What's New in Weights & Biases

26.19

August 5, 2026

Enhanced Run Logs Introducing an enhanced run logs viewer, rebuilt for large training runs. ANSI color output renders faithfully, so colored output from your scripts looks exactly as intended. Recent log output appears immediately even for runs with hundreds of thousands of lines, with the rest loading in the background. Find it in the Logs tab of any run.

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
