It leverages the advanced text encoder capabilities of FLUX to understand semantic context, lighting, and scene composition. The goal is to deliver superior anatomical accuracy - specifically for men.<h2 id="revamped-uncut-and-cut">Revamped Uncut and Cut</h2>We dedicated nearly 1,000 hours across multiple training runs to develop this version of the model. We also developed custom tooling to create a cleaner, higher-quality dataset with more accurate captions.Key Improvements<ul><li>Strong emphasis on removing plastic-like skin textures.</li><li>Unified support for both cut and uncut penises in the same LoRA (uncut is experimental and may need more prompt guidance).</li></ul>Trigger &amp; Prompting Guide<ul><li>Always use clinical, descriptive language for best results. However, tags work okay in this version.</li><li>Do NOT use slang like "cock", "dick", "shaft", etc. Stick to "penis" consistently.</li><li>For uncut: Include "uncut penis" in your prompt.</li><li>For cut: Include "circumcised penis" (or just "penis" if you want the model to decide).</li><li>For flaccid: Try "small flaccid uncut penis" or "small flaccid circumcised penis" to counteract any residual erect bias. This is still a work in progress.</li></ul>Recommended Generation Settings<ul><li>CFG Scale: 3.0 (keeps things natural and avoids overcooking)</li><li>Sampler: res_multistep</li><li>Steps: 25+</li><li>Aspect Ratio: Trained mostly on 9:16 (portrait/vertical) - works best for full-body or focused genital shots, but flexible horizontally too.</li></ul><h3 id="technical-specifications">⚙️ Technical Specifications</h3>Base Model: FLUX.2 Klein 9B-base (Use the fp8 version for best stability)Trigger Phrase: <code>circumcised penis</code> (uncut penis for uncut) (!! READ MORE BELOW !!)Training Res: 1024px (Native), samples generated at 1080p.Use LoRA loader with clip connection for best results.<h2 id="prompting-strategy:-&quot;natural-language&quot;">🎨 Prompting Strategy: "Natural Language"</h2>🛑 STOP TAG SPAM.Do not use comma-separated lists like: <code>1man, solo, realistic, bedroom</code>.✅ USE DESCRIPTIVE SENTENCES.Prompt as if you are describing a photograph to a blind person. Focus on sentence structure, flow, and adjectives.<h3 id="the-semantic-anchor">💡 The Semantic Anchor</h3>While there is no "hard" trigger word, the phrase <code>circumcised penis</code> appears in almost every training caption.How to use it: Integrate this phrase naturally into your sentence (e.g., "...showing detailed anatomy including a circumcised penis..."). This acts as a semantic anchor, signaling the model to prioritize anatomical stability and prevent "morphing."<h3 id="sample-prompt">📝 Sample Prompt</h3>Copy this style for best results:A photo of a 30-year-old man taking a shower behind clear glass. He is muscular with broad shoulders and defined abs, water running down his chest and glistening on his tan skin. He is washing his hair with one hand raised, while his other arm rests against the tiled wall. He is fully naked, and his flaccid circumcised penis hangs naturally. The lighting is bright and overhead, creating high contrast on his wet skin and muscle definition. He looks down with eyes closed, enjoying the warm water.<h3 id="development-status:-alphabeta">🚧 Development Status: Alpha/Beta</h3>This LoRA is a Work In Progress (WIP).<ul><li>Inconsistency: Some seeds are perfect; others may distort.</li><li>Lighting: Complex lighting can sometimes break anatomy. If you get errors, try simplifying to "natural light" or "soft studio lighting."</li><li>Updates: Expect behavior changes between versions as the dataset expands.</li></ul><h3 id="help-improve-the-model">📸 Help Improve the Model</h3>We need more data.
