Cohere has opened a public beta of Confidential Computing on Cohere Model Vault, its fully managed inference platform, for enterprises that process sensitive data. The service runs on NVIDIA H100 GPUs on Microsoft Azure and extends Model Vault to workloads such as clinical records, financial information, privileged documents, intellectual property and proprietary source code. Cohere says the goal is to give enterprises managed AI's capabilities and operational simplicity while keeping sensitive plaintext out of reach of the infrastructure running the service. The model-serving stack, including the operating system, drivers and inference server, runs inside a confidential virtual machine, and NVIDIA Confidential Computing protects GPU memory and encrypts CPU-to-GPU traffic. Requests are encrypted with Oblivious HTTP to a public key tied to the attested environment, so intermediaries route traffic without seeing plaintext payloads. Before each protected request, the environment produces signed evidence that customer-side software checks against an approved policy; if a property does not match, the client refuses to transmit the payload. Cohere says the trusted computing base still includes the hardware and firmware, the measured software, the reference measurements and the attestation infrastructure, and that physical and side-channel attacks remain outside the boundary.

## Evidence

Verbatim from https://www.unite.ai/cohere-launches-confidential-computing-on-model-vault-in-public-beta/:

> In Model Vault, the model-serving stack, including the operating system, drivers, and inference server, runs inside a confidential virtual machine, where hardware-backed isolation shields its memory from the host environment and policy limits the environment to approved software while giving operators no interactive path into the running workload
