Luma Ray3.2 video-to-video vs Sume Omni edit: cost per clip

To restyle or edit an existing 5-second clip, Luma Ray3.2 video-to-video lists $1.44 at 720p; Sume's Gemini Omni Flash 1.1 edit mode costs $0.625 for the same five seconds at 720p. At 10 seconds it is $2.16 on Luma and $1.25 on Sume. The Luma prices are from the Luma API pricing page (read 2026-10-04).

These are two different models doing the same kind of job, so the price gap says nothing about which edit looks better.

Luma's full ladder

Luma lists Ray3.2 video-to-video at $0.72, $1.44 and $2.16 for a 5-second clip at 540p, 720p and 1080p, and $1.08, $2.16 and $4.32 for 10 seconds. The 10-second price is 1.5x the 5-second price at 540p ($1.08 / $0.72) and 2.0x at 1080p ($4.32 / $2.16), so a longer clip is not a linear step.

How Sume prices an edit

Omni edit mode takes a video_url and a prompt that describes the change; resolution is optional and defaults to 720p. Sume bills the provider list x 1.25 per output second as a function of resolution, per the Video Router docs. The list is $0.10 per second at 720p and $0.15 at 1080p, so Sume is $0.125 and $0.1875 per second.

At 1080p a 5-second edit is 5 x $0.1875 = $0.9375, against $2.16 on Luma; 10 seconds is $1.875 against $4.32.

• Native audio is always on for Omni, so the result carries a soundtrack.
• The edit request carries no duration field; the output follows the source clip, so a 10-second source bills 10 seconds.

Steps to compare on your own clip

• Cut the source to the length you actually need; every second is billed.
• Run the same instruction on both services at 720p.
• Judge the result against your brief, then multiply by the retries you needed.
• Only then compare per-clip cost: price x attempts.

A batch of 50 edits

Fifty 5-second edits at 720p cost 50 x $1.44 = $72.00 on Luma and 50 x $0.625 = $31.25 on Sume, a $40.75 difference. At 1080p they cost 50 x $2.16 = $108.00 on Luma and 50 x $0.9375 = $46.88 on Sume. If the edit lands on the first try, the cheaper model wins on price; if it takes three tries, multiply each by three before comparing.

Caveats

Luma's tiers differ by resolution and HDR options, which multiply the price (HDR is 2x). Omni's edit window is 3 to 10 seconds, so longer clips need splitting. Prices were read on 2026-10-04 and promotions change.
