About NVIDIA Personal AI Router

Local inference router for a group of compatible computers
Release info Update on Oct 13, 2026
Release notes This release brings llama.cpp and RTX Spark support to PAIR, and establishes
its public development and contribution workflow on GitHub.

What's New
• llama.cpp support. Install and manage llama.cpp directly from PAIR,
download compatible GGUF models from Hugging Face, and route inference
requests across paired devices. Refer to
Managing Engines.
• Engine launch options. Customize the launch arguments and environment
variables of PAIR-managed engines, on this device or a paired one. Tune
settings such as context size where the engine supports them. Refer to
Engine Settings.
• RTX Spark support. PAIR's Windows on ARM build has been validated with
llama.cpp and CUDA on RTX Spark N1X hardware.
• Improved terminal experience. The terminal interface has a redesigned
layout organized around each device, so you can manage engines, download
models, and pair devices from one place. A new Jobs tab follows inference
work across paired devices and runs the Inference Demo, giving headless
machines the same core tools as the desktop app. Refer to
Terminal Interface.

Compatibility Notes
• Browser clients. PAIR's local endpoints now follow each engine's CORS
policy instead of allowing every browser origin. A browser-based client may
need the engine configured to allow it — for Ollama, set OLLAMA_ORIGINS in
the engine's launch options.
• The macOS app is now NVIDIA PAIR. The new NVIDIA PAIR.app installs
beside the old PAIR.app, so remove the old one to keep just one copy. Your
settings, cluster membership, and downloaded models carry over.
• LM Studio installed by an earlier PAIR. It keeps working as before. PAIR
now removes only engines it has a record of installing, and earlier versions
kept no record, so uninstalling or resetting PAIR leaves that LM Studio in
place. You can remove it from ~/.lmstudio yourself if you no longer want it.

The Upgrade Guide walks through each of these.

Targeted Bug Fixes
• Uninstalling LM Studio from PAIR, or uninstalling PAIR with its data…
