Which AI video model generates native audio with the video?
Veo is the only covered model with native audio generation; the rest produce silent video that needs separate audio.
Short answer
Veo (Google Veo 3) is the only covered AI video model with native audio generation — it produces synchronized sound with the video. Every other model outputs silent video that needs a separate audio pass. If native audio matters to your workflow, Veo is currently the only documented option.
Native audio is a clear-cut capability question rather than a consistency one: Veo generates sound with the clip, the rest do not. That makes Veo the default for talking-head or ambient-sound work where syncing audio separately is friction. Its documented weak spots are elsewhere — long multi-instruction prompts, where camera directions get dropped — so pick Veo for audio, then keep prompts short to stay inside its reliable zone.

Which model holds…
Pick by the thing that has to stay consistent
Holds a consistent face across cuts
Runway Gen-4
Runway Gen-4 Scenes mode is the only documented model built specifically to hold a character across multiple cuts; others drift after a few cuts.
Holds readable on-screen text
No model reliably does
Text rendering is a documented failure mode for every covered model — all garble past roughly six characters. Add text in post instead of relying on the model.
Holds correct hands in close-up
No model reliably does
Hand-anatomy failure is documented across every model. Frame hands away from camera or expect to re-roll; no model has solved close-up finger topology.
Holds cinematic lighting in a single take
Luma Ray-2
Luma Ray-2 documents the fewest lighting-related failures and leads on photoreal cinematic light for mood-led single-shot work.
Holds long, multi-instruction prompts
No model reliably does
Every model documents an instruction-drop / prompt-adherence failure that worsens as prompt length grows. Front-load must-haves and keep prompts short.
