Sovereign AI Inference
Query foundation models hosted outside your jurisdiction without the prompt or response leaving home — Schrems II / FedRAMP High / DoD IL5 / EU AI Act Article 16 conformance via cryptography rather than via dedicated sovereign clouds.
The problem to solve
Sovereign AI strategy depends on running serious workloads on the best available models. The best frontier models often run on non-sovereign infrastructure. The contradiction is built in: every query, every prompt, every response leaves the home jurisdiction in plaintext. Schrems II + FedRAMP High + DoD IL5/IL6 + EU AI Act Article 16 set sharper bars on cross-border exposure than the current generation of model APIs can satisfy. A government department that wants the frontier capability typically surrenders the sovereignty bar; a department that wants the sovereignty stands up an in-jurisdiction sovereign cloud at multiples of the cost and lags one model generation behind.
The solution it enables
Polymonial seals the query, the inference, and the response. The model provider runs inference over sealed prompts and returns sealed outputs. The plaintext is reconstructed inside the home jurisdiction — not on the non-sovereign cloud. The model owner sees ciphertext; the sovereign user sees the answer. The Schrems II / FedRAMP High residual-risk concern shifts from policy + paperwork to cryptography: the data physically can't be misused outside the schema-permitted query.
What it looks like
A UK government department under UK Govt AI Playbook constraints needs to query a US-hosted foundation model on classified policy material. Their prompt is sealed before it leaves UK soil. The US provider runs inference on the sealed prompt and returns a sealed response. The plaintext output is reconstructed only inside the department's UK environment. Provider logs show ciphertext only — no policy briefing, no draft analysis, no sensitive query has crossed the border in plaintext. EU AI Act Article 16 high-risk conformance evidence — provenance of inference, audit trail of queries — is generated as a byproduct of the schema, not as a separate stream.
“The query stays in the home jurisdiction. The model runs wherever. Sovereign AI without a sovereign cloud.”
