}Kling 2.5 Turbo
Kling 2.5 Turbo. Cost-effective. Text-to-video and image-to-video, supports first & last frame. No native audio.
Pricing — per second of generated video, in tokens (USD at $0.02/token):
| resolution | tokens/s | USD/s |
|---|---|---|
| 720p | 1.89 | $0.038 |
| 1080p | 3.15 | $0.063 |
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.
Now served by Kling’s current API. Two changes came with that move: a first + last frame pair now requires resolution: 1080p (a 720p request carrying image_end_url is rejected up front rather than silently billed at 720p and produced at 1080p), and negative_prompt has been removed — the current API has no such field, so put negative descriptions in prompt.
⚠️ Note the direction: kling-2-6 has the same first+last-frame rule but locked to 720p instead. They are opposite.

Kling 2.5 Turbo. Cost-effective. Text-to-video and image-to-video, supports first & last frame. No native audio.
Pricing — per second of generated video:
- 720p — 1.89 tokens ($0.038)
- 1080p — 3.15 tokens ($0.063)
Model name. Must be kling-2-5-turbo on this page.
kling-2-5-turbo Text prompt describing the video.
First-frame image URL. If provided, runs image-to-video; otherwise text-to-video.
Last-frame image URL (first & last frame mode). ⚠️ Requires resolution: 1080p — Kling only produces 1080p when both frames are given, and this endpoint rejects a 720p request that carries a last frame.
Video duration in seconds. Only 5 or 10.
5, 10 Output resolution. 720p = Standard mode (std), 1080p = Professional mode (pro).
720p, 1080p Aspect ratio. Text-to-video only; ignored when image_url is provided.
16:9, 9:16, 1:1 Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.
