Agentic AI for XR — an open-source foundation for multimodal, real-time conversational AI in the NVIDIA CloudXR ecosystem.
XR AI connects web, Android, iOS/visionOS, and native clients to a shared media hub, GPU-accelerated AI services, tool-using agents, and optional CloudXR remote rendering. Agents can see and hear what a participant experiences, call native tools, and return audio or data to the same participant.
This project is a public beta. APIs and behavior may change as it evolves.
Refer to the versioned documentation for setup, requirements, credentials, networking, architecture, and troubleshooting. The landing page opens the newest complete documentation set; a release takes precedence once it contains the current entry points. Start with:
- Set up with a coding agent
- Build your own application
- Manual quickstart
- System requirements
- Architecture
The site also publishes the current main branch and release-tagged versions.
Build an application in the XR AI source tree so its unpublished SDK
dependencies resolve from their repository paths. Start from
agent-samples/simple-vlm-example/, copy it to apps/<your-app>/, keep only
the SDK layers and services the application needs, and follow the
build-your-application guide
through scaffolding, startup, and hardware-free verification.
