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.

ImageOptim API features and specs

  • Efficient Compression
    The ImageOptim API provides high-quality image compression, which reduces file sizes without significantly affecting visual quality. This results in faster loading times for websites and applications.
  • Support for Multiple Formats
    The API supports a variety of image formats including JPEG, PNG, and GIF, allowing for broad use across different platforms and projects.
  • Optimization Options
    Users can customize the optimization process, adjusting quality settings and choosing between lossless and lossy compression according to their needs.
  • Integration Capability
    The API can be easily integrated into build systems and CI/CD pipelines, which helps automate the optimization process for developers.
  • Preservation of Metadata
    The API provides the option to preserve or strip metadata from images, offering flexibility according to privacy and SEO considerations.

Possible disadvantages of ImageOptim API

  • Cost
    The ImageOptim API is a paid service, which may not be cost-effective for smaller projects or those with limited budgets.
  • Dependency on External Service
    Using an external API means that your service is dependent on the uptime and reliability of ImageOptim, which could be a risk if their service experiences downtime.
  • Limited Control Over Process
    While the API offers some customization, users might have limited control compared to local optimization tools where they can deeply tweak optimizations and algorithms.
  • Privacy Concerns
    Sending images to an external service for processing could raise privacy concerns, especially with sensitive or proprietary images that might require local processing for security reasons.

Questions & Answers

As answered by people managing Spatius and ImageOptim API.

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.
