## Summary

Palantir and Nvidia have expanded their partnership to create a "sovereign AI" operating system reference architecture, specifically designed for US government agencies and critical infrastructure operators. The solution integrates Nvidia’s open Nemotron models and AI Enterprise software with Palantir’s AIP, Foundry, and Rubix zero-trust security layers. This setup allows organizations to run powerful AI models on-premises or in sovereign clouds, ensuring that sensitive or classified data never leaves their secure perimeters.

The collaboration addresses significant concerns regarding data sovereignty, particularly for defense sectors that cannot rely on closed commercial models due to risks of data leakage to third-party providers. By utilizing open models, agencies can fine-tune AI on proprietary data without exposing model weights or operational insights. The architecture supports on-premises, edge, and cloud deployments, featuring explicit authorization protocols, customer isolation, and full auditability to meet strict national security standards.

The hardware foundation relies on Nvidia Blackwell Ultra systems with 8 GPUs per node and Spectrum-X networking. A key addition to this expanded partnership is the integration of supply chain optimization capabilities using Nvidia’s cuOpt engine. Nvidia has already deployed this stack internally to manage its global supplier network, which involves handling the complexity of 1.3 million parts per AI rack, demonstrating the system’s practical utility in high-stakes logistics environments.

## Key points

- Palantir and Nvidia integrated Nemotron models with Palantir platforms to create a secure, on-premises sovereign AI stack.
- The architecture targets US government and critical infrastructure, ensuring zero data leakage via zero-trust security and air-gapped support.
- Nvidia deployed the stack internally to optimize its supply chain, managing 1.3 million parts per AI rack using cuOpt.

## Why it matters

This partnership offers a viable alternative to closed commercial AI for sensitive government use cases, addressing critical data sovereignty and national security concerns by enabling secure, on-premises model deployment.
