Kling 4.0AI video generator
One take up to 30 s at 1080p, first and last frames, 10 images and 5 clips — also edits clips. Pay only for the takes you keep — kill the rest for a full refund.
Kling 4.0 is Kling (Kuaishou)'s AI video model for text-to-video, image-to-video, reference-to-video, and clip editing. A take can run 3–30 seconds at up to 1080p, with first and last frames, up to 10 images and 5 clips as references, four aspect ratios, and native sound and dialogue generated with the picture.
Use it for ads, product films, social clips, and short scenes that need a locked start or end frame. Work in the web studio or from Claude, ChatGPT, and Cursor via Elyum's MCP server and REST API. Plans: Free (our algorithm may grant up to 100 credits once), Plus $9/mo, Pro $29/mo, Ultra $69/mo; credits can also be topped up.

Why Kling 4.0 is good
Every Kling 4.0 render comes back as a take you can judge. KEEP it and credits charge; KILL it and you get a full refund. Nobody else refunds bad generations.
One take runs 3–30 seconds at up to 1080p, with four aspect ratios. 1080p is 25 credits per second; 720p is 17 credits per second.
Set first and last frames, then add up to 10 images and 5 clips as references. Text-to-video, image-to-video, and reference-to-video all sit on the same model.
Kling 4.0 generates sound and dialogue with the video, so you are not stitching a silent clip to a separate audio pass for dialogue-led shots.
Kling 4.0 also edits clips on Elyum, so a shot you already have can go back through the same model instead of starting from a blank prompt.
Kept takes download full quality with no watermark. Commercial use is included. Elyum prices run about 20% under comparable platforms.
