Key features
  • OpenAI-compatible endpoint for private LLM inference
  • Hardware-encrypted VMs on Intel TDX, AMD SEV-SNP and NVIDIA GPUs
  • Client attestation verification before sending requests
  • Support for multiple open-weight models including DeepSeek, Kimi, GLM, Qwen
  • Confidential Kubernetes for data center scale deployments
  • Confidential training and fine-tuning on licensed stack
  • Root access over SSH to confidential VMs
  • Encrypted GPU communications with NVLink encryption on B200 and B300
  • Confidential agents runtime support
  • Prompt caching with cached input billing
  • Room temperature operation
  • Low power consumption
  • Quantum-enabled computing for optimization
  • Entangled photon generation
  • Photonic-inspired reservoir computing
  • Secure quantum communications
  • Thin-film lithium niobate fabrication
  • Electro-optic modulators
What makes it different
  • Prompts and model weights verified by clients with cryptographic attestation before any data is sent
  • Operator-blind inference: data remains unreadable to the company and hosting provider
  • Flexible deployment: choice of hosted cloud, rented VMs, or licensed stack on own infrastructure
  • Open-weight models only, no closed-source frontier models
  • Full cryptographic verification stack including open-source tools
  • Accessible and affordable quantum technology at room temperature
  • Practical solutions that harness quantum nature of light
  • Integrated quantum photonic solutions for real-world challenges
  • First-of-its-kind thin-film lithium niobate foundry in USA
