10 Creative Projects You Can Build with Picogen

Advanced Picogen Tips for Faster, Higher-Quality Results

1. Choose the right model and settings

• Model: Use a higher-capacity model for quality; switch to smaller models for speed.
• Resolution: Start with the target resolution to avoid upscaling artifacts.
• Sampling steps: Reduce steps for speed but keep enough (e.g., 20–40) to avoid noise; increase only when detail is needed.

2. Optimize prompts and negative prompts

• Concise positives: Put critical descriptors first (style, subject, lighting).
• Negative prompts: Explicitly exclude common artifacts (blurry, low-res, deformed limbs).
• Token economy: Use precise terms instead of long, vague descriptions to guide the model more efficiently.

3. Use progressive refinement

• Draft → refine: Generate lower-resolution drafts to find a composition, then rerender at high resolution.
• Multi-pass editing: Tweak prompts between passes (e.g., tighten lighting or add detail) rather than forcing extremes in one pass.

4. Seed control & batch strategies

• Deterministic seeds: Use fixed seeds for reproducibility and to iterate on parameters without changing composition.
• Batches: Generate batches with varied seeds and slight prompt permutations to find best outputs quickly.

5. Leverage image conditioning and references

• Image prompts: Supply reference images for composition, color palette, or textures.
• Masking & inpainting: Use masks to preserve desired regions while re-rendering parts that need improvement.

6. Post-processing pipeline

• Denoise carefully: Apply controlled denoising or sharpening—overdoing it creates halos and artifacts.
• Upscaling: Use AI upscalers tuned for texture preservation (2× then 2× if needed) rather than one big upscale.
• Color grading: Apply subtle color correction and local contrast to enhance perceived detail.

7. Hardware and runtime tweaks

• Batch size vs VRAM: Lower batch sizes to fit larger resolutions/precision into GPU memory.
• Precision: Use mixed precision (fp16) for faster runs; switch to full precision only if quality issues appear.
• Caching: Cache frequently used models and embeddings to reduce load time.

8. Prompt engineering techniques

• Weighting: Use emphasis (if supported) to prioritize crucial words or phrases.
• Style anchors: Include an artist or style reference only if it consistently produces the desired look.
• Avoid contradictions: Don’t mix mutually exclusive descriptors (e.g., “soft-focus” and “crisply detailed”).

9. Quality-control checklist

• Anatomy/structure: Check for distortions in faces/hands; use targeted inpainting if needed.
• Edges & textures: Inspect for unnatural tiling or repeating patterns.
• Composition: Ensure focal point, lighting, and contrast guide the eye.

10. Iteration workflow (practical example)

1. Generate 4 low-res variations (512px) with varied seeds and concise prompts.
2. Select best composition; rerun at 1024–2048px with increased steps and a refined prompt.
3. Use masked inpainting to fix small issues.
4. Upscale 2× with a texture-preserving model, then apply gentle sharpening and color grade.
