What's New in Weights & Biases

26.16

July 13, 2026

ARIA gets a major upgrade with Agent Context: it automatically detects which project you're viewing in the app, so answers come with the right project already in mind. Open any project or run and start a conversation with ARIA to try it. What’s New - Agent chat keeps your sent message and ARIA’s response visible even if a background refresh happens while you’re waiting for a reply. - Agent chat renders Markdown tables, so structured data in ARIA’s responses displays as an actual table instead of raw text. - Agent chat renders more Markdown formatting, including headings, bulleted and numbered lists, inline code, and italics, making responses easier on the eyes. - Tool calls in agent chat expand to show their arguments and output, with formatting for commands, diffs, and JSON. Errored and cancelled tool calls display their status, and clarifying questions render as a question prompt with selectable options. Bug Fixes - Text field placeholders display in the correct color.

Good

I am surprised wandb even having apps, very convenient for me!

Incredible, but not complete

It’s amazing to now have an official Weights and Biases app. This has been very helpful to me.
However it is missing some key features regarding the graphs like setting smoothing settings, picking which runs to show to compare between, and other stuff like that.
But overall it is incredible.

Needs more features

Love the ability to see experiment results on the go, but I’d like to be able to group and tag runs similar to how the web version works.

Poor filtering

I’m very happy that there’s an app now, but I wish there was better filtering so I could compare runs

Years late and artificially limited

This app only works if you have a paid multi-tenant W&B account. If you’re on an individual or free plan, you’re locked out, and nothing in the App Store listing tells you that before you download. The community has been asking for mobile access for years, and gating it behind enterprise pricing is a bizarre choice. Worth noting: as of 22 March 2026, individual runs are actually visible in the app, which makes the restriction feel more like a deliberate product decision than a technical limitation. 2 stars from 1 since it partially works in its current state

If you're encountering issues logging in or seeing your runs, please send a note to support@wandb.com and we're happy to dig into the problems you're seeing. Thanks again.
