Nebius said the interconnect doubles throughput for distributed workloads and, together with hardware-accelerated networking and enhanced storage caching, helps eliminate infrastructure bottlenecks. The platform also complements Nebius' leading results in MLPerf Training v5.1 benchmarks. Capacity Blocks Add Transparency for Enterprise AI As customers move from experimentation to scaled deployment, Nebius said demand is rising for real-time GPU visibility, predictable resource allocation and multi-team governance. Version 3.1 introduces Capacity Blocks and a real-time Capacity Dashboard, giving customers visibility into reserved GPU capacity and availability across all regions. Project-level quotas and new lifecycle object storage rules further extend granular control over resource allocation and costs. Expanded Developer Tools and Ecosystem Integrations Nebius AI Cloud 3.1 expands its ecosystem with native Dstack integration and simplified access to NVIDIA BioNeMo NIM microservices, including Boltz2, Evo-2, GenMol and MolMIM, without requiring NGC keys or NVIDIA AI Enterprise licenses. Additional enhancements include improved Slurm-based orchestration with Manager Soperator, FOCUS-compliant billing exports and console user-experience updates. The release strengthens Aether's enterprise security foundation with object storage data-plane audit logs for HIPAA-compliant configurations, per-object access controls, VPC security groups and enhanced IAM with Microsoft Entra ID integration and granular service roles.
