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'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 user’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.

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.
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.
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.

Choose between Apache or Nginx as your web server and configure it to handle API requests. For Apache, use an .htaccess file in your project directory to enable clean URLs and route all traffic through your main PHP file. Nginx requires similar adjustments in its server block configuration. - Source: dev.to / 12 months ago

The license was notably used in web server software, such as in projects that led to the creation of the Apache HTTP Server. Its source disclosure requirement helped build trust among early developers, and community improvements drove rapid innovation during the early stages of the internet. - Source: dev.to / over 1 year ago
Enterprise Software Frameworks: Companies developing robust, scalable solutions now favor licenses that not only protect against unauthorized commercial exploitation but also encourage contributions. Just as the Apache HTTP Server has been a success story for open source, frameworks built on the HSQLDB License have gained traction for their fairness. - Source: dev.to / over 1 year ago
Web Servers and Infrastructure Projects: Projects like the widely used Apache HTTP Server emphasize stability and developer fairness. SISSL 1.1 has been utilized in similar infrastructure projects to provide legal certainty while preventing exploitation of contributions. - Source: dev.to / over 1 year ago
