Weights and Biases is a tool for monitoring AI training runs.

I don't see how you can say it has "pre-AI use" unless you are narrowly defining AI to be LLMs.

Weights & Biases goes way back to 2017, before deep learning was called "AI". It's used for all sorts of non-AI ML too. It may be used for lots of AI but it sees a ton of non-AI use too. It's definitely not my thing (I prefer MLFlow) but lots of people love it.
