Using API

const generateImage = async () => {
  const response = await fetch("/api/generator/generate", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      ai_type: "image",
      provider: "openai",
      model: "dall-e-3",
      prompt: "A serene Japanese garden with koi pond",
    }),
  });
  
  const { data } = await response.json();
  
  // Poll for result
  setTimeout(async () => {
    const result = await fetch("/api/generator/query", {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify({ gen_id: data.gen_id }),
    });
    
    const { data: { result_urls } } = await result.json();
    console.log("Image URL:", result_urls[0]);
  }, 15000); // Wait 15 seconds
};

Prompt Engineering

Structure of a Good Prompt

[Subject] + [Action/Pose] + [Environment] + [Style] + [Details]

Example:

Subject: A red sports car
Action: drifting around a corner
Environment: in a neon-lit cyberpunk city
Style: cinematic, dramatic lighting
Details: motion blur, rain reflections, 4K quality

Full Prompt:

A red sports car drifting around a corner in a neon-lit cyberpunk city,
cinematic dramatic lighting, motion blur, rain reflections, 4K quality

Prompt Examples

Portrait:

Professional headshot of a business woman, confident expression,
office background, natural lighting, sharp focus, corporate style

Landscape:

Majestic mountain landscape at sunrise, misty valleys, 
golden hour lighting, wide angle, nature photography

Product:

Modern smartphone on a clean white surface, minimalist composition,
soft shadows, product photography, high-end commercial style

Artistic:

Abstract art, flowing liquid colors, purple and gold gradient,
smooth curves, digital art, 8K resolution

Fantasy:

Dragon flying over ancient castle, magical atmosphere,
fantasy art style, detailed scales, dramatic clouds

Tips for Better Results

1. Be Specific:

   • Instead of "a dog", say "a golden retriever puppy"
   • Instead of "nice lighting", say "soft morning sunlight"

2. Include Style:

   • Photography: "professional photo", "DSLR", "bokeh"
   • Art: "oil painting", "watercolor", "digital art"
   • 3D: "3D render", "octane render", "unreal engine"

3. Mention Quality:

   • "4K", "8K", "high resolution"
   • "professional", "award-winning"
   • "detailed", "intricate"

4. Avoid Negatives:

   • DALL-E doesn't support negative prompts well
   • Focus on what you WANT, not what you don't want

Advanced Usage

Batch Generation

Generate multiple images:

const prompts = [
  "A red apple on white background",
  "A green apple on white background", 
  "A yellow apple on white background",
];

for (const prompt of prompts) {
  await fetch("/api/generator/generate", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      ai_type: "image",
      provider: "replicate", // Cheaper for batch
      model: "black-forest-labs/flux-schnell",
      prompt,
    }),
  });
  
  // Add delay to avoid rate limiting
  await new Promise(r => setTimeout(r, 1000));
}

Style Transfer

Create variations of a concept in different styles:

const basePrompt = "A coffee cup on a wooden table";
const styles = [
  "photorealistic, DSLR, shallow depth of field",
  "oil painting, impressionist style, visible brush strokes",
  "minimalist vector art, flat design, pastel colors",
  "anime style, vibrant colors, cel shading",
];

styles.forEach(style => {
  generateImage(`${basePrompt}, ${style}`);
});

Credit Costs Comparison

Provider	Model	Cost	Speed	Quality
OpenAI	DALL-E 3	5	Medium	Highest
OpenAI	DALL-E 2	5	Fast	Good
Replicate	Flux	3	Fast	Good
Kling	kling-v1	4	Medium	Good

Recommendation:

• Best Quality: OpenAI DALL-E 3
• Best Value: Replicate Flux Schnell
• Balanced: Kling v1

Troubleshooting

Image not generating

Check:

1. Credit balance (need 3-5 credits)
2. API key configured
3. Provider service status
4. Prompt doesn't violate policies

Poor quality results

Try:

1. Switch to DALL-E 3
2. Add quality keywords: "high resolution", "professional"
3. Be more specific in prompt
4. Regenerate with refined prompt

Content policy violation

Error: "Your request was rejected as a result of our safety system"

Solutions:

• Avoid violence, gore, explicit content
• Rephrase prompt to be more general
• Use different provider
• Check provider's content policy

Rate limit exceeded

Error: "Rate limit exceeded"

Solutions:

• Wait a few minutes before retrying
• Use different API key
• Upgrade API quota with provider
• Use alternative provider

Best Practices

1. Test prompts iteratively:

   • Start simple
   • Refine based on results
   • Build a prompt library

2. Choose right provider:

   • Quality needed? → DALL-E 3
   • Cost conscious? → Replicate Flux
   • Specific style? → Try different providers

3. Download immediately:

   • URLs expire
   • Save important results

4. Monitor credits:

   • Check balance regularly
   • Plan generations accordingly
