## Summary

Nvidia announced the Confidential Bare Metal option for its Confidential Computing platform, letting frontier model builders run sensitive workloads on dedicated third‑party bare‑metal servers while keeping full control of models and data. The new deployment adds hardware‑rooted isolation, cryptographic attestation, and platform‑integrity checks across Nvidia’s Grace Blackwell, Rubin and other systems.

Cohere said it will embed Confidential Bare Metal into its Model Vault, extending hardware‑rooted security to the GPU. Google Cloud also announced support for Confidential Bare Metal on its A4X Max instances powered by Nvidia GB300 NVL72 systems, promising end‑to‑end cryptographic protection for training data and model IP. A broad ecosystem of cloud and hardware partners, including CoreWeave, Firmus, GMI Cloud, Lambda, Microsoft Azure, and others, now supports the expanded Confidential Computing modes.

## Key points

- Nvidia introduced Confidential Bare Metal, a new deployment option for its Confidential Computing platform.
- Confidential Bare Metal enables model builders to run workloads on dedicated third‑party bare‑metal servers with hardware‑rooted security.
- Cohere and Google Cloud announced integration of Confidential Bare Metal into Cohere Model Vault and Google Cloud A4X Max instances.

## Why it matters

Hardware‑rooted security for AI models lets companies protect IP and data while scaling training and inference across clouds, a growing need for enterprise AI.
