fal lists Seedream 5.0 and Krea 2: find what Sume's image catalog has

fal.ai/models lists Seedream 5.0, GPT Image 2.5, Flux 2, Nano Banana 2, Ideogram 4 and Krea 2 among its image models. Which of those you can call through Sume is answered by GET /v1/images/models, not by this page, and the script below prints the matches for each name.

Sume's docs confirm two of the six by name: GPT Image 2.5 and an Ideogram release, the latter as 4.5.

What each source confirms

Names from the fal listing, and what the Sume Image API page says about them, read 2026-10-03.

Check the live catalog

The script fetches the image catalog and searches model ids and names for each keyword. A keyword with no hit means the catalog does not list it today, not that it never will. Names are matched case-insensitively and loosely because ids use provider slugs.

import os, requests

WANTED = ["seedream", "gpt-image-2.5", "flux", "banana", "ideogram", "krea"]
r = requests.get("https://api.sume.com/v1/images/models",
                 headers={"Authorization": "Bearer " + os.environ["SUME_API_KEY"]},
                 timeout=60)
r.raise_for_status()
models = r.json()["data"]

for word in WANTED:
    hits = [m["id"] for m in models
            if word in m["id"].lower() or word in (m.get("name") or "").lower()]
    print(f"{word:<14}", hits or "no match in catalog")

How to use the result

Treat a model name as a search term until the catalog turns it into an id.

• Once you have an id, read its capabilities from /v1/images/models/{model_id}/endpoints before pinning size, quality or references.
• A parameter the model does not list returns 400 unsupported_parameter instead of being dropped, so a wrong assumption fails fast.
• If a name is missing, use sume/auto to let Image Router choose, or pick the closest listed id.
• Re-run the check when a vendor announces a new version, since catalogs change independently of listings.

A note on version names

Version numbers drift between lists: a listing may say Ideogram 4 while the product page says 4.5, and Sume's page names 4.5. Compare ids, not marketing names, and keep the id in your config rather than a label in your prompt.
