature work.
◆ Where it's heading
Two things are running at once. The product arc is about making the platform's own surfaces composable — a faceted connector marketplace, reusable filters, workflow approval and draft metadata — rather than adding threat-intel primitives. The engineering arc is a maintained LTS channel that gets security parity and nothing else, which is how a project behaves once it has deployments it cannot ask to track weekly releases.
◆ Prediction
Expect the mainline to keep landing XTM Hub integration and workflow-governance work at roughly a weekly cadence, with a matching lts.8 backport following whenever the next batch of security fixes accumulates.
