import openai

# Configure laozhang.ai API gateway
openai.api_base = "https://api.laozhang.ai/v1"
openai.api_key = "your-laozhang-api-key"

def generate_image_optimized(prompt, quality="low"):
    response = openai.Image.create(
        model="gpt-image-1",
        prompt=prompt,
        size="1024x1024",
        quality=quality,  # Choose quality level based on needs
        n=1
    )
    
    # Calculate cost
    cost_per_image = {"low": 0.006, "medium": 0.024, "high": 0.102}
    estimated_cost = cost_per_image[quality]
    
    return response.data[0].url, estimated_cost

# Example call
image_url, cost = generate_image_optimized(
    "professional headshot photo", 
    quality="low"
)
print(f"Generated image URL: {image_url}")
print(f"Estimated cost: ${cost}")

This example demonstrates laozhang.ai’s cost advantage over the official API. Through the gateway, low-quality image costs drop from $0.01 to $0.006, saving 40% in fees. For large-scale applications, these savings become even more significant.

Quality Level Selection: Balancing Cost and Effect

GPT-image-1 offers three quality levels, each suitable for different scenarios. Low-quality mode is suitable for rapid prototyping and content preview, medium quality meets most commercial application needs, and high quality is used for printing and professional display occasions.

In practical applications, we recommend adopting a progressive quality strategy. First, use low-quality mode to validate the design direction, then generate high-quality versions once satisfied. This approach maximizes cost efficiency while ensuring final quality.

Quality level selection should also consider the output purpose. Medium quality can be chosen for social media sharing, low quality is sufficient for mobile app embedded images, while marketing materials require high-quality output.

Batch Processing Optimization: Cost Control for Large-Scale Image Generation

For applications requiring large volumes of image generation, batch processing technology can significantly reduce average costs. By combining multiple image generation requests into batch processing, network overhead and system processing costs can be reduced.

Batch Processing vs Single Call Cost Comparison

The core of batch processing optimization lies in request merging and resource reuse. When the system detects similar generation requests, it automatically aggregates them, reducing per-generation costs through shared computing resources. This optimization is particularly effective when processing templated image generation. Understanding GPT-image-1 concurrent limits is crucial for developing batch processing strategies.

laozhang.ai’s batch processing system supports up to 100 requests in batch processing, averaging 20-40% cost savings. Additionally, batch processing mode provides better concurrency control, avoiding rate limiting issues that might result from frequent API calls.
