VOLTAGEGPU

VoltageGPU provides confidential AI infrastructure for developers and small teams handling sensitive data. Its core offering is confidential virtual machines running NVIDIA GPUs within Intel TDX trust domains. Customers can generate and independently verify Intel and NVIDIA hardware attestations from inside their VM, using their own challenge, rather than relying on VoltageGPU as part of the trust chain. The company publishes verification evidence and offers voltage-verify, an open-source tool for checking proof bundles.

Available confidential GPU options include the RTX PRO 6000 Blackwell, H100, H200, and an 8× H100 node, with pricing listed per GPU-hour and billing by the second. VoltageGPU also offers a confidential inference API with TEE-hosted models, compatible with the OpenAI SDK, so prompts and responses are processed inside Intel TDX. For workloads that do not require confidentiality, customers can choose standard GPU instances, which VoltageGPU clearly distinguishes from its attested confidential products. The platform provides documentation, public verification results, and deployment options, with no commitment for GPU usage.
