Kling 4.0 4K output vs Sume: 1080p for Kling 3, 4K on one model
Kling says Kling 4.0 outputs 4K. On Sume, kling-3 stops at 1080p and gemini-omni-flash-1.1 is the model that lists 4K. Rows and the 4K price per 10 s.
Kling's announcement lists 4K output for Kling 4.0, with 10-bit HDR at 1080p and 4K marked coming soon. On Sume, kling-3 outputs 720p or 1080p. The only Sume video model whose resolutions include 4K is gemini-omni-flash-1.1, which lists 360p, 720p, 1080p and 4K, for 3 to 10 seconds with audio always on.
So a 4K clip from Sume today comes from Gemini Omni Flash 1.1, not from a Kling model.
What does 4K cost on Sume?
Sume bills list price times 1.25, rounded up to the cent. gemini-omni-flash-1.1 lists $0.30 per second at 4K, so a 10-second 4K clip is 10 x $0.30 x 1.25 = $3.75. At 1080p the list is $0.15 per second, which gives $1.88 for 10 seconds once rounded up.
| Resolution | List per second | Billed for 10 s (list x 1.25) |
|---|---|---|
| 360p | $0.03 | $0.38 |
| 720p | $0.10 | $1.25 |
| 1080p | $0.15 | $1.88 |
| 4K | $0.30 | $3.75 |
Is 4K worth it for a social ad?
Often not. A 4K master mostly helps when you plan to crop or reframe, and it costs 2x the 1080p rate per second. Generate at 1080p, check the result, and move to 4K only for the winners.
What about the HDR claim?
Kling's page marks 10-bit HDR as coming soon, so treat it as not yet available. Sume's catalog rows do not list HDR for any video model, so do not promise HDR delivery from a Sume job.
