## What the story says

Personal AI uses W&B Artifacts to track datasets, view training results, and version and deploy the many individual personal language models it trains for its users. It also relies on W&B as a shared system of record and model hub for its production training and deployment pipeline.

Summary written by usedby from the source page, in English. The figures are those of Weights & Biases and Personal AI, not ours.

> With W&B Artifacts, we completely changed how we interacted with our user’s models. The platform provided an all-in-one solution to track datasets, view training results, and versioning and deploying models.

- **125 million**: “each with around 125 million parameters”

> I’ve worked with and trained models for over 15 years, and I have never encountered a platform as simple and intuitive as W&B
