Spatius is next-generation real-time digital human infrastructure that enables AI to communicate through natural, expressive digital characters rather than text and voice alone. Companies can use Spatius across AI education, recruiting interviews, customer service, smart terminals, and companion products to create more engaging and lifelike user experiences.

Powered by its self-developed cloud-edge 3DGS technology, Spatius addresses visual quality, deployability, and cost at the same time. The product runs across web, mobile, and intelligent hardware, remains stable on constrained networks and a wide range of devices, and supports long-duration, high-concurrency interactions at predictable costs.

Spatius currently serves TAL Education and other leading customers in the education, recruiting, smart devices , and AI companion sectors. These products have reached millions of end users and supported tens of millions of digital human conversations, helping customers take real-time digital humans from demos into long-term, large-scale production.

Spatius features and specs

  • Photorealistic Real-Time Digital Humans
    Bring AI conversations to life with natural lip synchronization, facial expressions, and lifelike 3D characters. Spatius turns generated speech into responsive digital human animation in real time.
  • Cloud-Edge 3DGS Architecture
    Spatius combines lightweight cloud-based motion generation with on-device 3D Gaussian Splatting rendering. This architecture delivers high visual quality without continuously streaming rendered video from cloud GPUs.
  • Stable on Low-Bandwidth Networks
    Instead of transmitting a heavy video stream, Spatius sends lightweight motion data to the client device. This enables stable interactions on constrained, shared, or variable networks and helps prevent frozen or degraded avatar video.
  • Cross-Platform SDKs
    Deploy digital humans across web, iOS, Android, smart terminals, and intelligent hardware. Spatius supports modern browser and native rendering technologies, including WebGL/WebGPU, Metal, and Vulkan.
  • Built for Long-Running, High-Concurrency Use
    Spatius is designed for extended conversations and large-scale production deployments. Its edge-rendering architecture reduces dependence on cloud GPU capacity, enabling predictable costs as usage and concurrency grow.
  • Flexible AI Integration and Custom Avatars
    Connect Spatius to your preferred ASR, LLM, TTS, and real-time communication stack through standard audio-streaming interfaces. Teams can choose ready-made characters or deploy custom-branded 3DGS avatars for their own products.

Questions & Answers

As answered by people managing Spatius and InterviewFox.

What makes your product unique?

Spatius's answer

Spatius combines photorealistic 3D Gaussian Splatting avatars with a cloud-edge rendering architecture built specifically for real-time AI interaction. Instead of rendering every frame on cloud GPUs and streaming it as video, Spatius sends lightweight motion data to the userโ€™s device, where the avatar is rendered locally.

This approach addresses visual quality, network reliability, device coverage, and operating cost at the same time. It allows digital humans to remain responsive during long conversations, work across web, mobile, and intelligent hardware, and scale to high-concurrency production environments.

How would you describe the primary audience of your product?

Spatius's answer

Spatius is built for companies and developers creating AI products that benefit from natural, face-to-face interaction. Its primary users include teams working in AI education, recruiting and interviews, customer service, smart terminals, digital assistants, intelligent devices, and AI companion products.

It is especially well suited to organizations that require long-duration conversations, high concurrency, cross-platform deployment, custom-branded characters, or reliable operation on constrained networks and hardware.

What's the story behind your product?

Spatius's answer

Spatius was created to close the gap between digital human demonstrations and real-world deployment. Many avatar technologies can produce an impressive short demo, but become difficult or expensive to operate when conversations last longer, user numbers grow, or products must run across diverse devices and network environments.

The Spatius team developed its own cloud-edge 3DGS technology to solve these production challenges together. Today, Spatius helps companies turn AI into a more natural and expressive presence, bringing real-time digital humans into education, recruiting, smart devices, customer-facing terminals, and companion applications.

Which are the primary technologies used for building your product?

Spatius's answer

Spatius is primarily built on proprietary 3D Gaussian Splatting technology and a cloud-edge rendering architecture.

Its cloud-based Motion Server converts generated speech into lightweight facial and motion data, while the AvatarKit SDK renders and animates the 3DGS character locally on the client device. Platform technologies include WebGL and WebGPU for web applications, Metal for iOS, and Vulkan for Android. Spatius can receive real-time audio through technologies such as WebSocket, WebRTC, LiveKit, and Agora, and can integrate with third-party ASR, LLM, and TTS providers.

Who are some of the biggest customers of your product?

Spatius's answer

TAL Education is one of Spatiusโ€™s leading customers. Spatius also works with established companies across education, recruiting, smart devices, and AI companion products.

Products powered by Spatius have reached millions of end users and supported tens of millions of digital human conversations, demonstrating the platformโ€™s ability to operate in long-term, large-scale production environments.
