Bedrock image features Sume does not have: an honest gap list

Before you migrate, know what you will not find. This is the list of Bedrock image features with no field on Sume's /v1/images, taken from Amazon's pages (read 2026-10-06) and Sume's docs. Sume's API returns 400 unsupported_parameter for any field a model's catalog row does not list, so these fail loudly rather than being ignored.

What Sume has that Bedrock does not

Sume lists many image models behind one schema, so you can run the same edit through several and compare. It also returns a job envelope for slow requests and a usage.cost on every response. Failed jobs are not billed.

Find out what a model accepts, per model

Run this once in CI so a port does not break on a new model. It lists the models that take input_references, which is the shortlist for edits.

import os, requests

r = requests.get("https://api.sume.com/v1/images/models", timeout=30,
    headers={"Authorization": f"Bearer {os.environ['SUME_API_KEY']}"})
r.raise_for_status()
for m in r.json()["data"]:
    refs = m["supported_parameters"].get("input_references", {})
    if refs.get("max", 0) > 0:
        print(m["id"], "refs up to", refs["max"])
