About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Use kling-v1 with model, prompt and mode at /v1/videos. Choose std or pro and describe the shot in a prompt of up to 500 characters. The request exposes five- or ten-second duration, aspect\_ratio, model\_name, cfg\_scale and a negative\_prompt of up to 200 characters.

Use the available prompt space for the dominant subject, one action, setting and camera direction. Keep details that determine the composition ahead of decorative language. The cfg\_scale control accepts values from 0 to 1; retain the chosen setting with the brief when comparing a later variation.

Follow the original request ID instead of creating a second operation to check progress. The result uses data.task\_status and data.task\_result.videos\[\].url, with succeed marking completion. Save every completed video and its full response, then inspect the whole shot against the prompt.

### Pricing

##### How the final charge is calculated

The displayed rates estimate the cost before generation. The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity.

Tariff references do not add request options. Supported parameters are listed for the selected method.

Fast mode

Not specified When fast mode is selected

Flex mode

Not specified When flex mode is selected

Maximum reasoning effort

Not specified When maximum reasoning effort uses the default adjustment

#### Estimated rates for comparison

#### Prices by configuration

Match each charge to the conditions shown. Use one rate for each set of alternative configurations.

| Configuration | Rate schedule | Forecast quantity | Charge |
| --- | --- | --- | --- |
| ConfigurationBase token rates | Rate scheduleBase rate | Forecast quantity— | Charge Input · Input tokens · Estimate for comparison only **—** / 1K tokens Output · Output tokens · Estimate for comparison only **—** / 1K tokens Input · Cache read · Estimate for comparison only **—** / 1K tokens Input · Cache write · Estimate for comparison only **—** / 1K tokens Input · Cache write, 1 hour · Estimate for comparison only **—** / 1K tokens |
| ConfigurationEstimated generation cost | Rate schedule— | Forecast quantityone generation estimate | Charge Output · Estimated generation cost · Estimate for comparison only **$6** estimate before generation This estimate is not an additional charge or a fixed rate for the completed generation. |

Ailoot reserves an estimated amount before a request. After the result, it settles the final charge from measured usage. Streaming settlement uses the final usage record. [How reservation and settlement work →](https://ailoot.ai/docs/en/billing/reserve/)
