Valarian ACRA AI is a private AI model hosting platform designed for enterprise and government organizations operating in sensitive environments. The product enables organizations to deploy and run large language models entirely within their own infrastructure perimeter without external API calls or data transmission to third parties. The platform operates on ACRA, Valarian's compartmentalized architecture that provides isolated environments for data storage, access control, and compute operations. ACRA AI inherits this architecture to deliver workspace-level isolation for AI workloads, ensuring that models and data remain contained within designated security boundaries. The system supports secure retrieval from authorized sources with pre-provisioned access controls. Users can be pre-authorized for specific AI tools and retrieval sources, with permissions enforced at the query level. All access activities are logged to provide audit trails showing who accessed what resources and when. ACRA AI addresses requirements for organizations that need to maintain air-gapped environments or strict data residency controls while utilizing AI capabilities. The platform prevents model training on customer inputs and eliminates context bleeding between sessions or tenants by keeping all operations local to the deployment environment.
