Train, fine-tune, and manage AI models

W&B Models helps you train, fine-tune, govern, and manage models from experimentation to production, accelerating time to market. It boosts experiment speed and team collaboration to bring models to production faster while ensuring performance, data reliability, and security. Run more experiments, analyze them interactively, and quickly build higher-quality models. Centralize the tracking of models, datasets, metadata, and their lineage in the Registry to support governance, reproducibility, and CI/CD. Automate workflows for training, evaluation, and deployment to enable rapid iteration.

Accelerate experiment velocity

Track, version, and visualize experiments with just a few lines of code. Run hundreds of thousands of experiments faster and produce higher quality models more quickly. Easily visualize and analyze experiment results and uncover insights.

Manage models centrally

After training, you can publish and share models, datasets, and metadata in the Registry, creating a single source of truth for all your AI assets. This enables reproducibility, versioning, lineage tracking, and continuous integration/deployment (CI/CD).

Scale with performance

W&B Models is built to support large-scale and long-running experiments and extensive data logging. Run 100,000+ experiments with thousands of metrics and millions of data points at fast logging performance. Quickly upload and download large model files at frontier AI scale.

Improve governance and security

Use the Registry and lineage graphs to reproduce the exact recipe for a given model to improve collaboration and regulatory compliance. W&B Models provides enterprise security with endpoint protection, encryption, and backup controls. It offers fine-grained, role-based access through custom roles, teams, and projects, allowing secure data sharing with appropriate access levels. Your data is protected with robust encryption: TLS 1.2+ for in-transit and AES 256 for at-rest, ensuring security throughout the data lifecycle.

Extensive system metrics tracking

W&B Models offers pre-built integrations with hardware platforms like NVIDIA, tracking a full range of GPU/CPU system metrics out of the box. Using W&B Models, you can visualize this data side by side with other metrics to maximize GPU utilization and cut training costs. No hassle of setting up system metrics logging yourself.

Built-in integrations

Easily integrate with your existing ML development stack with no vendor or framework lock-in. With thousands of integrations for the most commonly used ML frameworks, libraries, and repos, the W&B SDK works with the tools your team uses every day.

Flexibility of deployment options

W&B Models gives you a choice of deployment options, including multi-tenant and dedicated cloud environments managed by us, as well as on-premises and private cloud environments that you manage independently.
