- 📦Weights & Biases updated to version 26.31Introducing In-Chat Panels
- Introducing in-chat panels! When ARIA shares a Weights & Biases panel, it appears as a native bar chart or run history line plot right in the conversation, drawn from your live run data.
What’s New
- Tap a run state change push notification to open the run it refers to.
- Image metric detail follows the new chart detail design, with matching title, spacing, and background.
- Turn on “Exclude outliers” in line plot settings to keep extreme values from stretching the chart’s scale.
- See how many plots override each line plot setting in the project and run settings sheet, and tap Clear to remove those overrides for that setting.
Bug Fixes
- The Weights & Biases logo on the splash and login screens uses the updated branding.
- The star button on image detail stays in place while the screen opens.
- Log scale charts label adjacent axis ticks in a consistent notation.
- Values smaller than 0.0001 display their full precision in the chart selection lollipop on log scale charts.… more - ✏️Weights & Biases: new screenshots4 screenshots (was 4) · IN

- 📦Weights & Biases updated to version 26.30iPhone Duo Support
- Introducing iPhone Duo support! Runs and panels appear side by side on the expanded display, and hiding or showing a run updates its charts immediately. ARIA shows a single new chat button and a sidebar toggle that looks and sits like one. Open any project on iPhone Duo to try it.
What’s New
- A redesigned metric chart detail view is cleaner and shows more information. It opens fullscreen from the metric card with a zoom transition, lists each line in a legend under the title, and uses evenly spaced axis ticks that stay in place when you zoom.
- Choose the x axis for a chart from the built-in axes or any numeric key your run logs, and search your keys with “Search X axis”.
- The app icon is blue instead of yellow, reflecting Weights & Biases as part of CoreWeave Forge.
Bug Fixes
- Runs tab loads faster for users who were seeing slow loading.
- Metrics keep loading as you scroll to the bottom of projects with many metrics, such as large_runs_demo.
- Run Overview shows your config parameters with their usual names, without SDK storage wrappers or internal metadata.
- ARIA chat history displays each thread’s title.
- Trigger lists load every page of triggers and show the correct starred state for each project.
- The line plot options sheet stays put when you pull down, instead of refreshing.… more - ✏️Weights & Biases: new screenshots4 screenshots (was 4) · AE

- 📦Weights & Biases updated to version 26.29What’s New

- Profile, run overview, and notification settings pages keep a comfortable maximum width in landscape on larger devices.

- The Runs list shows an empty state when a search returns no results.
- ARIA history titles show the mentioned run’s name instead of its internal ID.
- ARIA chat history and the composer omit the placeholder project name for conversations started without a project.
- Search fields keep the capitalization you type instead of capitalizing the first letter.

- View image metrics from several runs at once on a project’s Panels tab. Page through each run’s image tile, scrub across steps with the slider, and switch samples with the sample picker when a run logs more than one image per step. Tap a run’s tile to open that run’s image metric detail view.
- Logged image captions appear on the image metric detail screen and in the fullscreen image viewer, with a tap to expand long captions into a scrollable panel.
Bug Fixes

Review momentum

Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Weights & Biases
Your model trains for hours. You shouldn't have to be at your desk the whole time.
Weights & Biases for iOS puts your experiments in your pocket. Check on a run during a seminar, catch a diverging loss before you leave the lab, or find out why a run crashed without opening your laptop.
SEE WHAT'S HAPPENING
• Browse your projects and runs, with your starred and recent projects first
• Pan, zoom and scrub training curves to read exact values at any step
• Switch to log scale, choose your x-axis, and adjust each chart to fit
• Open the Overview tab for config, summary metrics, hardware and environment details
• Read live logs when a run does something unexpected
KNOW WHEN IT MATTERS
• Get a push notification when a run fails
• Set metric alerts, such as "notify me if validation loss increases by at least 10%"
• Tap a notification to go straight to the run
ACT ON IT
• Stop a run that's gone wrong from your phone, so you stop burning GPU hours
BUILT FOR HOW RESEARCHERS WORK
No dashboards to rebuild. Sign in with your existing W&B account, and the app shows the projects you already track. The charts you see on the web are the ones you see on your phone.
Whether you're fine-tuning an LLM, training a model from scratch, or racing a conference deadline, W&B mobile helps you spend less time checking and more time thinking.
Available for Free, Academic, Enterprise (SaaS) and Dedicated Cloud accounts. On-premises deployments are not yet supported.
