W&B offers a suite of integrated products. W&B Models facilitates the building and management of AI models, while its Training capabilities allow for fine-tuning AI models on agentic tasks. For inference, users can serve hosted and fine-tuned AI models. W&B Weave is specifically designed for iterating, evaluating, and monitoring agents, enabling the development of complex agentic AI applications.
The platform's Registry acts as a central hub for Datasets, Models, Prompts, Code, and Metadata, ensuring version control and reproducibility. Core features include Reports, Automations, SDKs, and skills for agents, alongside secure deployment options such as SaaS, Dedicated, and Customer-managed solutions. This flexibility caters to diverse enterprise needs and compliance requirements.
Weights & Biases is trusted by leading AI teams globally. The platform is compliance-ready, certified under ISO/IEC 27001:2022, ISO/IEC 27017:2015, and ISO/IEC 27018:2019, and compliant with SOC 2 and HIPAA standards. It also assists customers in complying with NIST 800-53 and aligns with GDPR requirements.
Integration is a key strength, with W&B easily integrating into existing workflows. It supports popular ML frameworks and libraries including LangChain, LlamaIndex, PyTorch, Hugging Face Transformers, TensorFlow, Keras, Scikit-learn, and XGBoost. Getting started is often as simple as adding a line of code to import the necessary libraries and initialize a W&B run.
The platform also offers a mobile app for iOS, allowing users to monitor AI experiments and track training runs remotely. This accessibility, combined with its robust feature set and enterprise-grade compliance, makes Weights & Biases a powerful solution for AI development at scale.
