Seedream 5.0 Lite 9MP (3072x3072) vs Sume's resolution tiers

fal lists Seedream 5.0 Lite at $0.035 per image with output up to 9MP (3072x3072). Sume's API does not take a megapixel number: resolution is a tier (512, 1K, 2K or 4K), and a model accepts only the tiers its catalog descriptor lists. So bytedance-seed/seedream-5-lite may or may not offer a tier that reaches 3072 on a side; read supported_parameters.resolution for it before pinning one.

The model facts are from fal's Seedream 5.0 Lite page, read 2026-10-03. The request rules are from the Image API docs.

What fal's page says

Seedream 5.0 Lite is described for product mockups, marketing assets and creative iteration. It takes detailed natural-language prompts, returns PNG via URL or data URI, and ships with a content filter on by default that the platform lets you switch off in controlled setups.

Pinning a tier on Sume

The docs say Sume normalises resolution to 512, 1K, 2K or 4K, and that a request using a value the model does not list is rejected with 400 unsupported_parameter rather than silently dropped. The script below prints the resolution tiers each catalog row declares.

import os
import requests

key = os.environ["SUME_API_KEY"]
url = "https://api.sume.com/v1/images/models"
resp = requests.get(url, headers={"Authorization": f"Bearer {key}"}, timeout=30)
resp.raise_for_status()
for model in resp.json()["data"]:
    tiers = model["supported_parameters"].get("resolution", {}).get("values", [])
    print(model["id"], tiers)

Limits

Do not assume the fal 9MP ceiling carries over: Sume's own docs say its catalog rows are what governs a request, and fal's content-filter switch is not exposed by Sume's schema. Treat the catalog as the contract.
