What a Clip Actually Costs
Kling 2.5 Turbo Pro generates clips of 5 or 10 seconds. At 1080p, the per-clip cost on Opennan works out like this:
- 5 seconds: $0.273 on Opennan vs $0.35 at the official rate
- 10 seconds: $0.546 on Opennan vs $0.70 at the official rate
The 1080p Turbo Pro tier is the only tier shown in the Opennan price table for this model. No 720p or 480p option appears for this specific model in the evidence.
API Price Comparison
The table below shows only prices found in the evidence for Kling 2.5 Turbo Pro.
| Provider | Price per second | Resolution | Tier / condition |
|---|---|---|---|
| Opennan | $0.0546 | 1080p | Turbo Pro, pay-as-you-go |
| Official (Kling) | $0.07 | 1080p | Turbo Pro, maker's list price |
Opennan's pricing page states it never sells above the maker's list price and targets at least 10% below on most tiers.
What You Get for That Price
The Opennan model page shows the same model identifier, the same resolution, and the same length options as the official Turbo Pro tier. You call it by sending a POST request to https://api.opennan.com/v1/videos/generations with your key as a bearer token in the Authorization header and the request body as JSON.
The model accepts three input types:
- Text prompt, describes what happens in the clip (up to 4,000 characters)
- Start image, an HTTPS link; the video begins on that frame
- Reference images, a list of HTTPS links; keeps specific people or objects consistent across frames
Supported aspect ratios are 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and 9:21. Duration is either 5 or 10 seconds. The 10-second option adds $0.273 over the 5-second base cost.
Failed runs are refunded in full. The Opennan model page states explicitly: "failed: you are not charged." You pay only for completed outputs.
One API key covers all models on the platform, video, images, text, voice, music, sound effects, and 3D, so there is no separate account or credential to manage alongside this one.
Your First API Call
Send a POST to the generations endpoint with your key as a bearer token. The call returns a task ID immediately; poll the task endpoint until the status field reads succeeded or failed.
curl https://api.opennan.com/v1/videos/generations -H "Authorization: Bearer $OPENNAN_KEY" -H "Content-Type: application/json" -d '{"model":"kling-2-5-turbo-pro","prompt":"Rain on a neon street at night, slow push-in","duration":5,"quality":"1080p","aspect_ratio":"16:9"}'
Then retrieve the result:
curl https://api.opennan.com/v1/tasks/<task-id> -H "Authorization: Bearer $OPENNAN_KEY"
When status is succeeded, the video URL is in outputs[].url. A 401 means the key is missing or wrong; a 402 means the balance needs topping up; a 429 means you have sent too many requests and should wait before retrying.
How Kling 2.5 Turbo Pro Fits Alongside Other Models
If your project needs audio generated alongside the video, Veo 3.1 Fast on the same key supports an optional generate_audio parameter. It starts at $0.065/s for 720p (official $0.08/s, 18% below) and goes up to 4K. It also accepts distinct start and end frames, which is useful when you need precise in and out points. Audio adds $0.0325/s to the per-second rate on that model.
If you need longer clips, the Seedance 2.5 model supports durations from 4 to 15 seconds and accepts reference videos as inputs alongside reference images and start or end frames. Its cost starts at $0.2867/s at 480p, making it a higher-cost option suited to productions that need that degree of control over continuity and length.
Kling 2.5 Turbo Pro sits between those two: 1080p native resolution, reference-image support for consistent subjects, 5 or 10-second clips, and a per-second rate the evidence puts 22% below the official list.
FAQ
Is the output quality the same as going directly to Kling?
The Opennan model page shows the same model identifier, the same 1080p resolution tier, and the same length options as the official Turbo Pro listing. The page does not describe any difference in output. No independent quality comparison appears in the evidence.
Which aspect ratios are supported?
Seven ratios are accepted: 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and 9:21. Pass the value in the aspect_ratio field of your request. The default is 16:9.
Does Kling 2.5 Turbo Pro generate audio?
The parameter table on the Opennan model page for Kling 2.5 Turbo Pro does not list a generate_audio option. If audio is a requirement, Veo 3.1 Fast on the same platform supports that parameter.
What happens if a generation fails?
The Opennan model page states that a failed task is refunded in full: "failed: you are not charged." You pay only for completed results.
Can I call it from an AI agent or MCP client?
Yes. Add the MCP server at https://api.opennan.com/v1/mcp with your API key as a bearer token. Your AI then calls the generate_video tool with model set to "kling-2-5-turbo-pro". The same server exposes every other Opennan tool, so one setup covers video, images, voice, music, and more.
To try Kling 2.5 Turbo Pro without code first, the Opennan model page has a live form where you can enter a prompt and see the exact cost before running. The pricing page lists all 17 video models side by side so you can compare rates across the full catalog before deciding which fits your project.
