The frontier operating platform for agentic AI and token optimisation.
Regulated organisations are moving agentic AI into production, but most lack control at the point of execution: policy enforcement on every agent call, real-time token cost control, architecture-aware compliance and sovereign control of inference and evidence.
When an incident happens, the evidence collection is scattered across provider logs, applications, approvals, security tools and cloud platforms.
The Grace Blackwell Platform closes this gap by combining Sovereign Edge IDN with HEX 165. IDN hosts sensitive workloads inside the approved UK / EU region. HEX 165 governs what runs on it: enforcing policy, assessing compliance, monitoring runtime behaviour, controlling token flow, optimising cost and recording every material decision to an immutable audit log.
The result is production AI that regulated enterprises can control, measure, evidence and trust.
The Sovereign Edge IDN provides the UK / EU sovereign infrastructure for hosting sensitive AI workloads. HEX 165 governs what runs on that infrastructure: controlling agents, tokens, compliance, runtime security, inference optimisation and audit evidence.
Each can be procured independently, but together they form a complete sovereign operating system for agentic AI in regulated environments.
A sovereign hosting environment with the Inference Distribution Network (IDN) at its core. Five platform layers operate inside the approved UK / EU region, with deployment options ranging from sovereign connected environments to fully air-gapped operation for the most sensitive workloads.
Data, models, prompts, logs, telemetry and encryption keys remain in region. Where air-gap mode is selected, inbound and outbound connectivity is disabled by design, with ingress and egress controlled through approved transfer procedures.
Explore the Sovereign Edge IDNThe operating platform that runs on the IDN substrate. Four engines govern policy, compliance, runtime security and token cost. Every agent call is enforced, scanned, monitored and priced, with a hash-chained audit log generated by design.
HEX 165 moves AI governance below the application layer and into the execution path itself. It controls what agents are allowed to do, what context reaches the model, how tokens are routed and optimised, when human approval is required, and what evidence is retained for audit, compliance and operational review.
