Key Benefits of Omniverse ACE

Simple to Build

Enjoy realistic, advanced Avatar development without the need for specialized expertise, equipment, or manually intensive workflows. With cloud-based AI models, toolsets, and pre-built application frameworks like Tokkio, Omniverse ACE enables you to build realistic Avatars quickly.

Realistic Results

Bring your avatars to life using rich software tools and APIs, including Omniverse Audio2Face for simplified character animation, Conversational AI solutions like NVIDIA Riva for natural speech-based interaction, NVIDIA Metropolis for computer vision, and NVIDIA Merlin for high-performance recommender systems.

Flexible Deployment

Build, configure, and deploy your avatar application across any engine in any public or private cloud. Whether you have real-time or offline requirements, Omniverse ACE enables you to develop and deploy your Avatar to suit your needs.

Real-Time AI Development

Omniverse ACE is built on NVIDIA’s Unified Compute Framework (UCF), enabling developers to seamlessly integrate NVIDIA’s suite of avatar technologies into their applications.

Application Frameworks

Developers can leverage Omniverse ACE to build their own domain-specific avatar solutions, or use NVIDIA’s suite of application frameworks for next-generation web conferencing, intelligent AI-service agents, and more.


Project Tokkio is an application built with Omniverse ACE - bringing AI-powered customer service to retail stores, quick-service restaurants, and even the web. It comes to life using NVIDIA AI models and technology like NVIDIA Metropolis, NVIDIA Riva, and NVIDIA NeMO. Since it runs on NVIDIA’s unified computing framework (UCF), NVIDIA Tokkio can scale out from the cloud and go wherever customers need helpful avatars with responsive and natural behavior.

Animation AI

Omniverse Audio2Face beta simplifies animation of a 3D character to match any voice-over track, whether you’re animating characters for a game, film, real-time digital assistants, or just for fun. You can use the app for interactive real-time applications or as a traditional facial animation authoring tool. Run the results live or bake them out, it’s up to you.

QSR Customer Service

See customers interact with Project Tokkio, an Omniverse ACE-powered conversational-AI kiosk. This reference application leverages NVIDIA Metropolis vision AI and NVIDIA Riva speech AI technology to communicate with the user. It uses NVIDIA’s NeMo Megatron-Turing 530B, a state-of-the-art language model for understanding intent, and NVIDIA Merlin to make meaningful recommendations. The 3D avatar is animated and visualized with Omniverse to deliver a visually stunning customer service experience—all in real time.

Natural, Expert Q&A Assistant

In this demo, we see one example of Project Tokkio - a “talking kiosk” reference application featuring a photorealistic, life-like autonomous avatar responding to challenging domain-specific questions. The avatar, built in Omniverse, is a reference application that leverages several key NVIDIA technologies, including NVIDIA Riva for speech AI, NVIDIA’s NeMo Megatron Megatron-Turing 530B large language model, and a combination of NVIDIA Omniverse animation systems for facial and body animation.
