Qwen Image Edit Plus: $0.03 a megapixel for text edits

Qwen Image Edit Plus, listed on fal as Qwen-Image-Edit-2509, costs $0.03 per megapixel and is described as having superior text editing and multi-image support. Commercial use is permitted per the page. Sume's docs list its own Qwen row, so check whether it takes references before planning an edit.

Facts are from fal's Qwen Image Edit Plus page, read 2026-10-03.

What the page says

The page does not state a maximum number of input images or a cap on output size, so this post does not either. It shows three example images added in its demo.

Read the Sume row

List the models and look for the Qwen row's reference range.

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"]:
    params = model["supported_parameters"]
    refs = params.get("input_references", {}).get("max", 0)
    n_max = params.get("n", {}).get("max", 1)
    print(model["id"], "refs:", refs, "n:", n_max)

Limits

A per-megapixel fal price is not Sume's price. Sume prices what its row lists in endpoint pricing, and the docs say that is the amount charged. Reference limits for the Sume row are in the catalog, not on fal's page.
