Changelog

What’s new in Prediction Lab.

June 26, 2026

Computed Columns & Multi-File Geographies

Features

  • Build new columns from the ones you already have. Define a column as an expression over existing columns, using add, subtract, multiply, or divide. It then behaves like any other column: profiled with summary statistics and correlations, and ready to use as a feature, target, or filter. Division guards against a zero divisor by returning an empty value, so ratio metrics like claim count over earned exposure are safe to build. A structured editor previews each row as you go.
  • Create one geography from many files. Select a whole set of boundary files at once, such as 50 per-state shapefiles, and they're combined into a single geography on upload with no external GIS step first. Uploads run in parallel with combined progress, and single-file uploads work exactly as before.
  • Deletions now show up in the activity feed, so a removed dataset, model, or geography leaves a visible trace.

Improvements

  • Large, dense maps now render at every zoom level. Geographies with hundreds of thousands of areas, like Texas census blocks, used to come up blank when zoomed out. Areas now merge as you zoom so the map stays readable at any level.
  • Distribution chart series are now colored individually, while the bars stay neutral.
  • Better keyboard navigation, control labeling, and screen-reader support throughout the app.
  • A range of modeling, mapping, and data-processing operations run faster on large datasets.

Fixes

  • A Tweedie model's power setting no longer reverts to its default when you reload the model.
  • The AI assistant no longer drops characters mid-response when connected to a local model.
  • Restored support-chat message delivery.
  • Fixed a crash on the model page caused by automatically built features.
  • Gamma and Inverse-Gaussian fits now reject non-positive responses instead of failing silently.

Guided Onboarding & Distribution Tables

Features

  • A guided welcome the first time you open the app. New installs now open with a short product tour through Datasets, Models, and Reviews, followed by a chooser for how you want to connect: this computer, a cloud organization, or your own EC2 server. You can replay it anytime with the "Restart onboarding" command.

Improvements

  • Read your distributions as exact numbers. Every column distribution now has a table view alongside the chart, with weight columns labeled per series and values formatted for easy reading. The chart and table both follow your active filters, partitions, and targets.
  • Distribution charts and their exports now carry the chart title and the filters you've applied, so a shared chart shows where its numbers came from.
  • Relative mode now reads directly on the response axis.
  • The app loads faster on startup.

Fixes

  • Weight distributions now fall back to row counts when a target has no weight column, so the chart renders correctly even without one.

June 15, 2026

Model Comparisons & Map Views

Features

  • Compare full model fits inside a review. Model reviews now show goodness-of-fit deltas, a coefficient-shift table, and a feature-importance diff between the two model versions, bringing them to the same depth as dataset reviews.
  • Build conditions by dragging them into place. Filter, partition, and custom factor dialogs let you reorder, regroup, and nest conditions by drag and drop.
  • You can now view a model's effects as a geographic map, painting the selected column as a choropleth across each partition.

Improvements

  • Editing on a protected branch now creates the branch inline from the same dialog, keeping you in one flow.
  • Column distribution maps now include a Total panel alongside the per-partition panels.

Fixes

  • The activity feed now refreshes after dataset edits and version transitions.
  • Review change diffs show real object names, and the review detail page scrolls cleanly, shows breadcrumbs, and falls back gracefully when an author name is missing.
  • Model-effect charts no longer get stuck loading when every effect is selected.
  • Model configuration is locked while an automated feature build is running, preventing conflicting edits.
  • Fixed MCP Server installation on signed macOS builds.
  • Fixed a geography ingestion failure that occurred when the canonical file was missing.

June 10, 2026

Dataset Review Diffs & AI Modeling Agents

Features

  • Dataset reviews now show exactly what changed. Open a review to see a field-level diff of every column and value, with row, column, and size deltas summarized at the top. Expand a changed column for its full profile, including how its distribution and quantiles shifted and its most common values. You can preview a merge before approving it and rebase a review when its base version moves, and a pure column rename is now recognized as a rename rather than a column dropped and re-added.
  • AI agents can run the full modeling workflow. A connected agent can move through the whole pipeline: exploring your datasets, ingesting files and geographies, setting filters and partitions, and fitting models, then reading the results back without writing raw queries.
  • Distributions render as maps in more places. Column distributions now stay on a choropleth map even with partitions or targets enabled: partitions become a scrollable grid of maps, and targets switch between weight and response. The correlation page gains the same map view, each with a color-scale legend.

Improvements

  • The activity feed now covers deletes, renames, and changes to nested items, each written as a specific, readable message.
  • Live updates recover after a dropped connection and catch up on anything they missed, so changes from your team stay in sync.
  • Model-fit notifications name the model and partition slice they finished.

Fixes

  • Dataset and geography rows that showed Ready no longer error with "no version yet" when opened.
  • You can delete a workspace after removing its last dataset.
  • Fixed a crash on the model page right after creating a branch.
  • Canceling the create-branch dialog no longer leaves a feature stuck on and locked.
  • A processing dataset no longer shows up in the wrong workspace or as a duplicate row.
  • The Fit button re-enables after you change a feature or filter, so you can refit.
  • Custom-factor conditions populated from a distribution no longer hang on "Loading…".
  • ⌘K opens the page Actions menu even when your cursor isn't in a text field.
  • A newly created model appears on the dataset page right away.
  • Branch names can now contain spaces.

Status Page Polish

June 2, 2026

Public Status Page & Reliability Fixes

Features

  • You can check Prediction Lab's live status anytime. A new public status page at status.predictionlab.ai shows current and historical uptime for the website and the services the app runs on.

Fixes

  • The map now renders its base layer in the installed app, which could previously appear blank.
  • The in-app changelog now shows the notes for the version you're actually running.
  • Disabled items in right-click menus now show a tooltip explaining why they're unavailable.
  • Smoothed out brief API hiccups that could occur while a new version was being deployed.

Connect to AI, Model Import, & Lorenz Curves

Features

  • Your AI assistant can now do anything you can do in the app. Once it's connected to your workspace, it works directly with your real data and models, building, exploring, and analyzing right alongside you. Turn it on from the new MCP Server page in settings: install the connector and paste in the config it generates.
  • Move models in and out of Prediction Lab. Export any model to a portable file to hand off or archive, and import models back in, including exports from legacy software.
  • See how well your models separate outcomes. A new Lorenz Curve view shows how sharply each fit discriminates, with a Gini score that sums it up in a single number you can compare across fits.
  • Feature Importance. A new page ranks your rating factors by how much each one drives the model's predictions, so the biggest contributors stand out immediately.
  • Replace a dataset's file in place. Swap in an updated file for an existing dataset without recreating it from scratch.

Improvements

  • Distribution expressions are now structured and validated. Building a distribution dimension is more guided, and errors are caught early with a clear message.
  • Long-running operations now report their progress in plain terms, like "Building tree 45/100."
  • Pages with mathematical notation load noticeably faster.

Fixes

  • Lift charts now bin consistently when filters are applied, so the curve no longer shifts as you slice the data.
  • The map attribution panel starts collapsed, giving the map more room.
  • Removing an unreachable saved cloud connection from the welcome screen now works, and a stale active-organization selection recovers on its own.
  • Starting a support chat no longer leaves a half-created conversation behind if something fails partway through.
