Sovereign AI Platform
Ultraviolet's flagship platform for private LLM deployment — inference, RAG, guardrails, TEE, governance, audit, and a production UI. Runs on your hardware. Nothing leaves your perimeter.
Sovereign AI Infrastructure AI you own.
AI you own.
Infrastructure you control.
Ultraviolet is a sovereign AI infrastructure company. Our products let you build, deploy, govern, and operate AI entirely inside your own perimeter — on hardware you control, with nothing leaving your network.

The status quo is a liability Frontier AI shouldn’t mean
Frontier AI shouldn’t mean
surrendering your data.
Every prompt sent to a hosted model is data leaving your control. For regulated and sovereign organizations, that’s not a feature trade-off — it’s an unacceptable risk.
Hosted AI APIsUltraviolet
Where do prompts go? ✕To a third-party cloud, logged and retained on someone else's terms. Never leave your perimeter. Zero outbound by default.
Who can see your data? ✕The provider, their subprocessors, and a foreign jurisdiction. Only you. Hardware-isolated inside Trusted Execution Environments.
Can you prove compliance? ✕You inherit a vendor's policies and hope for the best. Compliance by architecture — GDPR, HIPAA, the EU AI Act.
What happens at renewal? ✕Prices rise, models change, lock-in deepens. Apache 2.0. Own it, fork it, run it forever.
Products
Three products.
Three products.
Built to work as one.
Ultraviolet builds three sovereign AI products. Cube AI is the flagship platform. Prism AI adds secure collaboration across organizations. Cocos AI is the open confidential-computing foundation beneath them — together, AI you can fully own.
Secure AI Collaboration
Run joint AI workloads across organizational boundaries without exposing data. Multi-party computation inside Trusted Execution Environments, with free and enterprise tiers.
Confidential Computing Foundation
The open-source hardware abstraction layer for TEEs — the auditable confidential-computing substrate the rest of the stack runs on.

Cube AI — Flagship
Your AI operating environment,
Your AI operating environment,
running entirely on your hardware.
Cube AI is the full-stack platform for sovereign AI: inference, retrieval, guardrails, TEE, governance, audit, and a production-ready workspace — deployed inside your perimeter and governed by your policies, not a vendor’s terms of service.
Private inference
vLLM and Ollama runtimes serving open models on your own GPUs — no API keys, no egress.
RAG on your data
Connect internal knowledge bases with retrieval that never copies a byte off-prem.
Guardrails & policy
NeMo-based guardrails and policy enforcement on every prompt and response.
Governance & audit
Full audit trail, role-based access, and usage accounting built into the platform.
Hardware TEE
Run the whole stack inside AMD SEV-SNP or Intel TDX enclaves — weights and tensors stay encrypted in use.

On-premises
Run on your own servers and GPUs, behind your firewall, under your change control.
Same platform · same governance · same audit trail
Collaborate on AI
without exposing data.
Prism AI runs joint AI workloads across organizational boundaries inside Trusted Execution Environments. Each party keeps its data private while sharing only the result. A commercial platform with free and enterprise tiers.
The open foundation
the stack runs on.
Cocos AI is the open-source hardware abstraction layer for Trusted Execution Environments — the transparent, auditable substrate beneath Cube and Prism. Inspect it, fork it, extend it.

Three commitments
behind every product.
01
Private
Every prompt, embedding, and response stays inside your perimeter. Zero outbound by default. No hidden telemetry, no training on your data.
02
Sovereign
Data residency, compliance, and operational control governed by your policies and your jurisdiction — never a vendor's terms of service.
03
Open
Open core. Cube AI and Cocos AI are Apache 2.0 — inspect the source, fork the platform, extend it for your environment. No black boxes, no lock-in.
Trust, by architecture Compliance you can prove —
Compliance you can prove —
not just promise.
Sovereignty is enforced in hardware. Trusted Execution Environments isolate every workload, remote attestation makes that isolation verifiable, and a complete audit trail makes it provable to a regulator. Validated through three EU Horizon Europe research projects and built as a member of the Linux Foundation and Confidential Computing Consortium.
