API Overview

Kling is a video generation large model developed by Kuaishou's large model team. As the world's first truly user-available video generation large model, Kling has gained enthusiastic popularity among users worldwide due to its unparalleled video generation effects.

The latest version of Kling 2.1 features higher motion quality, more beautiful and dynamic video effects, and better instruction response capabilities. In addition, during the 2.0 model iteration, Kling AI officially released a new interactive concept for AI video generation called Multi-modal visual language (MVL), enabling users to combine multi-modal information such as image references and video clips to transform their creative ideas in their minds into vivid videos.

This model is known for its extremely high realism and detail expression, especially in aspects such as lighting, materials, and textures[5], allowing users to easily and efficiently complete artistic video creation. As the first domestic AI video generation model comparable to Sora, Kling is hailed as a shining example of domestic products.

Note: If using the base64 method, please make sure to pass the Base64 encoded string directly without adding the data:image prefix. Supported image formats are .jpg/.jpeg/.png, file size must not exceed 10MB, image resolution must be at least 300*300px, and the aspect ratio should be between 1:2.5 and 2.5:1. Example Value:`iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==` up_expansion_rationumber Required Expand Upwards Calculated based on a multiple of the original image height. Value range: [0,2]. The total area of the new image must not exceed 3 times that of the original image. For example, if the original image height is 20 and the current parameter value is 0.1, then the distance from the top edge of the original image to the top edge of the new image is 20 x 0.1 = 2. The area within this range is the expansion area. right_expansion_rationumber Required Expand to the right Calculated based on a multiple of the original image height. Value range: [0,2]. The total area of the new image must not exceed 3 times the original image. For example, if the original image height is 20 and the current parameter value is 0.2, then the distance from the bottom edge of the original image to the bottom edge of the new image is 20 x 0.2 = 4. The area within this range is the expansion area. left_expansion_rationumber Required Expand range to the left Calculated based on a multiple of the original image width. Value range: [0,2]. The total area of the new image must not exceed 3 times that of the original image. For example, if the original image width is 30 and the current parameter value is 0.3, then the distance from the left side of the original image to the left side of the new image is 30 x 0.3 = 9, and this area is the expansion range. down_expansion_rationumber Required Expand downward Calculated based on a multiple of the original image height. Value range: [0,2]. The total area of the new image must not exceed 3 times that of the original image. For example, if the original image height is 20 and the current parameter value is 0.2, then the distance from the bottom edge of the original image to the bottom edge of the new image is 20 x 0.2 = 4. The area within this range is the expansion area. promptstring Optional Positive text prompt ninteger Optional Number of images to generate
