Recraft V4 Styles: 10 references, and the Sume Recraft id

Recraft V4 Styles, released in August 2026, matches a style from one reference image or as many as 10, in a Precise or a Flexible mode. Sume does not list a V4 Styles id. Its Recraft entry is recraft/recraft-v4, a text-to-image model, so a request with input_references for it is rejected.

Recraft facts are from its V4 Styles page; Sume facts from Image generation and the catalog code, read 2026-10-01.

What does Recraft V4 Styles do?

The page says you attach a reference, generate, and nothing needs training or fine-tuning. Similar references sharpen the match, and a wider mix widens the range. References can come from other generators, brand libraries or old campaign assets. It is available in Recraft Studio and through the Recraft API.

What is the difference between Precise and Flexible?

Precise is for "match this exactly" and follows a reference's texture, palette and rendering. Flexible is the default and the looser read, for the mood of a reference rather than a copy. The page names four models: recraftv4_styles, recraftv4_styles_pro, recraftv4_styles_vector and recraftv4_styles_pro_vector.

Does the Sume Recraft id take references?

No. The catalog row for recraft-v4 is marked text-to-image only, with image_urls not accepted. The Sume input_references field is documented as "Reference images for image-to-image", but the docs say a parameter the selected model does not list is rejected with 400 unsupported_parameter rather than silently dropped. A Precise or Flexible setting has no field to carry it either.

How can I do style-matched work on Sume?

Pick a model that lists reference input in the catalog instead of sending references to Recraft. Reference images in the image API covers which ones do, and which image model compares the catalog. Check the model's listed parameters before you build a flow around it.
