Model specifications and parameters
Fields are shown for this model's connected endpoint, not one generic form for every model.
| Parameter / field | Current range | Description |
|---|---|---|
| duration | 4–15 s / -1 | Omitted API duration defaults to 5 seconds. |
| resolution | 480p / 720p / 1080p / 4k | Output resolution varies by model. |
| ratio | 21:9 / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 / adaptive | A fixed ratio maps to valid dimensions; smart mode lets the model decide. |
| output_format | mp4 | Output video container format. |
| generate_audio | true / false | Available only when this model supports audio output. |
| watermark | true / false | Whether this model lets you control the output watermark. |
| content.role=first_frame | Optional | Optional reference image; first-frame rules vary by model. |
| content.role=last_frame | Optional; requires a first frame | First and last frames are separate image inputs. Matching ratios work best; the last frame follows the first frame's canvas. |
| mode | omni_reference / omni_edit / omni_extend | The web UI offers reference, edit and extend according to this model. LINK42 converts or removes its mode field before the provider call. |
| content.role=reference_image | 0–9 | Omni reference images and first/last frames are mutually exclusive. |
| content.role=reference_video | 0–3 | Reference videos may be up to 15 seconds. Video input selects its own price tier. |
| content.role=reference_audio | 0–3 | Reference audio may be up to 15 seconds and needs an image or video too. |
| Web batch count | 1–8 | The experience center submits up to eight separately billed tasks, not one upstream n parameter. |
Provider limits and LINK42 web-test limits may differ. LINK42's current quote and actual settlement govern price; external docs are provided to verify model capabilities.

Are playground tests billed?
Yes. Tests use the signed-in account's balance. The estimated hold is shown before submission, and the final amount is calculated from actual usage and effective pricing.
What happens if a test fails or stops?
Requests rejected before generation have no model usage. Failures, cancellations and interrupted streams are settled or released by the shared ledger. Check the run record for any billable usage already produced.
Where can I see results and charges?
Recent results and actual charges are available in the test history. Open the usage record using its request ID. Download large results promptly.
