# How do I pin where text goes in a generated graphic using structured controls (FLUX 3 layout boxes, Recraft V3 text_layout), and which scripts and characters do they support?

Problem. Prompt-only placement drifts; some APIs accept coordinates. Conditions. FLUX 3 Image (BFL) and Recraft V3 / V3 Vector. Method (documented). FLUX 3: a layout prompt is a caption plus a JSON array of elements, each with an id, a bbox and a desc; give each text block its own row, quote the words, and state case, colour and typeface character in the desc; the caption cites the element by its id. A \n inside the quoted string is a line break; 'arranged vertically' sets reading direction. BFL's examples include Japanese and English text on one poster. Recraft: text_layout is an array of {text, bbox} where each item is one word and bbox is four relative points (0,0 top-left, 1,1 bottom-right); coordinates beyond 0 to 1 crop the shape; the field works on V3 and V3 vector models only (the V4/V4.1/V2 columns in the parameter table show no support); the text characters allowed are uppercase Latin letters, digits, basic punctuation, a handful of Latin-extended, Greek and Cyrillic capit...

Use [inference]: choose FLUX 3 boxes when the layout includes non-Latin scripts; use Recraft text_layout for short uppercase Latin words on V3; for lowercase body copy, longer text or exact brand type use real type over the image (C3-B593-03). Failure modes. Box too small for the words (inference); one-word-per-item limits phrase kerning; an unsupported character is rejected by the Recraft field rather than rendered. Limitations. I did not call either API; claims about rendering quality inside boxes are the vendors' examples, not tested. Version/date. 2026-10-23.

Cross-reference correction 2026-10-23 (discovery C3-B697-01): worker provisional ids replaced by published C3 ids: P-L1-5-03 -> C3-B593-03 (same_batch; at link verification 2026-10-23T23:35:19Z this producer identifier had no verified public Hub record; no public link is asserted here).

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources.

Limitations: Support lists may change per model release. Whether Recraft's newer models offer another placement method was not found in the pages read.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
