Edit models Morphic names versus what the Sume catalog lists

Morphic says Ideogram 4.5 is coming to its canvas and that, until then, image editing there runs on Seedream 5.0 Pro, Nano Banana 2 and GPT Image 2.5. On Sume, GPT Image 2.5 and Ideogram 4.5 are both listed; Nano Banana 2 is retired and its ids run as Nano Banana 2.1; and the docs and pricing code show no Seedream 5.0 Pro, only Seedream 4.5 in the docs and a Seedream 5 lite in the code. Read the live catalog before you plan around any of them.

The comparison

What the Morphic page does and does not show

The page is a launch explainer for Ideogram 4.5, and it says plainly that its before-and-after examples were not made with Ideogram 4.5. They were made with the models live on Morphic, each source image generated first and then edited with the prompt shown. So the prompts on the page, such as "Change the vase glaze to cobalt blue, keep the light and shadows", are illustrations of the kind of edit, not output from the new model.

That matters for your testing. The claims about untouched pixels, no drift and masks come from Ideogram's description of 4.5. They are not shown on the page. Test them yourself on the model Sume lists, with the script in measuring softening and colour creep.

How to use this list

Be careful with names. Vendors rebrand and version models quickly, and "Pro" or "lite" suffixes mean different capability and price tiers. A model with a similar name in the Sume catalog is not the same model, so match on the id and the description in the list response, not on the marketing name.

If you read a vendor page and want to know what you can call, check three things in order. First, the model id: does GET /v1/images/models list it? Second, its parameters: does it list input_references, and what is the max? Third, price: the pricing array on the endpoint record. The first answer for a retired id is an alias, as with Nano Banana 2, and the job stores the 2.1 id, so your logs show what actually ran.

A Morphic plan is not an API. Morphic lists plans by monthly credits; Sume bills the Image API per image or per token with a documented rate card. Do not compare them without converting to a cost per finished edit.
