W&B Models performance
Fast logging, immediate results
Building foundation models is incredibly resource-intensive, requiring vast amounts of data, substantial processing power, and millions of iterations. Weights & Biases delivers the performance and scalability the world’s leading AI foundation model builders demand.


Scalable performance
As the size of models grows larger, the systems required to build these models must grow larger to keep pace. The W&B SDK handles logging and organizing tens of thousands of data points in parallel with near-linear scalable performance allowing ML engineers and data scientists to analyze thousands of runs simultaneously.
Low logging overhead
Tracking an experiment should never delay or disrupt executing the experiment itself. The W&B SDK consumes only the resources required and nothing more, speeding up your runs and reducing costs.
Reliability
Protect your progress and avoid data loss and delays caused by unexpected failures. W&B Models offers seamless recovery from failed runs, keeping your projects on track.
Quick & responsive interface
When comparing thousands of runs across thousands of steps, it’s disruptive waiting for data to load. W&B Workspace delivers all interactive charts and tables immediately, no matter the run count or size, in customizable sections and panels.
