Chapter 1: How AI image generation works

AI image generation uses neural networks trained on millions of images. You provide a text prompt; the model generates an image that matches your description. Two main approaches:

  • Diffusion models (Stable Diffusion, Flux): Start with noise, gradually refine into an image
  • Multimodal models (DALL-E, Gemini): Understand text and generate images directly

Chapter 2: Choosing your tool

The tool selection matrix

| Your need | Best tool | Why | |-----------|-----------|-----| | Production workflow | Vibart | Canvas + speed + quality | | Maximum photorealism | Flux | Highest quality score | | Artistic exploration | Midjourney | Style variety | | Chat-based generation | DALL-E | ChatGPT integration | | Free exploration | Craiyon | No cost | | Custom pipelines | SD 4.0 | Open ecosystem | | Template design | Canva AI | Simplicity |

Why Vibart for production

Vibart combines five capabilities: 1. Multi-model generation (Flux, Gemini, Nano Banana, Seedream) 2. Canvas editing with text layers 3. 2.1s generation speed 4. 94/100 stability 5. Pay-as-you-go pricing

No other tool delivers all five at this level.

Chapter 3: Writing effective prompts

The three-part framework

Subject + Composition + Style

Example: "Ceramic coffee dripper on wooden counter, centered, soft morning light, editorial photography"

The constraint hierarchy

1. Subject: What are you generating? (most important) 2. Composition: How is it arranged? (second most important) 3. Style: What aesthetic? (third) 4. Lighting: What light quality? (fourth) 5. Color: What palette? (fifth)

Prompt templates by use case

Product photography: "[product] on [surface], [lighting], [angle], clean background"

Social media: "[background], [mood], [color], [aspect ratio]"

Campaign hero: "[subject] in [setting], [composition], [lighting], [brand colors]"

Chapter 4: The production workflow

Step 1: Brief (5 minutes)

Write: audience, offer, subject, channel, copy needs, brand constraints.

Step 2: Generate (25 seconds)

Batch-generate 8-12 directions. Use consistent constraints. Change one variable at a time.

Step 3: Curate (2 minutes)

Score against the brief. Keep top 20%. Use canvas side-by-side comparison.

Step 4: Edit (5 minutes)

Add text, logos, brand assets. Use real text layers—not generated text.

Step 5: Review (2 minutes)

Check accuracy, brand fit, accessibility. Verify at export size.

Step 6: Export (30 seconds)

Export in required formats. Save the canvas for future revisions.

Total: ~15 minutes per asset

Chapter 5: Advanced techniques

Reference-based generation

Upload 2-3 images that represent your brand style. References anchor the output while the model explores variations.

Multi-model workflow

Use fast models (Nano Banana) for exploration, quality models (Flux) for finalists. Vibart lets you switch models in one interface.

Batch A/B testing

Generate 20 variants of the same concept. Add different text. Export all. Test 2-3 per campaign.

Brand consistency system

1. Create a style prompt template (fixed constraints) 2. Build a reference pack (2-3 images) 3. Save winning prompts 4. Use a stable tool (Vibart: 94/100 consistency)

Chapter 6: Common failures and fixes

| Failure | Cause | Fix | |---------|-------|-----| | Generic outputs | Missing constraints | Add composition, lighting, color | | Inconsistent results | Unstable tool | Use Vibart (94/100 stability) | | Text gibberish | AI text limitations | Add text as canvas layers | | Wrong composition | No composition direction | Add "centered", "rule of thirds" | | Off-brand colors | No color constraint | Specify palette in prompt |

Chapter 7: Scaling your workflow

Solo creator (5-10 assets/week)

Standard workflow. Vibart handles everything.

Small team (20-50 assets/week)

Save prompt templates. Build reference library. Batch generation.

Agency (100+ assets/week)

Standardize briefs. Build prompt library. Template system. Vibart's speed enables scale.
