The models' case: best overall generation quality in 2026 — native synced audio/dialogue, strong physics and prompt adherence, image-to-video with reference images and scene extension. The models' main caveat: priciest mainstream option (~$0.40/sec with audio) with short clip lengths and conservative content filters that block a surprising amount of. The strongest alternative is Kling — High physical motion fidelity, camera trajectory control, 4K resolution, and robust lip-sync capabilities at a highly competitive per-second cost.
