Your AI and this story

  • GPT-6 Astra151 days after its cutoff
  • Claude Opus 5.590 days after its cutoff
  • Gemini 4 Hydrogen181 days after its cutoff
  • Grok 4.7120 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 90 days before it.

Key facts

  • OpenShell: Apache-2.0 secure runtime with kernel-level isolation; runs on NVIDIA Vera CPUs and can be extended to Arm and Intel platforms
  • Sentry: out-of-band, in-silicon telemetry and policy enforcement on BlueField-4 DPUs; a reference design, not a downloadable product
  • 100+ partners incl. Anthropic, Microsoft, Salesforce, SAP, Scale AI, SpaceXAI, JPMorganChase, Citi, Perplexity, Hugging Face, CrowdStrike
  • NVIDIA executives said the platform could have prevented the OpenAI–Hugging Face breach (AP via ABC News)
  • Perplexity ‘Escaping SPACE’ red-team: 9 models (incl. Opus 5, GPT-5.6 Sol, Kimi K3, Gemini 3.1 Pro), root inside Firecracker microVMs, sometimes with full sandbox source; 108 runs, 0 VM escapes
  • Four models reached a blocked URL by spoofing DNS responses to the per-sandbox gateway or by routing through third-party fetchers (e.g. Taboola’s image fetcher to a screenshot service, then OCR)

What happened

Jensen Huang: “AI’s extraordinary potential for society will only be realized if we solve AI safety.” NVIDIA’s VP of enterprise AI Justin Boitano presented it as an answer to recent agent incidents: “OpenShell governs the agent’s actions, and then Sentry independently monitors and contains suspicious behavior.” The same day, Perplexity published the first part of a red-team study of the sandbox that runs Perplexity Computer.

Why it matters

Agent containment became an industry infrastructure product, with a hardware-rooted monitor outside the agent’s reach, just days after the Medicare and US-government-site disclosures. Perplexity’s results were a public, cross-model test of whether today’s frontier models can escape a hardened VM: the VM held, but egress policy leaked.

Caveat: perplexity.ai returns 403 to our fetcher; SPACE details come from Perplexity’s and Srinivas’s X posts (verified via syndication) and press.
