Omni 1.1 Flash 1080p vs Wan 3.0 1080p: price for 30 seconds

Thirty seconds of 1080p video costs $7.50 on Sume's wan-3.0 in one request, and $5.625 on gemini-omni-flash-1.1 as three 10 second clips. Omni is cheaper per second at 1080p ($0.1875 against $0.25), but it stops at 10 seconds per clip, so you pay for the joins in editor time.

The rates

Sume bills provider list times 1.25 for each output second. Omni's catalog list is $0.03, $0.10, $0.15 and $0.30 at 360p, 720p, 1080p and 4K (fal, 2026-08-28). Wan's is $0.05, $0.10 and $0.20 at 480p, 720p and 1080p (fal, 2026-08-24).

A note on rounding

The totals are exact products; a billed amount can differ by a fraction of a cent from the rounding of the billing path, so treat $5.625 as about $5.63.

The limit that matters

Omni 1.1 Flash on Sume takes 3 to 10 seconds per request. Google's own post describes scene extension that analyzes up to 10 seconds of prior context and reaches up to 40 seconds total in 10 second steps (read 2026-10-05), but the Sume docs say the API does not expose extend, so on Sume a 30 second Omni film is three separate jobs.

What the savings cost

Three clips mean three prompts, three jobs and two cuts. Continuity depends on you: reuse the style sentence, carry a character description in every prompt, and use the last frame of one clip as the first frame of the next via image_url. Omni's edit mode and its 4K tier are things Wan 3.0 does not offer on Sume.

Where Wan still wins

Wan 3.0's advantage is a single 30 second take in one job, with audio and audio references (up to 5 audio files, alongside an image or video). Omni has native audio always on, no audio references, and 16:9 or 9:16 only. If your ad is vertical or widescreen and you can live with cuts, the $1.875 saving at 1080p is real; at 720p there is no saving at all.

At campaign scale

Budget per campaign: twenty 30 second 1080p films are 20 x $7.50 = $150.00 on Wan 3.0 and 20 x $5.625 = $112.50 on Omni. The $37.50 gap pays for editing time only if your joins are quick.

A worked comparison

Take a 30 second 1080p ad for a product page. On Wan 3.0 it is one job at $7.50. On Omni it is three jobs at 10 seconds each: 3 x 10 x $0.1875 = $5.625. If you need two takes of each, double both: $15.00 against $11.25. The gap grows with the number of takes, but so does the number of joins you must check.

If the plan is a 15 second spot, Omni's price advantage is the same per second but the join count drops to one, and the comparison tilts toward Omni. For 30 seconds in a single take, only Wan 3.0 offers it in this pair.

Drafting cheaply on either

Both rows have a cheap tier for first drafts: Wan at 480p ($0.0625 per second) and Omni at 360p ($0.0375 per second). A 30 second draft is $1.875 on Wan and $1.125 on Omni. Draft first, approve the prompt, and pay for the final tier once.

Planning the spend

Decide the number of finished films per month first, then multiply. Ten 30 second 1080p films a month are $75.00 on Wan 3.0 and $56.25 on Omni in three-clip form. Add a draft pass at the cheap tier for each: ten Wan drafts at 480p are $18.75 and ten Omni drafts at 360p are $11.25.

Sume reserves the estimated cost when a job is submitted and shows the final amount in usage.cost, so check the reserve against your balance before a batch of ten jobs, not after.

Which one for which brief

Pick Wan 3.0 when the film must be one continuous take, when you want the 480p draft tier, or when you want to avoid editing joins. Pick Omni when you need 4K, when clips are short, or when the saving at 1080p matters more than continuity. Neither choice is permanent, since both ids are in the same router and you can switch by changing the model field.
