AI digital planner cover art on Seedream 5 Lite: $0.04375 each

For AI digital planner cover art, call bytedance-seed/seedream-5-lite with a 3:4 or 4:5 aspect_ratio: Sume lists it at $0.035 per image and bills list times 1.25, which is $0.04375, so six cover options cost $0.2625. Rerun the same palette phrase on each call so the set looks matched.

Planners are sold as files, and the cover is the product thumbnail. Prices and ratios are from Sume's Image API page and the catalog source, read on 2026-10-05. Seedream's list includes 1:1, 4:5, 5:4, 3:4, 4:3, 3:2, 2:3, 16:9 and 9:16, so one model covers portrait and landscape covers.

What does a cover set cost?

Keep one palette and one motif in every prompt so the set reads as a series.

How do I request a cover?

Name the palette and motif, and leave the title area empty.

import os, requests

body = {
    "model": "bytedance-seed/seedream-5-lite",
    "prompt": "Digital planner cover: soft sage green and cream, a minimal line drawing of a sprig of olive leaves, calm, empty space in the center for a title, no text",
    "aspect_ratio": "3:4"
}
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?

• Put the same palette words in every prompt of the set.
• Add the title and year in your design tool.
• Check the storefront's cover size and crop 3:4 if needed.
• Compare usage.cost with 6 x $0.04375.
