Build a visual reference set
Choose images that are necessary for the scene. Describe the character, setting and action separately so that each reference has a clear purpose. Avoid mixing incompatible angles and styles without explaining them in your prompt.
Compare versions on one scene
Keep the prompt, references and duration the same when comparing Standard and Pro. Review detail, movement and adherence to your description. Current rates appear alongside available versions rather than being fixed in the article.
How to integrate the API
To integrate the Kling O3 API, select the exact version and settings in the playground. The generated cURL includes the endpoint, request fields and required Bearer authorization type. Move the request into your server code; keep secret keys out of the browser. References use service-accessible URLs rather than local file paths.
Pricing and generation budget
Kling O3 Standard and Pro have different rates. Keep duration, scene and inputs identical when estimating a budget. Also consider how many alternatives you need to find suitable motion: one clip’s cost and a finished scene’s cost can differ.
Comparing versions and workflows
Compare Standard and Pro on character, object and composition consistency. O1 Frames serves tasks with a specified ending image; Motion Control follows a driving video. Match the family to your source materials and the control your scene requires.
