What's New in Weights & Biases

26.22

August 24, 2026

What’s New - Charts zoom and scale on both axes. Pinch vertically as well as horizontally, double-tap to zoom in a step at a time, and watch the Y axis rescale to the visible portion of the curve so small variations late in a run stay readable. - Run cards on the Runs tab prefer a project’s starred metrics when choosing which metric to display. - Viewing logs for a finished or crashed run stops polling for new lines, cutting network use and battery drain.

★★★★★ Finally, I can check on my runs without pulling out my laptop

As a researcher, I’m constantly checking on training runs, and until now that meant squinting at the mobile browser or waiting till I’m back at my desk. Having a real app that just shows me my metrics and lets me glance at loss curves while I’m grabbing coffee is honestly a game changer. So much smoother than the browser version. Love it ❤️

Very handy for monitoring runs when away from desk

This is a useful app. I use it to view my projects, runs and has an AI agent -ARIA that analyses my runs and suggests next experiments.

Why no log scale?

Love the idea of this app, but there’s no option to change the axis scaling. Makes the app almost unusable for monitoring training
