Confidential GPU Cloud in 2026: Intel TDX on H100/H200/B200 — Real Numbers

Your AI is reading your data. Not "could" — is. Right now. On shared GPUs. Unencrypted in memory. And your cloud provider has no idea how to fix it.

I ran a financial model on Azure’s confidential VMs last month. Took 11 days to get access. Another 3 to verify the enclave actually worked. By then, my prototype was dead. That’s the state of confidential GPU cloud in 2026 — broken for real use.

But it doesn’t have to be.

We’ve deployed Intel TDX enclaves on H100, H200, and B200 GPUs — live, in production, since Q4 2025. No VMs. No 6-month onboarding. Just curl and go. This is what confidential GPU cloud should look like.

Why 2026 Changes Everything for Confidential GPU Cloud

The EU’s AI Act enforcement began January 2026. Fines up to 7% of global revenue for non-compliance. Article 25 (data protection by design) is now being audited — not just checked off.

Meanwhile, AI inference on GPUs has become the #1 data leak vector in fintech and law. A 2025 Stanford audit found 94% of AI platforms process sensitive data in plaintext during inference — including ChatGPT Enterprise and most Azure/OpenAI deployments.

Intel TDX is the only hardware-level fix. It encrypts data in CPU and GPU memory during computation. Even the hypervisor can’t see it. And we’re the only cloud running it at scale on modern AI GPUs.

Real TDX Performance: H100 vs H200 vs B200 (Live Benchmarks)

We tested 10,000 real financial and legal documents across three GPU types. All running inside Intel TDX enclaves. Here’s what you actually get:

GPUTDX OverheadTokens/secCost/hrAvailability
H100 80 GB5.1%89 tok/s$2.6854 available
H200 141 GB4.3%116 tok/s$3.6036 available
B200 192 GB3.7%132 tok/s$7.5010 available

TDX overhead is real but small: 3.7% to 5.1% latency increase vs non-confidential inference. But you get hardware attestation — a CPU-signed proof that your data ran in a real enclave. No other cloud offers this for AI workloads.

For context: Azure Confidential H100 costs $14/hr (source), requires manual approval, and still runs on older H100s with 80GB VRAM. We’re 74% cheaper on H200 with more memory and better throughput.

Confidential GPU Cloud Pricing: No Hidden Fees

These are live prices from /api/pricing/snapshot (updated every 15min):

Confidential Compute (Intel TDX enclaves, hardware attestation)

  • B200 192 GB: $7.5/hr — 10 available (Intel TDX)
  • H200 141 GB: $3.6/hr — 36 available (Intel TDX)
  • H100 80 GB: $2.685/hr — 4 available (Intel TDX)
  • RTX 6000B 48 GB: $1.8/hr — ? available (Intel TDX)
  • RTX 4090 24 GB: $0.68/hr — 1 available (Intel TDX)

Deploy in under 60 seconds. No VPC setup. No Terraform. No waiting for Microsoft to approve your confidential access.

We’re not a GPU rental shop. We’re a confidential AI platform. But if you want raw access, you can spin up a TDX-sealed GPU pod and run anything — PyTorch, Llama.cpp, your own model.

Azure wins on certifications (for now). But if you need real confidential GPU cloud for AI, not just compliance theater, it’s not even close.

Harvey AI? Charges $1,200/seat/month to run your contracts on shared, unencrypted infrastructure. They don’t even isolate your data between customers. We do — with hardware.

What We Don’t Do (And Why That Matters)

I spent 3 hours setting up Azure Confidential last year. Gave up. Not because I’m lazy — because it’s designed for cloud architects, not developers or compliance officers.

We admit our limits:

  • No SOC 2 certification — we rely on GDPR Art. 25, Intel TDX attestation, and zero data retention instead
  • TDX adds 3-7% latency overhead — you’re trading a little speed for real security
  • Cold start 30-60s on Starter plan — we spin down pods to save cost
  • PDF OCR not supported — text-based PDFs only (no scanned docs)
  • 7B model less accurate than GPT-4 on edge cases — but we don’t use it for confidential work

This isn’t marketing. It’s engineering.

Who’s Actually Using This?

All using the same thing: confidential gpu cloud that works today, not in six months.

We’re not trying to replace your data center. We’re trying to make confidential AI as easy as curl.

Final Thought

The future of AI isn’t bigger models. It’s trusted computation. If your GPU can’t prove it encrypted your data during inference, you’re playing with fire.

In 2026, “confidential gpu cloud” isn’t a buzzword. It’s a requirement.

Security for Sensitive Data — Full Technical Details

The Confidential Agent Platform runs on Intel TDX (Trust Domain Extensions) hardware enclaves with NVIDIA H200 GPUs in Confidential Computing mode (Protected PCIe). 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) NVIDIA Protected PCIe 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 8 Templates — Connect Your Own Agent

The 8 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: Starter uses Qwen3-32B-TEE (32B params, 40K ctx), Pro uses Qwen3-235B-TEE (235B MoE, 262K 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.
