Optimization Strategy Explained

1. Smart Routing

class SmartRouter {
  constructor() {
    this.models = {
      'simple': 'gpt-3.5-turbo',     // Simple tasks
      'complex': 'gpt-4',             // Complex tasks
      'code': 'code-davinci-002',     // Code generation
      'fast': 'claude-instant'        // Fast response
    };
  }
  
  selectModel(task) {
    // Intelligently select model based on task characteristics
    const complexity = this.analyzeComplexity(task);
    const urgency = this.checkUrgency(task);
    
    if (urgency === 'high' && complexity === 'low') {
      return this.models.fast;
    } else if (task.type === 'code') {
      return this.models.code;
    } else if (complexity === 'high') {
      return this.models.complex;
    } else {
      return this.models.simple;
    }
  }
  
  // Cost Optimization: 70% of requests use low-cost models
  // Quality Assurance: Critical tasks use high-performance models
}

2. Concurrency Optimization

// Connection pool management
const connectionPool = {
  maxConnections: 100,
  keepAlive: true,
  timeout: 30000,
  
  // HTTP/2 multiplexing
  http2: true,
  
  // Smart load balancing
  loadBalancer: {
    strategy: 'least_connections',
    healthCheck: true,
    failover: true
  }
};

// Batch request optimization
async function batchProcess(requests) {
  const batches = chunk(requests, 50);
  
  return Promise.all(
    batches.map(batch => 
      Promise.allSettled(
        batch.map(req => processWithRetry(req))
      )
    )
  );
}

3. Caching Strategy

class MultiLevelCache {
  constructor() {
    // L1: In-memory cache (hot data)
    this.memoryCache = new LRUCache({ max: 1000 });
    
    // L2: Redis cache (warm data)
    this.redisCache = new Redis();
    
    // L3: CDN cache (static results)
    this.cdnCache = new CDNClient();
  }
  
  async get(key) {
    // Multi-level cache lookup
    return await this.memoryCache.get(key) ||
           await this.redisCache.get(key) ||
           await this.cdnCache.get(key);
  }
  
  // Smart cache warming
  async warmup(predictions) {
    const hotKeys = await this.predictHotKeys();
    await this.preloadCache(hotKeys);
  }
}

4. Token Optimization

class TokenOptimizer {
  // Prompt compression
  compressPrompt(prompt) {
    return prompt
      .replace(/\s+/g, ' ')           // Compress whitespace
      .replace(/[\n\r]+/g, '\n')     // Compress newlines
      .trim();
  }
  
  // Dynamic truncation
  truncateContext(context, maxTokens) {
    const important = this.extractImportant(context);
    const remaining = maxTokens - this.countTokens(important);
    
    return important + this.summarize(context, remaining);
  }
  
  // Streaming response processing
  async* streamResponse(completion) {
    let buffer = '';
    
    for await (const chunk of completion) {
      buffer += chunk;
      
      // Output when semantic boundary is reached
      if (this.isSemanticBoundary(buffer)) {
        yield buffer;
        buffer = '';
      }
    }
  }
}
