Wskazówki dotyczące optymalizacji wydajności

1. Tworzenie promptów dla Seedream 4.5

  • Używaj profesjonalnej terminologii: „commercial photography”, „cinematic lighting”, „ultra 4K”
  • Określ kompozycję: „golden ratio”, „rule of thirds”, „diagonal composition”
  • Dodaj wytyczne jakościowe: „professional grade”, „commercial standards”, „print-ready”
  • Korzystaj z zaawansowanych funkcji: „enhanced visual refinement”, „advanced lighting logic”
// Optimized prompt structure
const buildOptimizedPrompt = (subject, style, quality, composition) => {
  return `${subject}, ${style}, ${quality}, ${composition}, ultra 4K resolution, commercial photography standards, enhanced visual refinement`;
};

// Examples
const prompts = [
  buildOptimizedPrompt(
    "luxury watch product photography",
    "professional studio lighting with cinematic color grading",
    "commercial grade quality",
    "golden ratio composition with background blur"
  ),
  buildOptimizedPrompt(
    "modern architecture visualization",
    "dramatic natural lighting with realistic shadows",
    "print-ready 4K quality",
    "diagonal composition with leading lines"
  )
];

2. Wybór proporcji obrazu

Wybierz optymalne proporcje obrazu dla swojego zastosowania:

const aspectRatioGuide = {
  '1:1': 'Social media posts, profile pictures, product shots',
  '4:3': 'Traditional displays, presentations, desktop wallpapers',
  '3:4': 'Mobile screens, portrait photography, book covers',
  '16:9': 'Video thumbnails, wide banners, landscape photography',
  '9:16': 'Mobile stories, vertical videos, smartphone wallpapers',
  '3:2': 'Classic photography, print media, photo frames',
  '2:3': 'Portrait prints, magazine covers, book layouts',
  '21:9': 'Ultra-wide banners, cinema displays, panoramic shots'
};

const selectOptimalRatio = (useCase) => {
  const ratioMap = {
    'social_media': '1:1',
    'youtube_thumbnail': '16:9',
    'instagram_story': '9:16',
    'website_banner': '21:9',
    'product_catalog': '1:1',
    'magazine_cover': '2:3',
    'landscape_photo': '3:2'

}

// Usage example
const client = new Seedream45Client('YOUR_API_KEY', { concurrentRequests: 3 });

const commercialPrompts = [
  'Professional luxury car photography with cinematic lighting',
  'High-end fashion photography with commercial quality',
  'Premium food photography with perfect composition',
  'Corporate headshot with professional studio lighting'
];

const results = await client.generateImageBatch(commercialPrompts, {
  size: '4:3',

});

Wdrożenie produkcyjne: na co zwrócić uwagę

1. Zarządzanie kluczem API

// Environment-based configuration
const config = {
  apiKey: process.env.POYO_API_KEY,
  baseURL: process.env.POYO_API_URL || 'https://api.poyo.ai',
  timeout: parseInt(process.env.API_TIMEOUT) || 30000,
  retries: parseInt(process.env.API_RETRIES) || 3
};

// Validate configuration
if (!config.apiKey) {
  throw new Error('POYO_API_KEY environment variable is required');
}

2. Monitorowanie i logowanie

import logging
from datetime import datetime

# Configure logging
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

class Seedream45Monitor:
    def __init__(self):
        self.generation_stats = {
            'total_requests': 0,
            'successful_generations': 0,
            'failed_generations': 0,
            'total_credits_used': 0
        }

    def log_generation_request(self, prompt, size, task_id):
        logger.info(f"Generation request submitted - Task: {task_id}, Size: {size}, Prompt: {prompt[:50]}...")
        self.generation_stats['total_requests'] += 1

    def log_generation_success(self, task_id, image_url):
        logger.info(f"Generation completed successfully - Task: {task_id}, URL: {image_url}")
        self.generation_stats['successful_generations'] += 1
        self.generation_stats['total_credits_used'] += 5  # Seedream 4.5 costs 5 credits

    def log_generation_failure(self, task_id, error_message):
        logger.error(f"Generation failed - Task: {task_id}, Error: {error_message}")
        self.generation_stats['failed_generations'] += 1

    def get_stats(self):
        success_rate = (self.generation_stats['successful_generations'] /
                       max(self.generation_stats['total_requests'], 1)) * 100

        return {
            **self.generation_stats,
            'success_rate': f"{success_rate:.2f}%",
            'average_cost': self.generation_stats['total_credits_used'] /
                          max(self.generation_stats['successful_generations'], 1)
        }

# Usage
monitor = Seedream45Monitor()

def generate_with_monitoring(prompt, api_key, size='16:9'):
    try:
        # Submit generation
        result = generate_image(prompt, api_key, size)
        if result:
            monitor.log_generation_request(prompt, size, result['task_id'])

            # Wait for completion
            final_result = wait_for_completion(result['task_id'], api_key)

            if final_result and final_result.get('files'):
                monitor.log_generation_success(
                    result['task_id'],
                    final_result['files'][0]['file_url']
                )
                return final_result
            else:
                monitor.log_generation_failure(result['task_id'], "No files in result")
                return None

    except Exception as e:
