  • vLLM 0.30 Under Confidential Computing: What Serial Alice Found on Our H100 VM, How We Reproduced It, and the One-Variable Workaround: Serial Alice ran a full attestation test on our single-GPU H100 Confidential VM and found that vLLM 0.30 gives incoherent answers with confidential computing on, while HF transformers is correct. We reproduced it in seven runs the same day. Setting VLLM_USE_V2_MODEL_RUNNER=0 fixes it on that VM. The cause is not proven, and the limits are listed.

  • Zero Data Retention Is a Promise. Attestation Is Proof: Verifying Confidential AI in 2026: OpenAI promised zero data retention, Anthropic requires 30-day logs, and neither lets you verify anything beyond the contract. Three assurance levels, a tenant-generated Intel TDX quote verified offline against Intel, why TCB Recovery 22 and CVE-2026-33697 make attestation a process, and an 8-question checklist. Tags: Attestation, Intel TDX, Confidential GPU, GDPR.
  • Two Proofs, Zero Trust: Intel TDX and NVIDIA H200 Attestation From Inside Your Own VM: Sovereign AI needs evidence, not promises. On a single-GPU H200 Confidential VM you generate both proofs yourself: an Intel TDX quote with your own report_data, and an NVIDIA GPU attestation report bound to your nonce and verified by NVIDIA. What each proof covers, the real outputs, and the honest limits. Tags: Attestation, Intel TDX, Confidential GPU.
  • Generate Your Own Intel TDX Quote as a Tenant: Hands-On Guide (2026): On VoltageGPU Confidential VMs, /dev/tdx_guest is exposed to you, the tenant. Create a configfs TSM report, write 64 bytes of your own report_data, read back a signed TDX v4 quote, and verify it offline against Intel. No vendor API in the trust path.

  • State of Confidential AI 2026: $9.31B → $15.15B, 62.74% CAGR, and the Rise of Geopatriation: Mordor Intelligence sizes the sovereign cloud market at $9.31B in 2024 → $15.15B by 2030. Forrester puts EU sovereign AI at €1.5T cumulative through 2030. Gartner adds Geopatriation to its emerging trends. The numbers, the drivers, and what they mean for AI procurement in 2026.

  • OpenClaw Without the Node v22 Install Hell, I Put It on Telegram: OpenClaw has hundreds of thousands of GitHub stars and a maintainer who tells you the project is too dangerous if you cannot use a terminal. I tried the install three times, then built a Telegram bridge so non-terminal humans can use it for $20/mo. Tags: Intel TDX, TEE Inference, Self-Host, Confidential GPU.
  • Private ChatGPT on Telegram: How to Launch a Personal AI Agent on TDX in 2026 ($20/mo): A step-by-step launch guide for a private, GDPR-native ChatGPT alternative on Telegram. Hardware-sealed Intel TDX, EU hosted, $20/mo flat. No Ollama, no SRE, no DPA gymnastics, your token, your bot, your model, sealed. Tags: Intel TDX, GDPR, TEE Inference, Confidential GPU.
  • DORA Article 28 for AI: The 2026 ICT Register Your OpenAI Subscription Cannot Pass: BaFin’s January 2026 guidance bridges DORA and the AI Act. 6.5% of firms passed the 2024 dry-run. Senior managers now face €1M personal liability. Here’s why your OpenAI DPA fails Article 28, and what attested confidential compute produces instead. Tags: EU AI Act, Sovereign GPU, Intel TDX, Attestation.
  • HIPAA 2026: Encryption-in-Use Azure/AWS Can’t Meet: 2026 HIPAA Security Rule mandates PHI encryption "in use". Azure NCv5, AWS Nitro, CoreWeave only encrypt at rest. Intel TDX is the only fix. Tags: HIPAA, Confidential GPU, Intel TDX, TEE Inference, Pricing.
  • How to Verify Your LLM Is Actually Running in a TEE: Remote Attestation Step-by-Step: A vendor saying "we use TDX" is not evidence. A signed Intel attestation quote is. Here is the exact step-by-step process to pull a TDX quote, verify it against Intel’s root of trust, and bind your model to a specific measurement, the only proof that survives a regulator audit. Tags: Attestation, Intel TDX, TEE Inference, Confidential GPU.
  • Rent a Confidential GPU, Attest It and Verify the Proofs With Nothing but an API Key: Seven API calls, one key, no dashboard: deploy an Intel TDX VM with an NVIDIA GPU, generate the TDX quote and the GPU attestation on your own challenge, verify them on your laptop, release the machine. The run that found two gaps in our own API, what was fixed, and the exact sequence a developer or a coding agent can follow today. Tags: Attestation, Intel TDX, Confidential GPU.
  • NVSwitch Attestation on an 8x H100 Node: What Failed, Why We Were Wrong About It, and Where It Stands: On an 8x H100 node in NVIDIA Protected PCIe mode, all eight GPUs attest from inside the Intel TDX guest. The NVSwitch fabric still does not. Updated 19 September after NVIDIA answered: with the driver-matched library the NSCQ session does open and switch evidence is collected, and the failure moves to certificate validation against an unreachable OCSP responder. The logs of all three runs, including the one that proved our first explanation wrong. Tags: Attestation, Intel TDX, Confidential GPU.
  • DDRop Breaks Intel TDX With a $159 Board: What It Actually Changes If You Rent Confidential GPUs: On 14 September 2026 researchers from KU Leuven, ETH Zurich, Durham and Google broke Intel TDX with a sub-200 dollar DDR5 interposer, including forging the launch measurement. Intel calls physical attacks out of scope and plans no CVE. Here is the honest read for anyone renting confidential GPUs, including what we measured inside our own VMs. Tags: Intel TDX, Attestation, Confidential GPU.
  • Intel TDX vs AMD SEV-SNP for Confidential AI: A 2026 Technical Comparison: Two technologies, one promise: hardware-sealed AI compute. The buyer-facing pitches are nearly identical, the threat models, GPU support, attestation chains, and regulator acceptance are not. A side-by-side breakdown for teams that have to pick. Tags: Intel TDX, Confidential GPU, TEE Inference.
  • EU AI Act Compliance August 2026: Sovereign GPU & TEE Evidence: August 2, 2026 is when high-risk AI obligations bite. If you run an LLM that touches hiring, credit scoring, healthcare, legal triage, or critical infrastructure, you have weeks left, not months. Here is the real compliance map, and where hardware sealing is the only Article 15 evidence regulators actually accept. Tags: EU AI Act, Sovereign GPU, Intel TDX, Attestation.
  • Self-Host DeepSeek on Confidential GPU Cloud: TEE Inference 2026: Most teams self-hosting DeepSeek, Llama, or Qwen think they have privacy by default. They don’t. Open weights solve the model-provider trust problem and create three new ones, the hypervisor, the SRE, and the GPU bus. Here is what private inference actually requires in 2026. Tags: Self-Host, Confidential GPU, TEE Inference, Intel TDX.
  • HIPAA AI Inference: Running LLMs on Patient Data Without a BAA Nightmare: Most GPU clouds refuse to sign a BAA, or charge 4x for the privilege. Here is how Intel TDX enclaves solve HIPAA compliance at the hardware level, with real numbers. Tags: HIPAA, Confidential GPU, Intel TDX, TEE Inference.
  • GDPR AI 2026: Digital Sovereignty & Confidential GPU Cloud Fix: A Paris law firm got sanctioned in 2025 for putting client NDAs into ChatGPT. Their DPA didn’t save them. Here is why Article 28 and software-only promises fail, and how Intel TDX makes the problem go away. Tags: GDPR, Sovereign GPU, EU AI Act, Intel TDX.
  • Confidential GPU Pricing: VoltageGPU vs Azure vs AWS Nitro (Real Numbers, April 2026): I priced confidential H100, H200, and B200 across Azure, AWS Nitro Enclaves, and VoltageGPU TDX. Real numbers, no hyperscaler markup. Azure's confidential NCC H100 v5 lists at $8.90/hr (12 Sept 2026), no hyperscaler lists a confidential H200; the live VoltageGPU prices are on /pricing. Tags: Pricing, Confidential GPU, Intel TDX.
  • Confidential GPU Cloud with Intel TDX: H200 TEE Inference Guide: Intel TDX secure enclaves for H100 and H200. HIPAA technical safeguards for inference and confidential compute, 40% cheaper than Azure Confidential VMs. Tags: Intel TDX, Confidential GPU, TEE Inference.
