NVIDIA recently launched a groundbreaking series of small language models designed to enhance the capabilities of digital humans. By integrating large-context and multi-modal models, these advancements enable digital assistants, avatars, and agents to provide more pertinent responses and leverage visual inputs for a more comprehensive understanding. These models are part of NVIDIA's Avatar Cloud Engine (ACE), a suite of pioneering digital human technologies.
For digital humans to deliver enriched interactions, they need to process vast world contexts akin to human comprehension. One significant addition is the NVIDIA Nemovision-4B-Instruct model, a small, multi-modal model enabling digital entities to interpret visual imagery both in real-world scenarios and desktop environments, outputting relevant and informed responses.
"These models tap into the latest NVIDIA VILA and NeMo frameworks, optimizing for a variety of NVIDIA RTX GPUs while preserving the essential accuracy required by developers," remarked a spokesperson from NVIDIA.
Through distilling, pruning, and quantizing techniques, NVIDIA ensures that their multi-modal models remain performant yet efficient, serving as a foundation for agentic workflows. This technology empowers digital humans to execute tasks with minimal to no human intervention, paving the way for autonomous agents.
NVIDIA's new family of large-context small language models is designed to process substantial data inputs, understanding complex commands seamlessly. This includes the Mistral-NeMo-Minitron-128k-Instruct model family, featuring versions with 8B, 4B, and 2B parameters. These models allow configurations optimizing between speed, memory usage, and precision, tailored for NVIDIA RTX AI PCs.
"Solving intricate problems necessitates robust models capable of handling extensive data sets, thereby enhancing response accuracy and reducing the need for segmentation," the company's press release notes.
Achieving authenticity in digital human interactions is pivotal, necessitating realistic facial animations. The NVIDIA Audio2Face 3D NIM microservice utilizes real-time audio for synchronized lip-sync and facial expressions, now available as an intuitive, downloadable container. This tool enhances customization, featuring the inference model used for the "James" digital human.
The deployment of intelligent digital humans involves orchestrating animation, intelligence, and speech AI models efficiently. NVIDIA responds to this complexity with new SDK plugins and samples, facilitating on-device workflows. These resources include NVIDIA Riva for speech-to-text conversion, a Retrieval Augmented Generation demo, and an Unreal Engine 5 sample application.
"Our In-Game Inference SDK, currently in beta, simplifies AI integration. It automates model and dependency management, abstracts library details, and facilitates hybrid AI for seamless transitions between local and cloud AI execution," said an NVIDIA developer.
Tech enthusiasts can explore these SDK plugins and samples on the NVIDIA Developer platform.
