Key Capabilities of GPT Image 1

A deep dive into the technical strengths of the model accessible via our platform.

Flexibility

Three Quality Tiers

Choose from low (0.26×), medium (1×), or high (3.91×) quality settings to balance speed, cost, and output quality for your specific use case.

Versatility

Multiple Size Options

Generate square (1:1), portrait (2:3), or landscape (3:2) images. Non-square sizes have a 1.47× multiplier for transparent pricing.

Efficiency

Batch Generation

Generate up to 10 images in a single request with the n parameter. Total cost scales linearly for predictable billing.

Power

Reference Image Support

Upload up to 16 reference images (50MB each) for image-to-image and editing tasks. Supports JPEG, PNG, and WebP formats.

Architecture

Async Processing

Asynchronous task handling with progress tracking. Query task status and retrieve results when ready for optimal UX.

Legal

Commercial Licensing

Images generated via the GPT Image 1 API come with full commercial usage rights, allowing you to monetize the content without legal concerns.

Frequently Asked Questions

Everything you need to know about the product and billing.

The GPT Image 1 API is a versatile image generation service that supports text-to-image, image-to-image, and image editing modes. It offers flexible quality (low/medium/high) and size (square/portrait/landscape) options with transparent pricing multipliers. evolink.ai integrates this model to provide developers with a stable, high-performance interface for commercial applications.

Pricing follows a transparent multiplier system: Base price × Quality multiplier × Size multiplier × Count (n). Quality multipliers are: low (0.26×), medium (1×), high (3.91×). Size multipliers are: square (1×), non-square (1.47×). This allows you to optimize costs based on your specific needs.

Yes, absolutely. You retain full ownership and commercial rights to all images generated using the GPT Image 1 API. This means you can use the artwork for digital ads, physical merchandise, game assets, and website content without paying royalties.

The API supports both aspect ratio format (1:1, 2:3, 3:2) and pixel format (1024x1024, 1024x1536, 1536x1024). Output images are delivered as URLs valid for 24 hours. Reference images can be JPEG, PNG, or WebP format, up to 50MB each.

You can generate 1 to 10 images in a single request using the n parameter. Each additional image costs the same as the first, making batch generation cost-effective for bulk use cases.

You can upload up to 16 reference images per request using the image_urls parameter. These images are used for image-to-image transformation and editing tasks. URLs must be directly accessible by the server and support JPEG, JPG, PNG, and WebP formats.

Choose based on your use case: Low quality (0.26× cost) for fast prototyping and previews, Medium quality (1× cost) for standard production use, High quality (3.91× cost) for premium outputs requiring maximum detail and fidelity.

When you submit a request, you receive a task ID immediately. Use this ID to poll the /v1/tasks/{task_id} endpoint to check progress and retrieve results when the task completes. This architecture allows your application to handle long-running generations gracefully.
