Nebius AI Cloud releases platform update offering Blackwell GPU infrastructure with enhanced capacity management tools.

Nebius announced Nebius AI Cloud 3.1, bringing NVIDIA Blackwell Ultra compute and enhanced operational capabilities to its full-stack AI cloud platform. The release builds on the foundation of Nebius AI Cloud "Aether" and addresses key operational priorities that customers face as they scale AI in production, including real-time visibility into GPU capacity across regions, transparent resource allocation for multi-team environments, and access to next-generation compute as models grow in complexity.

Nebius is deploying NVIDIA Blackwell Ultra infrastructure globally, with NVIDIA GB300 NVL72 systems and NVIDIA HGX B300 systems already in use by customers. Nebius is now the first cloud in Europe to operate both platforms in production. Additionally, Nebius AI Cloud is the first provider globally to run production GB300 NVL72 systems on 800 Gbps NVIDIA Quantum-X800 InfiniBand interconnect, which doubles throughput for distributed workloads. This infrastructure is complemented by hardware-accelerated networking and enhanced storage caching designed to eliminate infrastructure bottlenecks, and further supported by leading results in MLPerf Training v5.1 benchmarks.

To address enterprise demands for operational transparency, version 3.1 introduces Capacity Blocks and a real-time Capacity Dashboard that provide customers with complete visibility into their reserved GPU capacity and availability across all data center regions. The release also includes project-level quotas and new lifecycle object storage rules that extend granular control over resource allocation and costs.

The Nebius AI Cloud platform ecosystem continues to expand with new native integration with Dstack and simplified deployment of NVIDIA BioNeMo NIM microservices, including Boltz2, Evo-2, GenMol, and MolMIM, without requiring NGC keys or NVIDIA AI Enterprise licenses. Additional developer-focused features include enhanced Slurm-based orchestration with Manager Soperator, FOCUS-compliant billing exports, and various console user experience improvements.

The latest release builds on Aether's enterprise-ready security foundation with object storage data-plane audit logs for HIPAA compliance, per-object access controls, and VPC security groups. Enhanced IAM capabilities with Microsoft Entra ID integration and granular service roles provide stronger governance with simplified administration, supporting compliance requirements for customers in highly regulated sectors and government. Nebius will hold a technical walkthrough webinar on January 29 at 6 p.m. CET, 9 a.m. EST, and midday PST, with live Q&A.
