Move from Kling 3 to Wan 3.0: one id change and the price gap

Replacing kling-3 with wan-3.0 in a Sume request changes a 10-second clip from $2.10 (sound on) or $1.40 (silent) to $1.25 at 720p, and raises the length ceiling from 15 to 30 seconds. Alibaba lists wan3.0-video with an audio toggle and 480P, 720P and 1080P output (read 2026-10-08); check that the audio behavior of the Sume id fits your clip before you move.

Same clip, both ids

The diff

Your request body keeps its prompt and duration. Remove nothing you do not need to; add resolution to control cost, since Wan 3.0 is priced by it.

-  "model": "kling-3",
+  "model": "wan-3.0",
   "prompt": "A runner laces shoes at dawn",
   "duration": 10,
-  "generate_audio": true
+  "resolution": "720p"

Before you flip a production flag

Run your ten most important prompts on both ids and compare the clips yourself. Price and limits are facts in the catalog; how a model handles your brand's subject is not.

Over a month

A hundred 10-second clips a month is $210.00 on kling-3 with sound and $125.00 on wan-3.0 at 720p. The difference is $85.00, which is the budget to spend on a comparison run before you commit.

The move also changes the pricing lever. Kling 3 is priced by audio on or off and has no resolution input here; Wan 3.0 is priced by resolution and doubles from 720p to 1080p. Decide the resolution you will publish at before you compare totals.

Sume reserves the full price at submit, so the number in the table is also the amount that must be free in the balance when you send the request. If it is not, the call fails with 402 insufficient_credits before any provider work starts.
