Draft on the fast tier, then scale up. ### Describe the frame plainly Write full scene sentences covering subject, setting, lens and light, and put any words you want rendered in quotation marks. ### Pick shape and add references Set the aspect ratio for your delivery format, or attach up to 10 images and give each a role by order, like image 1 and image 2. ### Draft small, finish large Explore on Klein at 512px to 1K, lock the seed, then rerun on the full model at 2K or 4K in PNG for the final. ## What FLUX.3 Image is good at Readable words, edits that respect what you didn't ask to change, and a fast Klein tier alongside the full-size one for finals up to 4K. ### Typography that belongs in the scene Headlines, signage and date lines render as printed or painted parts of the picture. Quote the exact words and say where they land and what they are printed on. Long paragraphs can still drift, so keep copy short. ### Multi-reference compositing On the edit-image variant, place a product, a surface and a backdrop from up to 10 references into one frame. Give every image a role by order, such as the bottle from image 2 into the counter scene of image 1. ### Surgical edits, fast Klein rounds Swap a garment, recolor a sofa or shift the lighting while the rest of the frame holds. Run quick iterations on the Klein edit tier, then repeat the winning edit on the full model for better identity and small-text fidelity. ### Large-format 2K and 4K finals The full-size tier on text-to-image is built for hero frames where faces, material grain and small type must hold up when cropped. Save 4K for finals, since it takes minutes and costs the most. ## Made with FLUX.3 Image A spread of poster, campaign, film, architecture and product frames, each built around one subject, a tight palette and quoted text where the scene calls for it. ### Architectural visualization with a single yellow door ### Film still with arrested motion ### Campaign frame with integrated headline ### Vertical short-form moment ### Product still life on a surreal set ## What people build with FLUX.3 Image Designers, brand teams and stylists reach for it when a frame has to carry real lettering, survive a crop, or change one element without a reshoot. ### Poster and album art designers Build gig posters, record sleeves and typographic covers where the headline has to read cleanly and the layout is composed for 2:3, 1:2 or square from the first draft. ### Packaging and signage mockups Test label wording, shop signs and shelf-ready packaging, with quoted text rendering as part of the scene instead of an overlay. Use 2K or 4K when the small type matters. ### E-commerce teams swapping products Combine a product, a plinth and a backdrop from separate references, restyle one object and keep the rest of the frame identical across a whole catalog run. ### Fashion and lookbook stylists Swap a single garment on a base photo while pose, background and lighting stay put, then run the same base through other pieces. Check face and color grade closely on every pass. ### Brand campaign art directors Explore routes cheaply on Klein, then deliver wide banners, tall stories and print-ready hero images on the full model in the exact ratio you need. ## FLUX.3 Image questions ### What's the difference between FLUX.3 and FLUX.3 Klein? FLUX.3 is the full-size flagship for final-quality frames, while Klein is a much smaller, faster and far cheaper tier for exploration. Klein is less dependable on dense text and fine texture, and its prompt expansion is on by default because short prompts look generic. Use Klein for concept rounds and layout thumbnails, then rerun the winners on FLUX.3. ### What's the difference between the text-to-image and edit-image variants? Text-to-image generates from a prompt alone, while edit-image works from attached reference images. **Text-to-image** suits posters with exact lettering, hero shots and large-format stills. **Edit-image** restyles backgrounds, swaps garments, rewrites sign text and places a product from one image into another, but identity and color grade can shift, so check results closely. ### Which variant should I use to swap a jacket on an existing photo? Use edit-image. Put the base photo first, name the garment image by order ("replace the jacket with the one from image 2"), and state what must stay unchanged, such as the face and hair. Try it on Klein first for speed, then rerun on FLUX.3 for the final. ### Can it render readable text in posters and signs? Yes, short headlines and signage render well when you put the exact words in quotes and say where they sit and what they are printed on. Long passages of small text can still misspell or drift, and Klein is less reliable on dense text than the full model. ### When should I not use FLUX.3 Image? Skip it for painterly or anime-style illustration, vector logos and icon sets, and exact face-swaps where the color grade must not shift. It is also a poor fit for fast iteration at 4K, which can take minutes and costs the most. Draft on Klein or at lower resolution instead. ### Who makes FLUX.3 Image, and is there an open-weights version? It is made by Black Forest Labs. The full FLUX.3 tier is hosted only, while Klein is also released as open weights under Black Forest Labs' community license, which limits free commercial self-hosting to smaller businesses. ## Try FLUX.3 Image on Fuser Posters, packaging and campaign frames with lettering that reads like real print, plus edits that change one thing and leave the rest alone [Set the type](https://app.fuser.studio) ## Related models - [FLUX.2](https://fuser.studio/models/flux-2.md) - [FLUX.1 Kontext](https://fuser.studio/models/flux-1-kontext.md) - [FLUX.1 [Dev]](https://fuser.studio/models/flux-1-dev.md) - [FLUX1.1 [Pro] Ultra](https://fuser.studio/models/flux1-1-pro-ultra.md) - [Gemini Image](https://fuser.studio/models/gemini-image.md) - [GPT Image](https://fuser.studio/models/gpt-image.md) Node reference: [FLUX.3 Image docs](https://docs.fuser.studio/docs/nodes/image/flux-3-image.md) ## More articles - [Image to STL: Turn a Photo Into a 3D-Printable Model With AI](https://fuser.studio/articles/image-to-stl.md) - [Krea 3 vs FLUX.3 Image: Same-Prompt Test](https://fuser.studio/articles/krea-3-vs-flux-3-image.md) - [FLUX.3 Klein vs FLUX.3 Image: Same-Prompt Test of Quality, Speed, Cost and Editing](https://fuser.studio/articles/flux-3-klein-vs-flux-3-image.md)
