Your data. Your rules. Your AI.

Private, resilient, production-grade inference — sharded across any CPU or GPU, with no trade-offs on performance, scale, or compliance.

Sovereign by Design

Data stays inside your borders. Deploy on-prem, inside your VPC, or fully air-gapped. No hyperscaler round-trips, no cross-border transfers, no third-party logging.

Runs on Your Hardware

Any GPU, any vendor, any generation, pooled into one fleet. Shard whichever model fits the total VRAM and run several side by side — no config changes, no NVLink, no InfiniBand, no hardware refresh.

Simple to Run, Hard to Break

Add or remove GPUs live — no reloads, no maintenance windows, no mid-flight collapse. Keeps serving through individual GPU failures without dropping sessions. Platform teams manage what runs on ARK, not ARK itself.

Any Modality, Any GPU

Text, vision, audio, embeddings — running together across whatever GPU generations you run. Route each modality to the silicon that fits it best: newer cards for large-context text, older ones for OCR or audio. One runtime, one cluster, every modality.

Built for Agents

Agent loops stay on the GPU. KV context is resident across turns, so you don’t re-pay the prefill tax on every call. Stateful by design — built for the way agents actually run, not stateless one-shot APIs retrofitted for long conversations.

Drops Into Your Stack

OpenAI v1 / Anthropic compatible API. One base-URL change and your existing code works — no new SDKs, no rewrites, no vendor lock-in. Already running Keycloak, ELK, or Prometheus? Keep them. Swap any platform service for your own.

Most enterprises are stuck in the pilot-to-production gap.

Stats: Deloitte · State of AI in the Enterprise, Jan 2026 · N=3,235 global leaders

AI investment is up. Production isn’t. The bottleneck isn’t model quality — it’s infrastructure. Your team can prototype on a hyperscaler in a week, then spend 18 months trying to deploy the same thing behind your firewall.

ARK is the infrastructure layer that closes that gap. Production-grade inference that runs where your data lives, sharded across any GPU, any vendor, any mix — so your team ships AI, not scaffolding.

01
Internal team proficiency

Your engineers ship AI features, not inference plumbing.

02
Pilots into production

The same stack prototypes in the cloud and runs behind your firewall. No rewire.

03
Compliance without compromise

Data residency, session-level isolation, audit-ready logs — built into the runtime.

REGULATORY COUNTDOWN

The EU AI Act is live.
High-risk compliance lands August 2, 2026.

Every high-risk AI system deployed in the EU must meet obligations for data governance, transparency, human oversight, and audit-ready logging. ARK is designed from the runtime up to satisfy those requirements — without proxies, offshore inference, or third-party API round-trips.

Inference is becoming infrastructure.
Infrastructure requires control.

Control requires ownership. Ownership does not require complexity. Let us show you what sovereign AI inference looks like when it's designed from the runtime up — not bolted on.
