The company has acquired Weights & Biases, a widely used developer platform for machine learning and AI model training, in a deal valued at around $1.7 billion, according to The Information. The acquisition positions CoreWeave to offer an end-to-end solution for AI development, bridging its cloud infrastructure with tools that power some of the world’s leading AI models.
Key Points:
- CoreWeave is acquiring Weights & Biases for approximately $1.7 billion.
- The deal strengthens CoreWeave’s AI cloud offerings ahead of its IPO.
- Weights & Biases, used by OpenAI, Meta, and Nvidia, will continue to support multiple cloud providers.
- The acquisition is expected to close in the first half of 2025, pending regulatory approvals.
Founded in 2017, Weights & Biases has become a staple in machine learning operations (MLOps), serving more than 1,400 organizations, including OpenAI, Meta, and AstraZeneca. Its tools help AI engineers track experiments, fine-tune large models, and monitor deployments, making it a critical component of modern AI workflows.
By acquiring Weights & Biases, CoreWeave gains a software layer that complements its high-performance cloud infrastructure, which is built to support AI workloads at scale. The move could help CoreWeave diversify its customer base beyond hyperscale clients like Microsoft, Meta, and Nvidia, which rely on its cloud servers for AI training but could eventually build their own in-house compute capabilities.
CoreWeave CEO Michael Intrator described Weights & Biases as a “phenomenal platform” that will enhance the company’s ability to support AI developers. “Together, we will bring new innovations to market faster and help customers accelerate their AI roadmaps,” he said in the announcement.
For Weights & Biases, the acquisition provides an opportunity to scale faster while retaining its commitment to interoperability. CEO Lukas Biewald reassured customers that they will still be able to run workloads on their preferred cloud providers. “CoreWeave is 100% committed to maintaining the interoperability that Weights & Biases is known for,” Biewald said.
The acquisition comes as CoreWeave prepares for a highly anticipated IPO, with reports suggesting the company could seek a valuation north of $20 billion. CoreWeave generated $1.9 billion in revenue last year, largely driven by demand for cloud infrastructure to train AI models.
The transaction is expected to close in the first half of 2025, subject to regulatory approvals.
