<h1 id="flux.2-klein9b-custom-merge">FLUX.2 KLEIN9B — Custom Merge</h1><h2 id="model-overview">Model Overview</h2>A custom merged model based on FLUX.2 [klein] 9B by Black Forest Labs. This model has been tested and optimized for high-quality realistic image generation with exceptional detail in textures, lighting, and atmospheric effects.<h2 id="key-features">Key Features</h2><ul><li>Photorealistic skin rendering with natural subsurface scattering, visible pores, and subtle imperfections</li><li>Exceptional water and wet surface handling — droplets, reflections, refraction, and flow patterns</li><li>Advanced lighting capabilities including volumetric god rays, golden hour, rim lighting, and chiaroscuro</li><li>Superior hair detail with individual strand rendering and natural backlighting effects</li><li>Rich material textures — velvet, linen, silk, leather, wood, metal, and stone</li><li>Strong atmospheric effects — fog, mist, steam, rain, and environmental depth</li><li>Anatomical accuracy for both portrait and full-body generation</li></ul><h2 id="recommended-settings">Recommended Settings</h2>Optimal Configuration (Tested):<ul><li>CFG Scale: 2.0</li><li>Steps: 15</li><li>Scheduler: Euler Ancestral (EulerA)</li></ul>Quick Previews:<ul><li>CFG Scale: 1.5</li><li>Steps: 8-10</li><li>Scheduler: EulerA</li></ul>Complex Scenes (Landscapes, Materials):<ul><li>CFG Scale: 2.0-2.5</li><li>Steps: 15-20</li><li>Scheduler: EulerA</li></ul>Resolution: 1024x1536 (portrait) or 1536x1024 (landscape)<h2 id="best-use-cases">Best Use Cases</h2><ul><li>Photorealistic portraits and character art</li><li>Environmental and landscape photography</li><li>Fashion and material studies</li><li>Cinematic and atmospheric scenes</li><li>Fine art nude photography (artistic interpretation)</li><li>Macro detail shots</li><li>Water and weather effects</li></ul><h2 id="known-limitations">Known Limitations</h2><ul><li>Transparent/translucent fabrics may require LoRA or enhanced prompting for proper rendering</li><li>Text rendering is readable but not perfect — acceptable for most use cases</li><li>Complex multi-element scenes may require 2-3 generations for optimal results</li><li>Official 4-step inference is too low for detailed work — 15 steps recommended</li></ul><h2 id="technical-details">Technical Details</h2><ul><li>Base Model: FLUX.2 [klein] 9B by Black Forest Labs</li><li>Architecture: Rectified Flow Transformer</li><li>Type: Step-distilled model (optimized for speed)</li><li>License: Refer to original FLUX.2 license terms</li></ul><h2 id="performance-notes">Performance Notes</h2>This model excels at organic, natural scenes with complex lighting. The EulerA scheduler at 15 steps provides the best balance between speed and quality. While the official recommendation is 4 steps at CFG 1.0, extensive testing shows 15 steps at CFG 2.0 delivers significantly better results for detailed work without sacrificing the speed advantage of distilled models.<h2 id="credits">Credits</h2>Base model by Black Forest Labs.
