Kandinsky 6.0 Video is an MIT-licensed model that generates five-second clips with synchronised 44 kHz audio and lip-sync in one pass. Confirm the model card.

A 10 October open-model roundup highlighted a theme of the week: joint audio-video generation. New models create picture and sound together, instead of producing silent video and adding sound in a separate step.

## What is new

Kandinsky Lab open-sourced Kandinsky 6.0 Video under the MIT licence. It comes in a 29-billion-parameter Pro version and a 3-billion-parameter Lite version, generating five-second clips with synchronised 44 kHz audio, including lip-sync, in one pass. It supports text-to-audio-video and image-to-audio-video modes, and a separate super-resolution plug-in raises output to Full HD. Tencent Hunyuan, with Fudan and Zhejiang universities, released Prism, an MIT-licensed framework for natively training joint video-audio models at 2K. It is described as a research preview for heavy GPUs. On the efficiency side, the same roundup notes FastH3 Trim for running MiniMax H3 video on 8 GB graphics cards.

> These specifications come from a single 10 October aggregator roundup. Confirm licence terms, clip length, and hardware requirements on the model cards before relying on them.

## Commercial models are moving the same way

Wan 3.0 generates dialogue, music, ambience, and effects alongside the picture. FLUX 3 Video includes native audio. Kling's upcoming release is announced with stereo sound. Joint generation has gone from a differentiator to something buyers expect.

## Why editors should care

When sound and image are produced together, footsteps land on the right frames and mouths match words without a separate sync pass. For missing B-roll, an atmospheric clip can arrive with its ambience already in place. For dialogue, lip-sync from the model can reduce repair work, though it still needs a listen.

## What an open model is worth

An MIT licence allows commercial use, local running, and fine-tuning, which suits confidential projects and studios that want control over versions. The Lite model's 3-billion-parameter size is in the range that desktop and laptop setups can plausibly target. Nobody should assume performance on specific hardware without testing. Five-second clips are short, so these are building blocks, not scenes.

## Limits

Open models often trail commercial leaders on the longest, highest-resolution output. Joint models can make it harder to isolate or replace one track. Check that you can separate dialogue from music and effects when the mix needs it.

## What to watch

Whether open models gain longer durations, and whether separate stems for dialogue, effects, and music become a standard output. Editors need the stems for mixing.
