GPT Image 1 API: Pricing, Features & Integration Guide

This guide covers what GPT Image 1 can do, how much it costs, how it compares to GPT Image 1.5, and how to integrate it into your application.

GPT Image 1 Pricing

Pricing is per successfully generated image. Failed generations are not billed. No subscription or monthly minimum required on EvoLink.

GPT Image 1 vs GPT Image 1.5: Which Should You Use?

What Can You Build with GPT Image 1?

Text-to-Image Generation

Generate images from text descriptions. GPT Image 1 handles complex multi-element scenes, specific art styles, and photorealistic rendering.

• Marketing banner generation from campaign briefs
• Product mockup creation for e-commerce listings
• Social media content automation
• Game concept art and character design

Image Editing with Masks

Edit specific regions of existing images using mask-based inpainting. Keep the parts you like, regenerate the rest.

• Remove unwanted objects from product photos
• Change backgrounds while preserving subjects
• Add elements to existing scenes
• Fix imperfections in generated images

Image-to-Image Transformation

Use a reference image as a starting point and transform it based on text instructions.

• Style transfer (photo to illustration, sketch to render)
• Product color variations from a single reference
• Season or lighting changes on architectural photos

How to Integrate GPT Image 1 API

Step 1: Get your API key

Step 2: Send a generation request

GPT Image 1 uses the OpenAI-compatible images endpoint:

import openai

client = openai.OpenAI(
    api_key="your-evolink-api-key",
    base_url="https://api.evolink.ai/v1"
)

response = client.images.generate(
    model="gpt-image-1",
    prompt="A professional product photo of a ceramic coffee mug on a marble countertop, soft natural lighting, 4K quality",
    n=1,
    size="1024x1024"
)

image_url = response.data[0].url

Step 3: Image editing with masks

response = client.images.edit(
    model="gpt-image-1",
    image=open("original.png", "rb"),
    mask=open("mask.png", "rb"),
    prompt="Replace the background with a tropical beach at sunset",
    n=1,
    size="1024x1024"
)

Step 4: Deploy and monitor

Track usage and costs in the EvoLink dashboard. Set up billing alerts to control spend.

FAQ

How much does GPT Image 1 API cost?

GPT Image 1 costs $0.042 per image on OpenAI direct and $0.034 per image on EvoLink. Pricing is per successful generation with no monthly minimum.

What is the difference between GPT Image 1 and gpt-image-1?

They are the same model. "GPT Image 1" is the display name and "gpt-image-1" is the API model ID you use in your requests.

Is GPT Image 1 cheaper than GPT Image 1.5?

No. GPT Image 1.5 is actually cheaper ($0.013/image on EvoLink vs $0.034 for GPT Image 1). GPT Image 1 is better suited for editing workflows and async batch processing, while GPT Image 1.5 is optimized for fast synchronous generation.

Does GPT Image 1 support image editing?

Yes. GPT Image 1 supports mask-based inpainting where you specify which regions to regenerate. This makes it suitable for background removal, object replacement, and targeted image modifications.

How do I access GPT Image 1 API?

Can I use GPT Image 1 generated images commercially?

Yes. Images generated through the API come with full commercial usage rights. You retain ownership of all generated content.
