Gemini Omni 4K clip cost: a 10-second render is $3.75 on Sume

A 10-second Gemini Omni Flash 1.1 clip at 4K costs $3.00 at the provider list rate of $0.30 per second, and Sume bills $3.75 because it charges list times 1.25. The 360p, 720p and 1080p tiers for the same 10 seconds bill $0.38, $1.25 and $1.88.

The rate card

Sume's Video Router doc lists gemini-omni-flash-1.1 at 360p, 720p, 1080p and 4K, for 3 to 10 seconds, with list prices of $0.03, $0.10, $0.15 and $0.30 per second (fal list, 2026-08-28). Billing uses list times 1.25, rounded up to cents, on each row. The default resolution is 720p and the default duration is 8 seconds.

Sending 4K

The API sends 4K to the provider as its enum value 4k, and for this model only it also accepts a lowercase 4k alias. Duration and resolution go in the normal /v1/videos body. Omni takes 16:9 or 9:16 only, so any other aspect ratio is a 400.

import os, requests

body = {
    "model": "gemini-omni-flash-1.1",
    "prompt": "A glass sphere rolls down a marble staircase. In a single continuous shot.",
    "duration": 10,
    "resolution": "4K",
    "aspect_ratio": "16:9",
}
r = requests.post(
    "https://api.sume.com/v1/videos",
    json=body,
    headers={
        "Authorization": f"Bearer {os.environ['SUME_API_KEY']}",
        "Idempotency-Key": "omni-4k-demo-001",
    },
    timeout=60,
)
print(r.status_code, r.json())

What happens to the money

Sume reserves the estimated cost from the workspace balance when you submit. If the balance cannot cover a $3.75 reserve, the response is 402 insufficient_credits and no job starts. When the job completes, the poll response reports usage.cost as the billable amount. Webhooks and polling are both covered in the Videos guide.

A render ladder

The ladder cost for one keeper is $0.38 + $1.25 + $3.75 = $5.38, against $3.75 if you went straight to 4K, so a ladder only pays when it avoids at least one wasted 4K attempt.

• Draft at 360p for $0.38 per 10 seconds to test the idea.
• Review at 720p for $1.25 to judge motion and audio.
• Approve at 1080p for $1.88 if the platform caps at that size.
• Spend on 4K only for hero assets, at $3.75 per 10 seconds.

A cheaper way to find a good take

Four 4K attempts cost $15.00, while four 720p attempts cost $5.00. Iterate at 720p, fix the prompt, then render the keeper once at 4K. Because the edit path and the generate path share the same catalog row, the rate card above also prices a 10-second 4K edit when the source clip is 10 seconds, though the edit reserve is a hint and not a probe of the output length.
