Kling 4.0 Flash is the lightweight video generation model in Kuaishou's Kling 4.0 series, built for high-frequency creative work with a focus on generation speed and cost effectiveness. It supports text-to-video, image-to-video (first frame) and omnipotent reference-to-video: a single task can combine up to 15 assets (up to 10 images, 5 videos and subjects), reliably reusing characters, product appearance and motion/camera work, and it can also make local edits to the subject, background and style of existing videos; prompts can be up to 26,000 English characters. Each generation runs 3–20 seconds, outputs 720p, supports 21:9 / 16:9 / 1:1 / 9:16 and adaptive aspect ratios, and produces audio and video together. It suits high-volume social media short video production, e-commerce asset creation and rapid creative validation.
