Paper page – Wan-Streamer v0.1: End-to-end Real-time Interactive Foundation Models

Comparison with other interactive models / systems:

The two groups measure different things. The top group is full end-to-end interaction loops — they perceive the user and produce a response; only Wan Streamer also outputs video. The bottom group is avatar / audio-visual renderers timed at the rendering stage only: their latency excludes the external language model, ASR, and TTS they depend on, so their true user-visible latency is higher than shown. Wan Streamer is the only end-to-end model that outputs synchronized audio + video, and it does so under 0.6 s. Numbers are the closest publicly reported figures and mix measurement boundaries; see the paper for exact definitions.

Capability coverage across representative systems. Full-duplex means the system keeps perceiving while it generates — understanding and responding at the same time. Wan Streamer is the only model that perceives video, outputs synchronized video, runs full-duplex, is end-to-end, and responds within a second; every other system covers only part of this. “~” marks partial support or a figure that is not publicly disclosed.
