LLUCE.ai: Sovereign Air-Gapped LLM
Learn how LLUCE.ai, a sovereign, air-gapped, open-source LLM, was tested by DISA to significantly speed up RMF assessment package triaging, with results and findings from the pilot.
Overview
We built LLUCE.ai, a Sovereign, Air-Gapped, Open source LLM that DISA Emerging Technology & Risk Management Directorates tested. It enables the Auditor/Assessor to triage large RMF Assessment packages.

Tech stack
- LLMLarge Language Models (LLMs) are deep learning models, built on the Transformer architecture, that process and generate human-quality text and code at scale.LLMs are a class of foundation models: massive, pre-trained neural networks (often with billions to trillions of parameters) that leverage the self-attention mechanism of the Transformer architecture (introduced in 2017) to predict the next token in a sequence. Trained on vast datasets (e.g., Common Crawl's 50 billion+ web pages), these models—like GPT-4, Gemini, and Claude—acquire predictive power over syntax and semantics. They function as general-purpose sequence models, enabling critical applications such as complex content generation, language translation, and automated code completion (e.g., GitHub Copilot). Their core value: generalizing across diverse tasks with minimal task-specific fine-tuning.
- NVIDIA GPUNVIDIA GPUs are the industry-standard silicon engines powering modern artificial intelligence, high-performance computing, and real-time ray-traced gaming.NVIDIA GPUs have evolved from specialized graphics hardware into the foundational engine of modern computing. Built on advanced architectures like Blackwell and Ada Lovelace, these processors use specialized Tensor Cores and Ray Tracing Cores to accelerate complex workloads. They power everything from consumer desktops running DLSS 4.5 frame generation to massive enterprise data centers training trillion-parameter large language models. By combining high-bandwidth memory with a robust software ecosystem (most notably the CUDA platform), NVIDIA GPUs deliver the massive parallel processing power required to run modern AI, scientific simulations, and real-time 3D rendering.
- H20H2O is an open-source, distributed, in-memory machine learning platform designed to scale predictive and generative AI models across enterprise environments.H2O (specifically H2O-3) provides a fast, parallelized framework that integrates with Python, R, and Spark to handle massive datasets without breaking a sweat. Built on a distributed Java-based architecture, it automates the heavy lifting of model training through its robust AutoML engine, which handles feature engineering, algorithm selection, and hyperparameter tuning. Teams can easily export trained models as highly optimized MOJO or POJO objects for rapid, low-latency scoring in live production environments.
- RMFOpen-RMF is an open-source middleware framework that synchronizes heterogeneous robot fleets and physical building infrastructure into a single, cohesive operating system.Operating mixed-vendor robot fleets usually leads to proprietary silos and chaotic traffic jams. Open-RMF (Open Robotics Middleware Framework) solves this by providing a common translation layer built on ROS 2. The platform coordinates different robot brands (such as AMRs and AGVs) while managing shared physical assets: triggering elevators, opening automatic doors, and resolving spatial conflicts in real time. By handling task allocation and dynamic path negotiation, it transforms fragmented hardware into a unified, cooperative facility workforce.
- Air-gappedAir-gapping is the ultimate security measure: physically isolating a computer or network from the internet and all unsecured connections to make remote hacking impossible.When compromise is not an option, you cut the cord. Air-gapping physically isolates a secure network or device from the public internet, local area networks, and wireless signals (including Wi-Fi and Bluetooth). It is the gold standard for protecting high-stakes environments: military command systems, nuclear power plants, and critical financial ledgers. Because there is no digital pathway into the system, remote hackers are locked out. To move data, operators must physically transfer files via encrypted removable media or unidirectional data diodes, shifting the security battleground from digital firewalls to strict physical access control.
