Veo 3.1 Fast vs Gemini Omni Flash 1.1: 8 s at 720p is about $0.80

On Google's Gemini API an 8-second 720p clip costs $0.80 on Veo 3.1 Fast (8 x $0.10) and $0.8109 on Gemini Omni Flash 1.1 (8 x 5,792 tokens at $17.50 per million). Sume lists Omni but not Veo, and sells Omni at $1.00 for the same 8 seconds (8 x $0.125).

The two Google models are priced almost identically at 720p, so the choice is about what each does, not what it costs. Google lists Veo 3.1 Fast with an audio-inclusive price; Omni is described by Google as a video generation and editing model, and Sume exposes its edit mode through a video_url field in the Video Router.

Three price lists for the same 8 seconds

Runway Dev also resells both families in credits. Its table lists veo3.1_fast with audio at 15 credits per second and gemini_omni_flash_1.1 at 720p at 10 credits per second, at $0.01 per credit.

What Sume covers

Sume's Omni row accepts 3 to 10 seconds in 16:9 or 9:16, with native synced audio always on. It takes image and video inputs but not audio input. Reference to video accepts up to 10 reference images and up to 3 reference videos, each at most 3 seconds, which you cite in the prompt as <IMAGE_REF_0> and <VIDEO_REF_0>.

If you need Veo specifically, Sume is not the place: its video catalog lists Seedance, Wan, MiniMax, Kling 3, Grok Imagine and Omni rows, and no Veo id.

Choosing

For a short vertical ad, Omni on Sume at $1.00 for 8 seconds is the one call that includes audio and edit mode. For pure price on Google, either model costs about the same, so decide on features. Read the live capabilities from GET /v1/video-router/models before you wire either into a product, because each model can have a different envelope.

The following figures use the same list prices as the tables above.

• Sixty 8-second 720p clips: Google Veo 3.1 Fast 60 x $0.80 = $48.00; Google Omni 60 x $0.8109 = $48.65; Sume Omni 60 x $1.00 = $60.00.
• On Runway Dev, the same sixty clips are $72.00 on Veo 3.1 Fast with audio and $48.00 on Omni 1.1.
• The Sume premium over Google's Omni rate is $0.1891 per 8-second clip, which is the 1.25 multiplier on a rounded $0.10.
• Sume's reservation rounds an $1.00 job to exactly 100 cents, so there is no rounding on this one.
