Insights

AI Infrastructure Analyst

CoreWeave rapidly integrates Weights & Biases acquisition with three new AI development products, strengthening its end-to-end AI infrastructure capabilities.

CoreWeave has announced three new AI cloud software products that represent the first integration between CoreWeave's infrastructure and Weights & Biases following their May 2025 acquisition. This rapid integration—completed in just six weeks—demonstrates impressive execution speed and strategic focus on enhancing their AI development ecosystem.

The new offerings address critical pain points across the AI development lifecycle:

• Mission Control Integration connects infrastructure monitoring with model training, allowing developers to correlate hardware events with training runs—a significant capability for debugging complex distributed training jobs
• W&B Inference provides simplified access to leading open-source models including DeepSeek R1-0528 and LLaMA 4 variants through CoreWeave's infrastructure
• W&B Weave Online Evaluations enables continuous monitoring of production AI systems across cloud platforms

This product launch represents a strategic evolution for CoreWeave from primarily offering specialized GPU compute to providing higher-level AI development tools. By vertically integrating infrastructure with developer tooling, CoreWeave is positioning itself as a comprehensive AI platform rather than just a specialized infrastructure provider. This approach could potentially increase customer stickiness, expand their addressable market, and improve margins through higher-value services.

While these products are currently in preview, their development signals CoreWeave's ambition to capture more of the AI value chain and compete more directly with comprehensive cloud providers. The integration of observability from hardware to application layer ('metal-to-token') creates a differentiated offering in the market where most providers excel at either infrastructure or development tools, but rarely both.

LIVINGSTON, N.J., June 18, 2025 /PRNewswire/ -- CoreWeave (Nasdaq: CRWV), the AI Hyperscaler™, announced today at the Weights & Biases Fully Connected Conference, the launch of three new AI cloud software products and capabilities to help customers develop, deploy, and iterate AI faster. Today's rollout is the first software integration leveraging CoreWeave's cloud services to power Weights & Biases, the AI developer platform, following CoreWeave's acquisition of Weights & Biases in May 2025. The new products and capabilities provide leading AI labs, AI engineers, and AI developers a robust AI platform to train models, perform inference at scale and efficiently, and monitor production AI applications.

New products and capabilities announced today include:

• Mission Control Integration: CoreWeave's Mission Control, a groundbreaking cluster health management system, is now available through W&B Models – boosting productivity and improving efficiency by enabling AI engineers and ML researchers to correlate infrastructure events directly with training runs, simplifying diagnostics for issues like node failures, hardware errors, and networking timeouts. Now AI engineers and ML researchers can gain real-time insights and remediation tips enabling rapid identification and resolution of training disruptions.
• W&B Inference: Powered by the CoreWeave Cloud Platform, W&B Inference gives AI developers a simple way to access and explore leading open-source AI models through a single interface including DeepSeek R1-0528, LLaMA 4 Scout 17Bx16E, and Phi 4 Mini 3.8B.
• W&B Weave Online Evaluations: Gives W&B Weave AI developers real-time insights into how their AI agents are performing in production on any cloud platform, so they can quickly detect and resolve issues, make continuous improvements with new evaluation datasets, and ensure quality over time.

"Today's announcement demonstrates how CoreWeave and Weights & Biases together can accelerate and enable our customers to unleash the potential of AI," said Chen Goldberg, Senior Vice President of Engineering at CoreWeave. "After just six weeks, we are thrilled to launch these capabilities which support rapid AI innovation and enable more developers to build on the CoreWeave Cloud Platform."

"When we joined the CoreWeave team, we were excited to build tools that further the next generation of AI breakthroughs by integrating our existing cutting-edge training and evaluation developer tools with CoreWeave's high-performance cloud infrastructure," said Lukas Biewald, GM of Weights & Biases. "In this first joint launch, we have delivered for our customers with metal-to-token observability and inference integrated with application level observability."

With these new integrated platform capabilities, CoreWeave and Weights & Biases are setting a new standard for performance, transparency, and efficiency in AI development. By combining powerful infrastructure with intuitive tooling, the unified platform empowers AI engineers, AI developers, and ML researchers to iterate faster, scale seamlessly, and push the boundaries of what AI can achieve. Today's launch underscores CoreWeave's continued commitment to supporting the world's most advanced AI innovators.

Mission Control Integration, W&B Inference and W&B Weave Online Evaluations are currently available to customers in preview.
