Waiting for Kling 4.0? Eight Sume video ids by 10-second price

While Kling 4.0 is only announced, the cheapest id to try on Sume (from an image you supply) is grok-imagine-video-1.5 at $0.125 for 10 seconds, and the most expensive of the eight below is seedance-2.5 at $5.78. kling-3 sits in the middle at $2.10 with sound. Price is the only ranking here: nobody can say from a table which clip will look right for your product.

Ten seconds, cheapest first

Each row is one 10-second request at the resolution shown, billed at the provider list price times 1.25.

Limits that matter before you pick

• grok-imagine-video-1.5 is image-to-video only, so it needs a first-frame image and takes 4 to 15 seconds. gemini-omni-flash-1.1 stops at 10 seconds and always generates audio.
• minimax-h3 and minimax-h3-max take 5 to 15 seconds.
• kling-3 takes 4 to 15 seconds; seedance-2.5 and wan-3.0 go to 30.

A way to choose

Run the same prompt on three ids at the cheapest setting, look at the three clips, and only then spend on the higher tier of the winner.

Reading the ladder

The spread is wide: the top row is 46 times the bottom one. That is why a cheap first pass matters. Ten Grok drafts cost $1.25, which is less than one 10-second kling-3 clip with sound at $2.10.

Resolution moves each row too. Wan 3.0 doubles from 720p to 1080p, MiniMax H3 Max doubles from 768p to 1080p, and Seedance 2.5 more than doubles. Rank by the resolution you will actually publish, not the cheapest setting you can find.

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.
