It is a separate 9B model from Black Forest Labs (<a href="https://huggingface.co/black-forest-labs/flux-3-image-klein-pup" rel="nofollow">black-forest-labs/flux-3-image-klein-pup</a>) that expands <code>prompt</code> into such a caption before the text encoder, and a short prompt is all it takes.</p> <p>L’upsampler de prompt transforme une demande brève, accompagnée des images de référence lors d’une édition, en la légende complète de la scène que le modèle reçoit : médium et style, scène, éclairage et caméra, chaque sujet avec ses couleurs, ses matériaux et sa position dans le cadre. Un seul modèle couvre le texte-vers-image, l’édition avec images de référence et la mise en page avec des boîtes. La légende qu’il génère est renvoyée en tant que sortie <code>prompt</code>.
