Compare the Kling models
Each Kling model targets a different production need. Use this table to decide which route should own your workflow on EvoLink.
| Model | Best for | Modes | Editing | Duration | Entry pricing |
|---|---|---|---|---|---|
Kling 3.0 Standard | Reliable text-to-video and image-to-video generation for standard production workflows. | Text-to-video, image-to-video | No | 3-15 seconds | $0.075 - 0.150/s |
Kling O1 Unified | Combined generation and editing with consistent characters and scenes across clips. | Text, image, video, and subject inputs | Yes, instruction-based | 3-20 seconds | $0.111/s |
Kling O3 Advanced | Full multimodal control including reference-to-video, editing, and all standard modes. | Text-to-video, image-to-video, reference-to-video, video editing | Yes, reference and instruction-based | 3-15 seconds | $0.075 - 0.125/s |
Kling 3.0 Motion Control Motion | Transferring motion patterns from a reference video to a character image. | Motion transfer | No | 3-30 seconds | $0.113 - 0.151/s |
How to decide which Kling model to use
Follow these 4 rules to narrow down your choice.
Start with output type
Text-to-video, image-to-video, or reference-to-video — different Kling models support different input modes.
Then check editing needs
If you need to refine clips after generation — instruction-based editing or reference control — compare Kling O1 and O3.
Then check duration and cost
Longer clips cost more per second. Match your target duration to the model that supports it at the best price.
Finally, consider motion transfer
If your workflow requires transferring movement patterns from a reference clip to a character image, Kling 3.0 Motion Control is the dedicated route.
If you already know your task type, find the recommended starting point in the table below.
Choose a Kling model by workflow: generation, editing, multimodal, and motion transfer
Match your primary video task to the right Kling model.
| Your task | Recommended start | Good fit if... | Watch out for |
|---|---|---|---|
| Standard text-to-video or image-to-video | Kling 3.0 | You need reliable clip generation from text prompts or input images without editing complexity | No editing or reference-to-video support |
| Generation + editing in one engine | Kling O1 | Character consistency and instruction-based editing matter across multiple clips | Slightly higher cost than Kling 3.0 standard mode |
| Full multimodal control | Kling O3 | You need reference-to-video, video editing, and all standard modes in one model | Most capable but check per-second cost for your volume |
| Motion transfer from reference clip | Kling 3.0 Motion Control | You want to transfer movement from a reference video to a character image | Dedicated to motion transfer — not a general-purpose generation model |
Kling API workflows: text-to-video, image-to-video, editing, and motion transfer
See how Kling models fit into real video production pipelines and content workflows.
Text-to-video generation
For marketing clips, social media content, product demos, and explainer videos from text prompts. Start with Kling 3.0 for straightforward generation. If you need higher quality or longer clips, compare Kling O3.
Image-to-video animation
For animating product images, illustrations, or photos into short video clips. Kling 3.0 and O3 both support image-to-video. Choose O3 if you also need reference control or editing in the same workflow.
Video editing and refinement
For instruction-based editing, scene refinement, and character-consistent clip iteration. Kling O1 brings generation and editing into one engine. Kling O3 adds reference-to-video on top of editing support.
Motion transfer and animation
For transferring dance moves, gestures, or motion patterns from a reference video to a character image. Kling 3.0 Motion Control is the dedicated route for this workflow, supporting clips up to 30 seconds.

Access Kling models through one EvoLink API
All Kling models are available through a single EvoLink API key. Switch between Kling 3.0, O1, O3, and Motion Control by changing the model parameter — no separate accounts or keys needed.
Switch model="kling-v3" to model="kling-o3" without rebuilding your integration.How to think about Kling video generation cost: quality, duration, and volume
Higher quality increases per-second cost
Advanced models like Kling O3 with reference-to-video and editing produce richer output but cost more per second. If your clips are short and quality matters most, the premium may be worth it. For bulk generation, start with Kling 3.0.
Longer clips multiply total cost
All Kling models use per-second billing. A 15-second clip costs 5x more than a 3-second clip on the same model. Estimate your target duration before choosing a route.
High-volume workflows need cost control
If you generate hundreds of clips per day, per-second cost compounds quickly. Test with Kling 3.0 standard mode first, then upgrade to O1 or O3 only for clips that need editing or reference control.
