Recraft V4 packaging concept art: text-only, WebP on Sume

Is Recraft V4 a good way to explore packaging looks?

It works for concept art, with one limit: on Sume recraft/recraft-v4 is text-to-image only and returns WebP. You describe the pack in words and compare directions; you cannot hand it a dieline or a product photo to edit.

Recraft frames V4 as built for "brand systems and production-ready workflows", with attention to composition, lighting and materials. The vendor page does not mention packaging specifically, so treat packaging as your use of the model, not a claim of it.

What do the vendor pages say?

The fal page prices Recraft V4 at $0.04 per image and lists WebP output. Recraft's own API pricing page lists raster V4 at $0.04 and a separate vector V4 line at $0.08. Neither page documents text rendering, so do not rely on it for legible label copy.

How do I turn concepts into approved art?

Generate a few directions per pack with n up to the catalog range, choose one, and hand the picked WebP to a designer or an edit model. Convert the file first if your pipeline wants PNG or JPEG, as covered in Recraft V4 WebP result: convert before handoff.

If you need a true editable vector, Recraft's separate vector line is the vendor's answer, and the catalog entry here does not include it; see Recraft V4.1 vector SVG API for what is covered.

What does a request look like?

Send the model id, a prompt that names the material and finish, and a ratio. Unsupported parameters such as input_references return a 400, so you find out early.
