Built for Low-Latency Interaction

Traditional video generation takes minutes. WaveSpeed Real-Time architecture is built to deliver frames in milliseconds.

Streaming Inference

Unlike batch processing, WaveSpeed's real-time API supports token-streaming. Video frames are returned as soon as they are generated, rather than waiting for the full clip to render, enabling instant playback start for interactive experiences.

ParaAttention Acceleration

Our proprietary ParaAttention technology optimizes the attention mechanisms within Transformer models, significantly reducing the computational overhead required for each frame. This keeps latency low even as scene complexity and sequence length increase.

WebSocket & WebRTC Support

Maintain persistent connections for bi-directional data flow. Stream audio or text inputs up and receive video frames down instantly over WebSocket or WebRTC, eliminating HTTP handshake overhead for continuous interactions.

Interactive Video Applications

Real-time generation unlocks use cases that were previously impossible with offline rendering.

Interactive Digital Humans

AI Customer Support

< 500ms latency. The avatar must respond to user voice queries instantly to maintain natural conversation flow. End-to-end streaming processes audio input and streams back lip-synced video frames via WebRTC.

Live Translation

Synchronized dubbing for live speakers. Video-to-video models modify incoming video streams frame-by-frame, adjusting lip movements and language in real time with negligible delay.

Gaming & Entertainment

Dynamic NPCs

On-demand animation for non-player characters. Generate short, reactive video clips with unique facial expressions and dialogue based on player actions using a low-latency API.

Personalized Live Streams

Dynamic overlays and shout-out clips generated in real time for specific viewers. Parallel generation handles thousands of concurrent requests for personalized assets during a broadcast.

Frequently Asked Questions

What counts as "Real Time" video generation?

We define Real Time as a generation process where the "Time to First Frame" (TTFF) is sufficiently low (typically under 500ms) to support interactive, conversational use cases without noticeable lag.

How does quality compare to offline generation?

To achieve sub-second speeds, real-time models often use distilled or optimized versions of larger models (like FLUX-schnell or distilled Wan). While extremely high quality, they prioritize speed and temporal consistency over the ultra-high detail of offline rendering.

Do you support WebRTC?

Yes. We provide WebRTC endpoints for developers building conversational AI agents. This allows for the lowest possible latency networking between your client and our GPU clusters.

What is the cost model for real-time?

Real-time services are typically billed by stream duration (minutes) rather than per-generation. This accounts for the continuous GPU reservation required to maintain the low-latency session.

Can I run this on my own servers?

We offer on-premise deployment options for enterprise clients who require edge computing capabilities to further reduce network latency or adhere to strict data sovereignty laws.

What models are optimized for real-time?

Currently, we support optimized versions of Stable Video Diffusion, AnimateDiff, and specialized Talking Head models designed specifically for real-time inference.
