    }
    
    response = requests.post(API_URL, headers=headers, json=payload)
    
    if response.status_code == 200:
        data = response.json()
        # Process the response to extract image data
        # Implementation depends on response format
        return data
    else:
        print(f"Error: {response.status_code}")
        return None

# Example usage
prompt = "A futuristic cityscape with flying cars and neon signs, cyberpunk style, high detail"
result = generate_image(prompt)

Advanced JavaScript Implementation

const axios = require('axios');
const fs = require('fs');

class GPT4oImageGenerator {
    constructor(apiKey) {
        this.apiKey = apiKey;
        this.baseURL = 'https://api.laozhang.ai/v1/chat/completions';
    }

                }
            ],
            stream: false
        };

        try {
            const response = await axios.post(this.baseURL, payload, {
                headers: {
                    'Content-Type': 'application/json',
                    'Authorization': `Bearer ${this.apiKey}`
                }
            });

            return this.processImageResponse(response.data);
        } catch (error) {
            console.error('Error generating image:', error.message);
            return null;
