CoreWeave, a cloud-based AI infrastructure company offering GPU cloud services to simplify AI and machine learning (ML) workloads, has deepened its foothold in the AI development space by reaching an agreement to acquire Weights & Biases.  

The acquisition, which is reported by The Information to be valued at $1.7 billion, strengthens CoreWeave’s position by integrating Weights & Biases’ suite of tools for experiment tracking, model optimization, and workflow automation. The transaction is subject to customary closing conditions, including regulatory approvals. It is expected to close in the first half of 2025.

CoreWeave’s key infrastructure components include optimized GPU clusters, high-speed interconnects, dynamic GPU applications, and vertical AI stack optimization. While CoreWeave is known for providing high-performance computing power for infrastructure and managed cloud services, AI development isn’t just about raw GPUs. It requires the right tools to manage and optimize ML models. That’s where Weights & Biases comes in. 

Weights & Biases is widely used by AI researchers and engineers to manage the entire ML lifecycle, from training and hyperparameter tuning to deployment and performance monitoring. By bringing these capabilities in-house, CoreWeave is aiming to position itself as a more comprehensive AI development environment. 

This strategic move underscores the growing influence of Weights & Biases. Founded in 2017 by Lukas Biewald, Chris Van Pelt, and Shawn Lewis, Weights & Biases was built to provide AI developers with essential tools for building and refining machine learning models. Since then, the company has grown significantly and now has more than 1400 customers, including OpenAI, Meta, NVIDIA, Snowflake, and AstraZeneca. 

“Weights & Biases has built a phenomenal platform to help organizations of any size and across a range of industries to build, deploy, and monitor AI training and inference applications,” said Michael Intrator, co-founder and CEO of CoreWeave.

According to CoreWeave, the acquisition will allow its customers to “get real-time model performance monitoring and robust orchestration”. This integration is expected to create a more efficient AI development workflow, enabling teams to optimize models and accelerate deployment.

Weights & Biases emphasizes that the acquisition will not disrupt its existing customers, who can continue to deploy their AI models wherever they want. There is no compulsion to use CoreWeave’s cloud, however, customers are encouraged to consider that option, according to the company. 

The CEOs of both companies emphasized their aligned vision and commitment to AI acceleration. “We have long admired CoreWeave. We have a shared alignment of vision and values, and we are obsessively focused on helping our customers get to market faster with our cutting-edge technology and services,” said Lukas Biewald, co-founder and CEO of Weights & Biases.

“Together with CoreWeave, we will bring this grit and passion for innovation to customers at an even greater scale, with the goal of rapidly accelerating adoption across the world’s leading AI labs and enterprises. We are extremely proud of what we have built at Weights & Biases, and we can’t wait to see what we can accomplish together.”

The Weights & Biases acquisition comes days after CoreWeave announced its plans to go public in what is expected to be one of the biggest IPOs in recent years. CoreWeave is expected to aim for $4 billion in funds raised through the IPO, which would value the company at around $35 billion.

Some industry experts have highlighted that CoreWeave’s plan to go public coincides with a downturn in semiconductor stocks, which could potentially impact investor sentiment. CoreWeave also faced a recent setback when Microsoft decided to drop some CoreWeave services. Additionally, with the acquisition, CoreWeave enters a competitive market and would go up against other full-stack AI cloud providers such as Google Cloud Vertex AI and AWS SageMaker. 

The acquisition of Weights & Biases will help overcome some of these challenges and bolster CoreWeave’s position in the AI infrastructure market. It’s a strategic move that not only strengthens the company’s MLOps capabilities but also makes its cloud platform more attractive to enterprises and diversifies CoreWeave’s value proposition.
