If you want joint video and audio without a closed API, this is the open drop to try. Kandinsky Lab released Kandinsky 6.0 Video under MIT: a 29B Pro and a 3B Lite that render five-second clips with synchronised 44 kHz audio, including lip sync, from text or image.
Diffusers weights are on Hugging Face, and day-one packs land in ComfyUI and FastVideo. Treat Pro as a workstation job and Lite as the local test bed, then decide whether native sound-in-the-same-pass beats your current cut-and-dub stack.
