W&B v0.76 delivers a major boost to experiment insight and productivity, introducing smarter media tools, smoother workflows, and powerful new interfaces. Multi-video sync with autoplay and looping enables quick, side-by-side evaluation, while simplified workspace navigation keeps you moving effortlessly between views. Plus, the new LEET terminal UI brings fast, real-time run insights directly to your command line.
Support and end of life
- W&B Server v0.63 and below reached end of life on November 20, 2025.
- W&B Server v0.65 is scheduled to reach end of life on January 30, 2026.
Features
-
Multi-video Sync: Play and control multiple video panels together for qualitative evaluation and comparison of training runs, analysis of model behavior across experiments, and evaluation of multimodal model checkpoints.
With synchronized video playback, you can play, pause, scrub, and adjust the speed of multiple videos in sync, enabling true side-by-side comparison for quick visual QA to evaluate style, timing, motion, and more.
To try it, go to Settings → Media. Currently available in Dedicated Cloud only.
-
Autoplay and loop media in video panels in a workspace or section. Currently available in Dedicated Cloud only.
-
Now in Dedicated Cloud, updates to workspace navigation simplify moving between multi-run and single-run workspaces and ensuring view changes are saved between both (quick demo video).
- Single-run and multi-run saved views now use shared configuration details to reduce repetitive setup tasks.
- Existing single-run saved views are removed, and you will need to recreate the ones you still need.
These updates are expected in W&B Self-Managed in January 2026.
-
You can now copy a run’s name or path from the run selector menu. This update also fixed a bug where a copied run name would include the run name twice.
-
W&B Lightweight Experiment Exploration Tool (LEET) (Beta) is a fast terminal UI for observing your ML training runs, including stats, metrics, and system health. It reads and visualizes live log files to provide a fast, customizable, browser-free experience in real time.
LEET presents an interactive, three-pane dashboard that updates live as your run progresses.

Fixes
- Min and max values now display on grouped line charts to help with comparisons.
- Reports now truncate long media panel titles for cleaner presentation.
- Semantic legends now allow editing the upper bounds of buckets.
- Fixed a bug when switching semantic colors from *iscrete to continuous values.
- Fixed a bug that could cause flickering when resizing charts in full-screen mode.
- Fixed a bug that could cause rendering issues when the y axis is set to
_step. - Fixed a bug that could prevent the media step slider from updating to show the latest incoming data if it is set to the maximum value.
- Fixed a bug where image smoothing settings were not always applied to image panels with smoothing turned on.
- Fixed a bug where media panels in grid view could take up too much vertical space, causing excessive scrolling.
- Fixed minor display issues when rendering and refreshing automations.
- Fixed minor UI bugs when linking artifacts, including scrolling and count rendering issues.
- Fixed a bug that could prevent non-ASCII characters from displaying in HTML table media panels.
- Updated the Edit run name action to make it more clear whether you are updating the run's display name for the workspace or the underlying run name across the project.
