Key takeaways
  • 01 Sovereign deployment options across AWS, Azure, GCP, and on-prem stacks.
  • 02 Model risk artefacts that your central bank or NESA equivalent will accept.
  • 03 Three live-deployed reference patterns from public-sector and BFS programmes.
Section 01

Why sovereignty matters now

Recent regulatory shifts in the GCC, KSA, and India have made sovereign deployment of LLMs a programmatic requirement rather than a procurement preference. This whitepaper walks through the architectural choices that determine whether sovereignty is a constraint or an accelerator.

Section 02

Reference architecture

A four-tier reference: data residency layer, model gateway, content firewall, evaluation harness. Each tier is composed of well-known open-source and managed components, with proven deployment patterns in three jurisdictions.

Section 03

Model risk and explainability

Extending SR 11-7 controls to retrieval-augmented LLM systems. We document the six artefacts our regulators have accepted on first review, with template language ready for adoption.

Section 04

Operating model

Sovereign deployment changes who can see what, when. The whitepaper covers RACI, audit packs, and the controls that make sovereignty operationally sustainable rather than a compliance ceiling.

Section 05

Lessons from production

Three case studies — a sovereign bank, a federal agency, a regulator — with the specific architectural choices made and the trade-offs accepted.
