Release Notes#

These Release Notes describe the key features, software enhancements and improvements for the NVIDIA Halos Outside-In Safety releases.

1.2.1 EA#

This early access (EA) update builds on 1.2. The Halos Outside-In Safety codebase is now open source, the reference perception pipeline has been upgraded to VSS Warehouse Blueprint 3.2.0, and the packaging and deployment guidance has been refreshed. Some features remain in an alpha state and should not be used in production.

Key Features and Enhancements#

Open-source availability on GitHub#

  • The Halos Outside-In Safety source code is now available as open source on GitHub at NVIDIA/halos-outside-in-safety. The repository covers the Safety Core, reference applications, the closed-loop testing harness, and the deployment skill, and complements the Debian packages and container images distributed through NGC.

VSS Warehouse Blueprint 3.2.0 upgrade#

  • Upgraded the reference AI perception source from VSS Warehouse Blueprint 3.1.0 to 3.2.0, including all related documentation references.

  • VSS Warehouse is now deployed from its public GitHub repository. The Quick Start Guide and the closed-loop (SIL/HIL) testing guides have been updated for the new deployment flow, service names, environment settings, and 2D and 3D perception configuration.

Deployment skill updates#

  • The deployment skill for coding agents (such as Claude Code, Codex, and Cursor) is now part of the open-source repository as a single hoisa-deploy-profile skill that deploys Halos by profile: base (Safety Core on an existing perception feed, on x86 or on IGX Thor with the decision-maker on CCPLEX or FSI) and sil (full closed loop). The VSS Warehouse 3.2.0 perception backend is deployed first via the separate vss-deploy-profile skill from the VSS Warehouse Blueprint.

Packaging and distribution updates#

  • Safety Core packages and container images are now published in NGC under nvidia/halos-outside-in (with the gated FSI firmware package under nvidia/outside-in-safety), at version 1.2.1.

  • The fsicom-agent host bridge now ships in the psf-tegra-fsi.deb package.

Safety-flashed IGX Thor deployment guidance#

  • Added guidance for deploying the VSS Warehouse Blueprint - 2D profile on safety-flashed IGX Thor systems, including container runtime and image pull workarounds. See Annex A of the HOISA Quick Start Guide for details.

1.2 EA#

This is an early access (EA) release including a refactored architecture and new features. There are some features in an alpha state and should not be used in production.

Key Features and Enhancements#

Safety Decision Maker on FSI for IGX#

  • Added support for running the Safety Decision Maker (SDM) on the Functional Safety Island (FSI) for IGX platforms.

Safety AI Monitor (Preview)#

  • Added Safety AI Monitor, supported on GPU only, to validate input video for Out-of-Distribution (OOD) and camera blockage detection.

Proximity monitoring reference application#

  • Added a new Proximity Monitoring reference application for proximity detection between a human operator and robot.

Safety Core updates#

  • Added performance and functional safety updates and bug fixes to HOISA Safety Core components.

Closed-loop testing harness updates#

  • Added support for Hardware-in-the-Loop (HIL) testing

  • Added support for deployment support via agentic skills and coding agent platforms (Claude, Codex, etc.) (Preview)

  • Added support for 3D vision AI perception pipeline (Preview)

1.1 EA#

This is an early access (EA) release including a refactored architecture and new features. There are some features in an alpha state and should not be used in production.

Key Features and Enhancements#

New reference applications for safety control#

  • Introduced a reference Automated Trailer Loading (ATL) application that uses HOISA Safety Core to control a forklift’s safety function based on outside-in perception of humans inside and around the trailer.

Software-in-Loop (SIL) testing support#

  • Added end-to-end Software-in-Loop (SIL) testing that validates the Halos Outside-In Safety system using Isaac Sim.

  • SIL runs the real VSS Warehouse Blueprint, Safety Event Integrator, Safety Decision Maker, and communication layer against simulated warehouse, forklift, humans, and camera streams to safely exercise safety logic and failure scenarios.

Multi-camera and multi-pipeline fusion#

  • Enhanced Safety Event Integrator (SEI) logic to support fusion of events from multiple cameras and redundant perception pipelines.

Outside-In safety with VSS Warehouse Blueprint#

  • Integrated HOISA with the VSS Warehouse Blueprint – 2D Vision AI profile to use RT-DETR–based detection, tracking, and ROI/tripwire analytics as the primary safety perception source.
