AI gingerbread house design ideas: four Qwen Image takes for $0.10

To get AI gingerbread house design ideas cheaply, call qwen/qwen-image with n: 4 and a short prompt per roof or theme: Sume's catalog lists Qwen Image at $0.02 per image, billed at list times 1.25 as $0.025, so one call of four concept images costs $0.10 and five rounds of ideas cost $0.50.

These are sketches for a baker or a family to choose from, not instructions for building the house; no image model measures candy or icing weight. The prices and limits are from Sume's Image API page and the catalog source, read on 2026-10-05. Gingerbread season starts in the next few weeks, and a concept round that costs ten cents is a fair way to compare roof shapes.

What does a round of concepts cost?

Qwen Image is one of the lowest-priced rows in the Sume catalog. It lists edit support, so after you pick a concept you can send it back as a reference and ask for one change at a time, such as a different door.

How do I ask for four roof styles at once?

Describe one house per call and vary the roof or color in the next call, rather than packing four houses into one prompt; the four takes of a call are variations of the same brief. This request asks for a 4:3 view.

import os, requests

body = {
    "model": "qwen/qwen-image",
    "prompt": "A decorated gingerbread house with a steep white-icing roof, gumdrop buttons and a candy-cane fence, front view, plain light table, no text",
    "aspect_ratio": "4:3",
    "n": 4
}
r = requests.post(
    "https://api.sume.com/v1/images",
    headers={"Authorization": f"Bearer {os.environ['SUME_API_KEY']}"},
    json=body,
    timeout=60,
)
if r.status_code == 200:
    out = r.json()
    for img in out["data"]:
        print(img["url"])
    print("billed USD:", out["usage"]["cost"])
elif r.status_code == 202:
    print("still running, poll:", r.json()["data"]["status_url"])
else:
    print(r.status_code, r.text)

What should I check before building from a concept?

• Look for impossible structure: floating candy, walls with no support. A concept is a style reference.
• Read usage.cost on every response and sum them if you run several rounds.
• Use the same prompt skeleton across rounds so you can compare roofs; the catalog has no seed, so reruns differ.
• A 202 response means the job is still running: poll status_url and read the images from the job result.
