FlashDecoder: Real-Time Latent-to-Pixel Streaming Decoder with Transformers
Real-time video generation demands fast decoding as much as fast denoising, yet current latent video diffusion models rely on 3D convolutional decoders that are slow and memory-intensive at high resolutions or for long video. We introduce FlashDecoder, a fast, memory-efficient pu…
