The 13 models that generate sound

Veo 3.1, Veo 3.1 Fast, Grok Imagine Video, Seedance 2.0, Seedance 2.0 Fast, Seedance 2.0 Mini, Seedance 2.5, Vidu Q3 Pro, Vidu Q3 Turbo, PixVerse v6, PixVerse v5.6, LTX-2.5 Fast and P-Video all produce synchronized audio. The remaining nine — Wan 3.0, Wan 3.0 Prime, Hailuo 2.3, Hailuo 2.3 Fast, HappyHorse 1.0, HappyHorse 1.1, RunwayML Gen-4.5, RunwayML Aleph 2 and FLUX 3 Video — output silent video.

Not all generated audio is the same

Grok Imagine Video is the most ambitious, producing synchronized dialogue, sound effects and music in one pass, with normal, fun and custom creative modes. Veo 3.1 and Seedance 2.0 focus on coherent scene sound and score. PixVerse v6, Vidu Q3 and LTX-2.5 Fast generate mood-appropriate audio beds. P-Video and the Seedance family accept audio as an input, so you can drive motion from a track you supply rather than one the model invents.

When generated audio is not worth it

If you are scoring the piece properly, generated audio is a scratch track you will throw away — and you paid for it. For voiceover-led explainers, for licenced-music pieces, and for anything going into a professional mix, generate silent and do the sound in post. Use native audio when the clip ships as-is: social shorts, UGC-style ads, music visuals.

Audio-conditioned generation is different again

Supplying audio as an input is not the same as asking the model to invent audio. P-Video supports audio-conditioned generation up to 20 seconds, and Seedance 2.0 and 2.5 accept audio references. The result is motion that tracks the beat — which is the entire point for music visuals and dance content.
