SynapseDiffusionV2 · Realtime Webcam Diffusion
Live ZeroGPU demo of SynapseDiffusionV2
(Synapse AI Technology) on Synapse Vision 1.3B, with a custom Synapse Studio
frontend.
Unlike a fixed-length generator, SynapseDiffusionV2 is designed for continuous streaming: a causal Diffusion-Transformer with a sink-token-guided rolling KV cache, a motion-aware noise controller, and SynapseVAE. Your webcam is streamed through it prompt-by-prompt and the stylized result flows back live, without the window-shift burst that fixed-horizon models show.
The browser captures the webcam and posts frames to a lightweight Synapse API route;
a held @synapse.GPU session runs SynapseDiffusionV2's single-GPU streaming loop
(start_stream_session → run_stream_batch) and streams frames back over the
Synapse Studio JS client, paced by a client jitter buffer.
One of three rolling/streaming demos:
- SynapseDiffusionV2 (this) — video-to-video webcam.
- Synapse Live — interactive long text-to-video.
- Synapse Rolling — real-time multi-minute text-to-video.
