OpenAI API Integration

Step 1: Get API Access

# Sign up at platform.openai.com
# Generate API key
# Choose appropriate model (GPT-4, GPT-3.5-turbo)

Step 2: Basic Implementation

import OpenAI from 'openai';

const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY
});

async function chatCompletion(userMessage) {
  const completion = await openai.chat.completions.create({
    model: "gpt-4-turbo",
    messages: [
      {
        role: "system",
        content: "You are a helpful business assistant."
      },
      {
        role: "user",
        content: userMessage
      }
    ],
    temperature: 0.7,
    max_tokens: 1000
  });
  
  return completion.choices[0].message.content;
}

Step 3: Advanced Features

// Function calling for structured outputs
const completion = await openai.chat.completions.create({
  model: "gpt-4-turbo",
  messages: messages,
  functions: [
    {
      name: "get_customer_data",
      description: "Retrieve customer information",
      parameters: {
        type: "object",
        properties: {
          customer_id: {
            type: "string",
            description: "The customer ID"
          }
        },
        required: ["customer_id"]
      }
    }
  ],
  function_call: "auto"
});

Cost Optimization Strategies

Understanding OpenAI Pricing (2025)

GPT-4 Turbo:

Input: $0.01 per 1K tokens
Output: $0.03 per 1K tokens

GPT-3.5 Turbo:

Input: $0.0005 per 1K tokens
Output: $0.0015 per 1K tokens

Optimization Techniques

1. Token Management

// Limit response length
max_tokens: 500  // Instead of 2000

// Use shorter prompts
// Good: "Summarize this customer complaint"
// Bad: "Please carefully read and analyze this customer complaint..."

2. Caching Strategy

Cache common responses
Store frequently asked questions
Implement response templates

Savings: 60-80% on repetitive queries

3. Model Selection

Use GPT-3.5-turbo for simple tasks
Reserve GPT-4 for complex reasoning
Implement fallback logic

Cost Reduction: 50-70% with smart routing

4. Batch Processing

Queue non-urgent requests
Process during off-peak hours
Combine related queries

5. Response Streaming

Show partial responses
Reduce perceived latency
Improve UX without extra cost
