Weights & Biases build state-of-the-art tools for machine learning. Use W&B for experiment tracking, whether you're launching a few runs on your laptop or thousands of distributed training jobs. They have extensive experience working with companies to turn ML research projects into scalable, real-world deployments. They were watched hundreds of teams struggle to deploy models successfully, and the same problems show up repeatedly. Machine learning has created a fundamentally new kind of programming, requiring a new set of developer tools. They created Weights & Biases to provide that missing toolkit. They are partnering with OpenAI, Toyota Research Institute, and others to develop a product that helps them build better models.
