02
kling-o3/pro
A higher-fidelity Kling O3 option for production previews, detailed motion, and reference-guided scenes that need stronger visual quality.

Key Features of Affordable Kling O3 API
Generate prompt-led, image-guided, and reference-driven AI videos through one cost-aware PoYo model page.
01
Text-to-Video for Fast Concept Clips
Start with a prompt and choose a Kling O3 model for short cinematic clips. PoYo supports 3-15 second duration control, aspect ratios for landscape, portrait, and square output, and an optional sound toggle for single-shot requests.
- Generate from prompt only
- Choose 3-15 second clips
- Use 16:9, 9:16, or 1:1
02
Image-to-Video With Start and End Frames
Animate one uploaded image or guide a transition with two image inputs. PoYo keeps image_urls limited to two images, matching the exposed API surface for first-frame and end-frame video generation.
- Animate a starting image
- Guide with an end frame
- Keep image inputs predictable
03
Reference-to-Video for Consistent Visual Direction
Add up to four reference images to guide style, subject, or scene direction. When reference_image_urls are present, PoYo uses the reference-to-video workflow and keeps Kling elements scoped to that reference-driven mode.
- Use up to four references
- Guide subjects and style
- Apply Kling elements in reference mode
04
4K Output for High-Detail Video Workflows
Use kling-o3/4K when your workflow needs sharper detail and a premium output tier. The 4K model keeps the same text, image, and reference input modes while charging a fixed 50 credits per second.
- Select the 4K model
- Use fixed per-second pricing
- Keep the same PoYo controls
What Can You Build With Kling O3 API?

Reference-Guided Creative Direction
Use reference images and Kling elements to guide recurring subjects, visual style, or scene mood in reference-to-video workflows.
04
Social Video Production

Frequently Asked Questions about Kling O3 API
What Kling O3 models are available on PoYo?
PoYo exposes three public Kling O3 models: kling-o3/standard, kling-o3/pro, and kling-o3/4K. Standard is the lower-cost option, Pro is the higher-fidelity option, and 4K is the premium high-detail option.
Which generation mode runs when I send images?
If reference_image_urls are present, the request uses reference-to-video. If no reference images are present but image_urls includes an image, the request uses image-to-video. Prompt-only requests use text-to-video.
What input limits should I follow?
duration must be an integer from 3 to 15 seconds. image_urls supports up to 2 images, reference_image_urls supports up to 4 images, and aspect_ratio must be 16:9, 9:16, or 1:1.
How does multi-shot generation work?
When multi_shots is enabled, send multi_prompt instead of relying on a single prompt. PoYo requires sound to be enabled for this mode, and the total clip duration still needs to stay within 3-15 seconds.
When can I use Kling elements?
kling_elements are available for reference-to-video requests. Add reference_image_urls first, then use Kling elements to guide subjects or visual consistency in that reference-driven workflow.
How much does Kling O3 cost on PoYo?
Standard costs 10 credits/s without audio or 13 credits/s with audio. Pro costs 13 credits/s without audio or 16 credits/s with audio. 4K costs 50 credits/s ($0.25/s).
