# FLUX.2 Canonical page: https://fuser.studio/models/flux-2 FLUX.2 in Fuser generates and edits images from text and up to ten references, with Turbo, Dev, Pro, Max and Flex versions to trade speed for quality. ## Specs | Spec | Value | | --- | --- | | Versions | Turbo, Dev, Pro, Max, Flex, Klein 4B, Klein 9B | | Inputs | Prompt (text), Images (up to 10 images) | | Output | image | | Cost | 14–1,320 credits per run | Merge up to ten references into clean, photographic images, then climb from fast drafts to polished finals without changing workflow Creator: Black Forest Labs [Composite a scene](https://app.fuser.studio) ## How FLUX.2 works Write the scene, attach references by position, then choose how much quality to spend. One interface covers both text-to-image and reference edits, so you never switch tools between draft and final. ### Structure the scene Write subject first, then action, style and context, or switch to a JSON prompt with hex colors placed beside the objects they colour. ### Attach your references Add up to 10 images and name each by position, such as the jacket from image 2 on the person from image 1. ### Pick a tier and render Draft on Turbo or Klein at the default 8 steps, then move to Pro, Max or Flex for finals and raise steps up to 50 when detail matters. ## What FLUX.2 is good at Reference-driven editing, palette control through hex codes and JSON, and a tier ladder from cheap drafts to production finals, all in sharp photographic rendering with readable type. ### HEX palettes and JSON prompts Write scene, subjects, lighting, camera and color_palette as structured JSON, and set hex codes beside the object they colour. Subjects stay distinct instead of bleeding together. Check the output, since hex colors can drift. ### Ten-image multi-reference blending Merge subjects, garments and products from up to 10 references in one pass, with identity and product form carried through. About 3-6 clean, varied-angle references is the community sweet spot; name each one in the prompt. ### Flex typography control On the Flex tier, raise steps up to 50 and tune guidance to keep headlines legible and layouts crisp. The Flex edit variant refines type in an existing design from references. Costlier, so save it for finals. ### Cheap drafts, then finals Explore on Klein 4B, Klein 9B or Turbo, then rerun the same prompt on Pro or Max for production polish. Distilled tiers render a little flatter, which suits layout and mood checks before you commit. ## Made with FLUX.2 A gallery of architecture, cinema, still life, documentary and product frames, showing clean photographic detail, controlled palettes and materials that hold up across subjects. ### Architectural study in limestone and pickled oak ### Cinematic frame with complementary flare illumination ### Still life with ceramic and scorched basalt ### Documentary portrait of workshop craftsmanship ### E-commerce footwear hero shot ## What people build with FLUX.2 Product teams, art directors, poster designers, lookbook stylists and concept artists reach for it when references need to merge into one scene and a brand palette has to hold. ### E-commerce product compositing Merge several product shots into one clean scene, with product form and identity preserved from your references. Draft on Klein or Turbo, then finish on Pro or Max. ### Brand-color campaign visuals Art directors set a palette with hex codes and structure multi-subject scenes in JSON. Check the render against the brand swatch, since colors can drift darker. ### Poster and sleeve typography Designers refine headlines in existing layouts using references, and Flex gives the steps and guidance to keep type sharp. Longer copy needs more steps. ### Fashion lookbook outfit swaps Lookbook teams place a garment from one reference onto the subject of another. Identity carries through, and a handful of well-chosen references keeps it stable. ### Film and character frames Concept artists keep a character consistent across references, then restage them in new lighting and lenses. Use JSON prompts to keep details from bleeding between subjects. ## FLUX.2 questions ### Which FLUX.2 tier should I use for drafts and which for final renders? Use Klein 4B, Klein 9B or Turbo for drafts, and Pro, Max or Flex for finals. Klein and Turbo are the cheapest tiers and suit fast exploration, though they look slightly flatter. **Pro** gives dependable finals with minimal tuning, **Max** targets the highest fidelity, and **Flex** suits typography and fine detail. Dev is a balanced middle tier with tunable steps and guidance. ### What's the difference between FLUX.2 Flex and Pro? Flex exposes steps and guidance, while Pro uses fixed settings. Flex suits typography-heavy or detail-critical work, with steps up to 50, but it is among the most expensive tiers and slower at high steps. Pro is the better choice for reliable, production-grade finals with minimal tuning, at the cost of fine control. ### What's the difference between Klein 4B and Klein 9B? Klein 9B gives better quality than 4B at a still-low cost. Klein 4B is the cheapest option for drafting and concept exploration, with less fine detail and weaker text. Klein 9B aims at quality close to Dev, but it is still below Pro and Max on detail, and its open 9B weights are non-commercially licensed. Both have edit versions, with fidelity better on 9B. ### How many reference images can FLUX.2 take? Up to 10 images, though the community sweet spot is about 3-6 well-chosen references. Use clean, well-lit images from varied angles, and say what to take from each, for example 'the jacket from image 2 on the person from image 1'. Too many conflicting or near-duplicate references can cause identity drift. Edit costs also rise with the number of images. ### Does FLUX.2 support negative prompts? No, there is no negative prompt. State what you want positively instead, since 'don't include X' lists tend to backfire. Lead with the subject, then action, style and context. ### Will hex color codes match my brand colors exactly? Not guaranteed. Hex codes steer the palette well when placed beside the object they colour, such as 'mug in deep cobalt #1E3A8A', but colors can drift darker or off-hue. Run a check pass against your swatch before shipping brand-critical work. ## Try FLUX.2 on Fuser Merge up to ten references into clean, photographic images, then climb from fast drafts to polished finals without changing workflow [Composite a scene](https://app.fuser.studio) ## Recipes using FLUX.2 - [AI Artifact Remover](https://fuser.studio/recipes/ai-artifact-remover.md): Upload a source image to remove AI-generated artifacts, distortions, and unnatural details while preserving its composition, style, and visual elements. ## Used for - [Creative agencies](https://fuser.studio/solutions/industries/creative-agencies.md): Develop pitches, campaign assets and interactive client work in Fuser.
