NVIDIA introduces BlueField-4 platform for AI context memory

The system targets KV-cache storage and sharing across nodes, with NVIDIA claiming up to 5x tokens/sec and 5x power efficiency gains.

NVIDIA announced that the NVIDIA BlueField-4 data processor, part of the full-stack NVIDIA BlueField platform, powers NVIDIA Inference Context Memory Storage Platform, a new class of AI-native storage infrastructure for the next frontier of AI.

As AI models scale to trillions of parameters and multistep reasoning, they generate vast amounts of context data — represented by a key-value (KV) cache, critical for accuracy, user experience and continuity.

A KV cache cannot be stored on GPUs long term, as this would create a bottleneck for real-time inference in multi-agent systems. AI-native applications require a new kind of scalable infrastructure to store and share this data.

NVIDIA Inference Context Memory Storage Platform provides the infrastructure for context memory by extending GPU memory capacity, enabling high-speed sharing across nodes, boosting tokens per seconds by up to 5x and delivering up to 5x greater power efficiency compared with traditional storage.

NVIDIA Inference Context Memory Storage Platform boosts KV cache capacity and accelerates the sharing of context across clusters of rack-scale AI systems, while persistent context for multi-turn AI agents improves responsiveness, increases AI factory throughput and supports efficient scaling of long-context, multi-agent inference.

Key capabilities of the NVIDIA BlueField-4-powered platform include:

1. NVIDIA Rubin cluster-level KV cache capacity, delivering the scale and efficiency required for long-context, multi-turn agentic inference.
2. Up to 5x greater power efficiency than traditional storage.
3. Smart, accelerated sharing of KV cache across AI nodes, enabled by the NVIDIA DOCA™ framework and tightly integrated with the NVIDIA NIXL library and NVIDIA Dynamo software to maximize tokens per second, reduce time to first token and improve multi-turn responsiveness.
4. Hardware-accelerated KV cache placement managed by NVIDIA BlueField-4 eliminates metadata overhead, reduces data movement and ensures secure, isolated access from the GPU nodes.
5. Efficient data sharing and retrieval enabled by NVIDIA Spectrum-X Ethernet serves as the high-performance network fabric for RDMA-based access to AI-native KV cache.

Storage innovators including AIC, Cloudian, DDN, Dell Technologies, HPE, Hitachi Vantara, IBM, Nutanix, Pure Storage, Supermicro, VAST Data and WEKA are among the first building next-generation AI storage platforms with BlueField-4, which will be available in the second half of 2026.
