Nebius has announced the release of Nebius AI Cloud 3.1, introducing the next-generation NVIDIA Blackwell Ultra compute and extended operational tools for its full-stack artificial intelligence (AI) cloud platform. Version 3.1 upgrades the existing Nebius AI Cloud “Aether” foundation by adding transparent capacity management and expanded infrastructure capabilities, aiming to address the requirements of organizations scaling AI workloads in production data center environments.
Nebius reports global deployment of NVIDIA Blackwell Ultra infrastructure, specifically highlighting NVIDIA GB300 NVL72 and NVIDIA HGX B300 systems now available for customer use. According to Nebius, it is the first cloud provider in Europe to operate both systems in production. The platform is also identified as the first globally to run production GB300 NVL72 systems on 800 Gbps NVIDIA Quantum-X800 InfiniBand, doubling throughput for distributed AI and machine learning workloads. Additional technical improvements include hardware-accelerated networking, expanded filesystem performance, and advanced storage write-back caching to remove infrastructure bottlenecks.
Operational upgrades in Nebius AI Cloud 3.1 include the introduction of Capacity Blocks and a real-time Capacity Dashboard, delivering total visibility into GPU resources across all data center regions. The update also adds project-level quotas and customizable object storage lifecycle rules, enhancing resource allocation precision and cost management.
For data center operators and technology vendors supporting developer-centric workflows, the update extends integration with Dstack for workflow orchestration, facilitates deployment of NVIDIA BioNeMo NIM microservices—including Boltz2, Evo-2, GenMol, and MolMIM—without requiring NVIDIA GPU Cloud (NGC) keys or separate NVIDIA AI Enterprise licenses. Platform enhancements also include advanced Slurm-based orchestration with Manager Soperator, FOCUS-compliant billing exports, and improved user interface elements.
Nebius AI Cloud 3.1 further strengthens security and governance for regulated environments by adding audit logs for object storage data-plane events (supporting Health Insurance Portability and Accountability Act compliance), per-object access controls, and Virtual Private Cloud (VPC) Security Groups. Improved identity and access management now supports Microsoft Entra ID integration and provides granular service roles for simplified, secure multi-tenant administration.
