Confidential VM tier

The only GPU tier whereyou generate the attestation.

A full Intel TDX virtual machine, Ubuntu 24.04, full root over SSH, GPU attached. Inside it, /dev/tdx_guest belongs to you: generate your own signed TDX quote with your own 64-byte challenge, and verify it offline against Intel, never against us.

§ 01 / method

Five commands, verified end to end

No vendor SDK, no API of ours in the loop. Just the Linux kernel’s standard configfs TSM interface. Verified live on September 3, 2026.

verified live on a Confidential VM
# Inside your Confidential VM (Ubuntu 24.04, Intel TDX)
ls -l /dev/tdx_guest
lsmod | grep -E "tdx_guest|tsm"

# Generate a quote with YOUR 64-byte challenge
sudo mkdir /sys/kernel/config/tsm/report/r1
sudo dd if=report_data.bin of=.../r1/inblob
sudo cat .../r1/outblob > quote.bin   # 5,247 bytes, TDX quote v4

# Verify OFFLINE with Intel DCAP, against Intel's root CA.
# We are not in the trust path.

Confidential VM pricing

Per-second billing, no minimum. Priced above the container tier because tenant-side attestation is a distinct capability nothing else on the market offers at this price point, Azure confidential GPU runs roughly $12.50/hr.

§ 04 / use cases

What tenant-generated quotes unlock

Audit evidence you cannot fabricate after the fact
Generate a quote with a nonce-bound report_data at audit time. The evidence cannot have pre-existed the request, and the auditor can run the five commands personally.
Regulated batch workloads with a paper trail
Bind a fresh, nonce-bound quote to every processing session and archive it next to your logs, for GDPR Article 32, financial audit trails, or clinical data handling.
Application-level attestation chains
Because report_data is yours, you can embed the hash of a model output or a signed document into a fresh quote, proof that exact result was known inside that exact Trust Domain.

§ 05 / honest limits

What this does not give you today

GPU CC state is OFF
The quote attests the CPU TEE boundary, not the GPU. Never treat a TDX quote as GPU-side evidence.
No persistent volumes yet
Treat the VM disk as ephemeral. Copy your quotes and artifacts off the box before the session ends.
No self-serve deploy UI yet
Provisioning is by email while the UI is being built. This page will get a Deploy button when it ships.

FAQ

Common questions

How is this different from the standard confidential container tier?

The container tier does not expose /dev/tdx_guest inside your workload. CPU attestation exists at the infrastructure level there, but you cannot generate a tenant quote with your own report_data from inside a container. The Confidential VM tier gives you the device directly, with full root over SSH.

Does the attestation quote cover the GPU?

No. GPU confidential computing (CC state) is currently off on these VMs. The TDX quote attests the CPU TEE boundary, the Trust Domain, its measurements, and your report_data. It does not attest the GPU, and we never represent it as GPU-side evidence.

Can our own auditors run the verification themselves?

Yes, that is the entire point. SSH access and full root are included. An auditor can generate their own nonce-bound quote and verify it offline with Intel DCAP against Intel’s root CA, with no VoltageGPU API or credential anywhere in that chain.

How fast can we get a VM?

Provisioning is currently on request while the self-serve deploy UI is being built. Email contact@voltagegpu.com and a VM is typically ready the same day.

Are there persistent volumes?

Not yet on this tier. Treat the VM disk as ephemeral and copy quotes and artifacts off the box before the session ends. Persistent volumes are on the roadmap alongside the deploy UI.

Confidential VMs are provisioned on request while the deploy UI is in progress. Email us and generate your first tenant-side TDX quote the same day.

Security for Sensitive Data, Full Technical Details

The Confidential Agent Platform runs on Intel TDX (Trust Domain Extensions) hardware enclaves with NVIDIA H200 GPUs attached inside the trust domain (GPU confidential-computing mode not enabled yet). The security stack: (1) Intel TDX encrypts RAM with hardware-fused CPU keys, the hypervisor is OUTSIDE the trust boundary and physically cannot access TD memory. (2) trust-domain GPU passthrough creates an encrypted CPU-to-GPU channel preventing bus snooping. (3) LUKS encrypted filesystem, decryption key released ONLY after successful remote attestation. (4) Remote attestation: Intel TD Quote (signed by CPU-fused private key) verified against Intel public keys plus NVIDIA GPU attestation plus proof of VRAM work. Only PERFECT measurement matches pass. (5) Post-quantum end-to-end encryption for prompts and responses. (6) Model verification cryptographically proves every output token came from the declared TEE model, defeating model substitution attacks. (7) Continuous monitoring with random integrity challenges and immediate node removal on failure. Real-time public attestation reports available. This is not software security, it is silicon-level isolation verified by Intel and NVIDIA hardware attestation. EU company (France), GDPR Art. 25, Intel TDX hardware attestation.

Not Limited to 9 Templates, Connect Your Own Agent

The 9 templates are starting points. Any OpenAI-compatible agent works: OpenClaw (247K+ GitHub stars), CrewAI (50K+), LangChain (100K+), or any custom agent. Change one line (base_url) and every LLM call runs inside a TDX enclave. The platform is an API, not a closed system.

Model Quality, Not Just LLM Output

Three model tiers: Free uses Qwen3-32B-TEE (32B params, 40K ctx), Plus / Team Starter / Pro use Qwen3.5-397B-TEE (397B MoE, 256K ctx, can ingest entire contracts), Enterprise uses DeepSeek-R1-TEE (reasoning model with chain-of-thought for CFA-grade analysis). The key differentiator is the TOOLS, not just the model. Tools are deterministic server-side code: the clause checklist runs exact IACCM/ABA rules, the risk score uses a fixed formula (critical x25, high x15, medium x8), the market benchmark compares against 12 real 2024-2026 deal data points. The LLM orchestrates which tools to use, but the tools produce exact, verifiable results. Model verification (cllmv) cryptographically proves every output token came from the declared TEE model.

Performance, No TDX Overhead in Practice

Intel TDX adds 3-7% overhead theoretically. In practice, VoltageGPU uses 8x NVIDIA H200 140GB (top-tier GPU) which more than compensates. Analysis completes in approximately 6 seconds. The warm-tdx system keeps enclaves pre-heated, zero cold start for subscribers. Per-second billing means you only pay for actual compute time.

Competitive Comparison

Confidential Compute: VoltageGPU TDX H200 $6.58/hr vs Azure Confidential H100 $14/hr. Legal AI: VoltageGPU $349/month vs Harvey AI $1,200/seat/month. Confidential GPU Compute: H100 from $5.00/hr, H200 from $6.58/hr, B200 from $10.60/hr.
