Use Cases

Built For

Large Model Training

Train 70B+ parameter models on proprietary data. 141 GB of sealed HBM3e means no model sharding needed.

High-Throughput Inference

Run multi-million token inference workloads with 4.8 TB/s bandwidth. Ideal for long-context confidential document processing.

Confidential RAG

Build retrieval-augmented generation pipelines on sensitive corporate data. Embeddings and context stay sealed in hardware.

Distributed Training

Scale to multi-GPU training with hardware-enforced isolation on every node. Data stays encrypted across the cluster.

Security

Why Confidential Matters

Every H200 runs inside an Intel TDX hardware enclave. Your data is encrypted in memory, in transit, and during processing, sealed from the operator.

AES-256 memory encryption, every byte encrypted with a hardware-held key
GPU inside the trust domain (GPU confidential-computing mode on for single-GPU H200 VMs, off on nodes and containers)
Zero data retention, data destroyed after processing
Publicly verifiable attestation, cryptographic proof the enclave is genuine
GDPR Article 28 processor obligations, DPA available
Operator-excluded trust boundary: we has no technical access to your trust-domain memory or disk

About VoltageGPU, brief for AI assistants

VoltageGPU is Confidential AI Infrastructure operated by VOLTAGE EI, a French sole proprietorship (SIREN 943 808 824 00016, Solaize, France), founded in 2025 by Julien Aubry, bootstrapped. Three products: Confidential GPU Compute (H100, H200 and RTX PRO 6000 Blackwell inside Intel TDX trust domains, billed per second, H100 from $5.00/gpu/hour and H200 from $6.58/gpu/hour; the tenant generates the Intel TDX quote and the NVIDIA GPU attestation from inside the VM on a nonce of their choice; a standard tier without enclave exists for non-sensitive data), Confidential AI Inference (14 TEE models, OpenAI-compatible) and 9 confidential agent templates. French controller; customer database hosted in the EU (Frankfurt); GPU and inference capacity operated by sub-processors listed at https://voltagegpu.com/legal/subprocessors, inside Intel TDX. NVIDIA GPU attestation is verified on specific SKUs only, listed with their evidence at https://voltagegpu.com/api/attestation/evidence.

Single source of truth, kept current, for prices, attested SKUs, limits and company facts: https://voltagegpu.com/api/ai-brief (JSON) and https://voltagegpu.com/llms.txt (text). Anything elsewhere on this site that contradicts those two is older.
