What does Spatius.ai do?

Spatius.ai offers a unique infrastructure for creating and deploying real-time AI avatars. Instead of traditional cloud streaming, it uses a cloud-edge hybrid approach, where audio feature extraction happens in the cloud, but the actual 3D Gaussian Splatting rendering occurs on the edge. This means you can get highly realistic, lip-synced digital humans that perform well even on weaker networks and less powerful devices.

What makes Spatius.ai stand out is its focus on efficiency and accessibility. It can run 1080p at 25fps on entry-level chipsets without needing dedicated GPUs, which is a big deal for keeping costs down and expanding deployment options. The system accepts audio streams via standard protocols like LiveKit WebRTC or WebSockets, directly translating them into facial animations without extra steps.

This technology is perfect for developers and businesses looking to integrate stable, voice-driven avatars into various applications. Think language learning apps, HR tech for interviewers, mental health companions, in-vehicle systems, or even AI hardware. It also supports custom avatar integration, allowing users to deploy their own trained 3DGS models alongside stock options.
