AI Component Specification

Overview

The AI component is a core differentiator for MemeMint, enabling users to generate memecoin images through natural language prompts. For the PoC, we'll implement a simplified but functional version that demonstrates the concept while controlling costs and complexity.

Functional Requirements

1. Image Generation

Capabilities:

• Generate meme-styled images from user text prompts
• Support basic style variations
• Maintain consistent quality and aspect ratio
• Generate images in under 10 seconds
• Support fixed resolution output (512x512px)

Limitations for PoC:

• Limited to 3 free generations per user
• No animations or video
• Simplified "Legendary" traits system
• Limited customization options

2. Prompt Engineering

Requirements:

• Implement prompt enhancement to improve generation quality
• Create template system for consistent results
• Handle inappropriate content filtering
• Support basic style guidance terminology

Example Implementation:

function enhancePrompt(userPrompt, style = 'default') {
  const styleModifiers = {
    default: 'high quality, detailed, memetic, vibrant',
    legendary: 'high quality, detailed, memetic, vibrant, golden glow, rare, special effect',
    pixel: 'pixel art style, 16-bit, game art, retro gaming',
    // Add more styles as needed
  };
  
  const basePrompt = `A memecoin logo featuring ${userPrompt}, ${styleModifiers[style]}`;
  return basePrompt;
}

3. Trend Template System

Requirements:

• Create daily trending topic templates
• Support theme-based generation
• Enable community voting on trends
• Pre-generate example images for each trend

Implementation Pattern:

• Daily trend selection via community poll
• Template storage in database
• Parameterized prompt generation

4. Content Moderation

Requirements:

• Implement pre-generation prompt filtering
• Post-generation image safety checking
• User reporting system
• Rejection handling with clear messaging

Technical Approach

AI Service Integration

Recommended Provider Options:

1. Stable Diffusion API

   • Cost-effective for high volume
   • Self-hosting option for later scaling
   • Great customization capabilities

2. OpenAI DALL-E

   • Faster implementation
   • More consistent results
   • Higher cost per generation

3. Midjourney API (when available)

   • Best quality for meme-style images
   • Requires more prompt engineering

For PoC Implementation:

• Use Stable Diffusion via Replicate.com API
• Implement caching to reduce duplicate generations
• Set strict timeout handling (max 15sec)

Response Handling

Success Flow:

1. Receive image binary data
2. Process/optimize for display
3. Store in temporary cache
4. Present to user for confirmation
5. If approved, upload to permanent storage (IPFS)
6. Store metadata with coin record

Error Handling:

1. API timeout → Friendly retry message
2. Content policy violation → Specific guidance message
3. Service unavailable → Fallback to upload option

Optimization Strategies

Cost Management

• Implement result caching for similar prompts
• Batch processing when possible
• Compression of final images
• Tiered access (3 free, then paid)

Performance Optimization

• Client-side loading indicators
• Progressive image loading
• Parallel processing when possible
• Predictive pre-generation for trends

Storage Strategy

• Temporary storage for generation review
• Permanent decentralized storage (IPFS) after minting
• Metadata storage in database with image references

API Interface
