Every stage of the AI lifecycle depends on the ability to store and move massive volumes of data efficiently. Training, inference, checkpointing, data preparation, model outputs, and retrieval-augmented generation (RAG) all require storage that performs at the speed and scale modern AI demands. Without reliable storage infrastructure, even the world's most powerful compute resources sit idle. This strategic agreement between Backblaze and CoreWeave addresses this critical need by providing cost-efficient storage capacity that supports the massive data requirements of AI workloads at scale.
Under the multi-exabyte agreement, Backblaze will provide HDD-based storage tiers in CoreWeave AI Object Storage, helping optimize placement of data across performance tiers. This approach preserves high-performance storage resources for the most demanding AI workloads while leveraging cost-efficient storage for less frequently accessed data. CoreWeave's patented LOTA distributed cache ensures that customers can immediately access these new service tiers without any code modifications, providing seamless integration and immediate value.
Gleb Budman, co-founder and CEO of Backblaze, commented on the significance of the agreement: "Storage is the foundation every AI workflow is built on — without it, even the world's most powerful compute sits idle. We're pleased to work with CoreWeave on elements of their storage environment. This collaboration demonstrates how our platform can help organizations meet growing infrastructure demands."
CoreWeave's AI cloud platform spans infrastructure, technology, tools, and services.
