Kling 4.0 Launches on Runware with 30-Second 1080p Native Audio Video

Runware announced on October 26, 2026 that Kling 4.0 is now available on its platform. Kling 4.0, an AI video generation model developed by Kuaishou, can produce videos up to 30 seconds long at 1080p resolution with native audio.

The model supports multi-keyframe control, including first, middle, and last frames. Users can also provide reference images, reference videos, and elements as inputs, with up to 15 inputs allowed per request for more precise generation.

Runware is a cloud platform for AI model hosting and inference. Developers can now access Kling 4.0 through Runware's APIs. Creator guides were also shared in the announcement to help users get more out of the model.
