On-premises AI that passes every audit
A rack appliance that moves from unboxing to production in about 15 minutes, keeping all inference and data on site.
An operating system for private AI deployment that lets you choose and govern models on your own infrastructure.
Index data across core systems, document stores and data warehouses without moving it, enabling real-time retrieval with zero egress.
An enterprise assistant that answers policy, customer and compliance questions with logged, auditable responses.

The durable AI runtime that runs in your cloud, not ours
Tasks, traces and artifacts survive infrastructure failure. Runs fork, recover and replay from the last good step instead of starting over, with retries and caching handled by the runtime.
Named, typed and versioned artifacts wire teams together, with lineage showing which run produced each version and which downstream tasks consume it.
Run the control plane in Union's cloud while workloads execute on clusters in your AWS, GCP, Azure or neocloud account, under your own security perimeter.
Bring OpenAI, Claude, PydanticAI or CrewAI agents; each turn is traced and sandboxed in ephemeral containers, MCP servers and human approvals supported.
