The platform captures a wide array of data throughout the ML lifecycle, including training metrics, loss curves, hardware utilization (GPU, memory), and media outputs like simulation videos. This provides a holistic view of each experiment without requiring manual setup from the user.
Weights & Biases is built to ensure that any experiment can be reproduced and audited. It automatically logs the Git repository and commit hash, script parameters, and the lineage of data and model artifacts, creating a clear chain of custody from input data to final model.
The platform features an 'Automations' system that uses webhooks to integrate with external tools like GitHub Actions. These automations can be triggered by events such as a model being tagged for testing, automatically kicking off evaluation pipelines, report generation, or deployment processes.
The platform provides 'Registries' as a central, organization-wide repository for curated models and datasets. These registries feature independent, granular access controls and protected aliases, allowing teams to manage the lifecycle of production-ready assets separately from experimental ones.
Teams can collaborate through customizable 'Workspaces' and automated 'Reports'. These tools allow users to create tailored views of experiment results, compare runs, and share findings in a clear, documented format, complete with charts, media, and text.
