Seedance 2.5 draft mode in API: set draft:true for a 480p preview billed at 480p, then call text_to_video with draftTaskId within 7 days to enhance to 1080p at the 1080p rate. Kling 4.0 is not in this catalogue yet. Comparison: Seedance 2.5 1080p via Runway ($40.80/min) is above AA's listed $34.12/min creator-API price (C3-B369-01), showing host markups/differences.
