Test one video prompt on ten models for under $7 (Python sweep)

The cheapest way to compare one prompt across Sume's video models is a 5-second sweep at each model's lowest sensible resolution: ten ids cost $5.60 in total, and $3.21 without Kling 3 and Seedance 2.5. Five seconds is inside every model's duration range, so one duration value works for the whole loop.

Cost of the sweep

Kling 3 has no resolution input here and is priced with its default sound on; Omni Flash always includes audio.

The script

Each job gets its own Idempotency-Key, so rerunning the script after a timeout does not double-charge. Aspect ratio is left out so it works for the models that do not take one.

import os, requests
H = {"Authorization": "Bearer " + os.environ["SUME_API_KEY"], "Content-Type": "application/json"}
PROMPT = "A barista pours latte art, slow push-in, warm window light"
RUNS = [("grok-imagine-video-1.5", "480p"), ("gemini-omni-flash-1.1", "360p"),
        ("wan-3.0", "480p"), ("minimax-h3", "480p"), ("minimax-h3-max", "480p"),
        ("seedance-2-mini", "480p"), ("seedance-2-fast", "480p"),
        ("seedance-2", "480p"), ("seedance-2.5", "480p"), ("kling-3", None)]
for model, res in RUNS:
    body = {"model": model, "prompt": PROMPT, "duration": 5}
    if res:
        body["resolution"] = res
    r = requests.post("https://api.sume.com/v1/videos",
                      headers={**H, "Idempotency-Key": "sweep-1-" + model},
                      json=body, timeout=60)
    print(model, r.status_code, r.json().get("polling_url") or r.json())

After the sweep

Drop the two or three models whose clips do not suit the brief, keep the rest, and repeat with a second prompt. A 402 on any row means the balance did not cover that hold; the other rows are unaffected.

Keeping the sweep honest

Keep the prompt, duration and aspect handling fixed, and write down the date. Lowest-resolution clips tell you about motion, framing and prompt adherence; they do not tell you how a model looks at 1080p. Once two or three ids survive, repeat the winners at the resolution you will publish.

Sume reserves the full price at submit, so the number in the table is also the amount that must be free in the balance when you send the request. If it is not, the call fails with 402 insufficient_credits before any provider work starts.
