Multi-prompt weighting: cat::2 dog::1 (cat 2x stronger)
Describe: Upload image → get prompt suggestions
Blend: /blend to merge 2-5 images
DALL-E 3
- Natural language only, no parameters
- Be descriptive, not keyword-heavy
- Specify: "HD quality" or "vivid style" in prompt
- Text rendering: Describe font, placement, content explicitly
- Avoid: Lists of keywords, technical jargon
Stable Diffusion / SDXL / Flux
(important term:1.3), normal term, (less important:0.8)
Negative prompt: ugly, blurry, deformed, watermark
| Feature | Syntax |
|---|---|
| Weight up | (word:1.2) to (word:1.5) |
| Weight down | (word:0.5) to (word:0.8) |
| LoRA | <lora:model_name:0.8> |
| Embedding | embedding:name |
| Blend | `[cat |
CFG Scale: 7-12 typical (higher=more prompt adherence) Samplers: DPM++ 2M Karras (quality), Euler a (speed)
Nano Banana (Gemini)
[Narrative description, not keywords]
Captured with 85mm lens, soft bokeh, natural lighting
Key features:
- 32K token context (complex prompts OK)
- Narrative paragraphs > keyword lists
- Hex colors for precision:
#9F2B68 - Text rendering: Describe font, placement explicitly
- Multi-image: Up to 14 reference images
- Search grounding: Real-time data (weather, events)
- Thinking mode: Complex composition reasoning
Aspect ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 Resolution: 1K, 2K, 4K (use uppercase K)
Best practices:
- ALL CAPS for critical requirements
- Markdown lists for multiple rules
- "NEVER include..." for negative constraints
- Photography terms anchor quality
Imagen 4 / Veo 3.1
- Natural language, descriptive
- Aspect ratio in text: "16:9 landscape format"
- Veo: Cinematography keywords most powerful
- Camera movements: pan, tilt, dolly, crane, tracking
- Scene transitions: cut, fade, dissolve

Iterative Workflow
- Start: Subject + style + quality modifier
- Add: Lighting + composition + camera
- Test: Generate 4 variations
- Refine: Adjust weights, add negatives
- Upscale: Select winner, increase resolution
