Omni Flash 1.1 vs Wan 3.0: a 10-second clip at 1080p, $1.875 vs $2.50

A 10-second 720p clip costs $1.25 on both gemini-omni-flash-1.1 and wan-3.0 on Sume, since both are $0.125 a second. At 1080p, Omni is cheaper: $1.875 against $2.50. Ten seconds is exactly Omni's maximum, so this is the longest clip you can make on that row, while Wan 3.0 runs to 30 seconds.

The grid

Omni lists 360p, 720p, 1080p and 4K, while Wan 3.0 lists 480p, 720p and 1080p. The rows below pair the tiers that exist on both and then show the extras.

What differs besides price

Per Sume's docs, Omni is 16:9 or 9:16 only, accepts up to 10 reference images and up to 3 reference videos of at most 3 seconds each, can edit a source video, and always generates native audio (generate_audio false is rejected). Wan 3.0 accepts 2 to 30 seconds and takes audio and video references.

• If you need a clip longer than 10 seconds, Omni is out.
• If you need silent output, Omni is out. Native audio cannot be turned off.
• If you need 4K, Wan 3.0 is out; Omni's 4K is $0.375 a second.

Budget view

A hundred 10-second 1080p clips are $187.50 on Omni and $250.00 on Wan 3.0, so Omni saves $62.50 per hundred at 1080p. At 720p the two tie at $125.00. The savings case for Omni therefore rests on the 1080p tier, and the case for Wan 3.0 rests on length, silence or audio control.

The 360p draft trick

Omni's lowest tier is 360p at $0.0375 a second, so a 10-second draft is $0.375, which is 40 percent cheaper than Wan 3.0 at 480p ($0.625). If you want to test a prompt before paying for 1080p, 10 drafts on Omni 360p cost $3.75, and 10 finals at 1080p cost $18.75. The whole loop is $22.50, against $25.00 for 10 Wan 3.0 clips at 1080p with no cheaper draft tier than 480p.

This is a price comparison only. Whether a 360p Omni draft predicts the 1080p result is something to test on your own prompts.
