GPT-Image-2 Resolutions Pricing: Complete 2024 Cost Guide

GPT-Image-2 resolutions pricing ranges from $0.010625 to $0.02625 per credit depending on output resolution, with three standardized tiers at 1K, 2K, and 4K.

The freestylefly/awesome-gpt-image-2 repository contains the definitive pricing configuration for OpenAI's GPT-Image-2 model, implemented within an APIMart billing system. According to the source code analysis, resolution-specific costs are hardcoded in the test suite that validates the live pricing endpoint.

Resolution-Based Pricing Tiers

GPT-Image-2 uses a three-tier pricing structure based on output resolution, defined in shared/apimart.test.js. Each tier represents the approximate pixel dimensions of the generated image and carries a distinct per-credit cost.

• 1K Resolution (≈1024 px): $0.010625 per credit
• 2K Resolution (≈2048 px): $0.0175 per credit
• 4K Resolution (≈4096 px): $0.02625 per credit

These values are stored in the resolution_prices object within the APIMart pricing test suite. The pricing scales progressively with resolution, with 4K generation costing approximately 2.47x more than 1K output.

Implementation in the Source Code

The pricing configuration resides in shared/apimart.test.js, where the resolution_prices dictionary maps resolution keys to USD values. This configuration mirrors the live pricing logic served by the /api/apimart/pricing endpoint.

// From shared/apimart.test.js
resolution_prices: { 
  '1K': 0.010625, 
  '2K': 0.0175, 
  '4K': 0.02625 
}

The repository uses this test configuration to validate that the billing system correctly calculates generation costs before deployment. When a user requests an image at a specific resolution, the system multiplies the base credit cost by the appropriate multiplier from this configuration.

Cost Calculation Examples

To calculate the total cost of a generation request, multiply the resolution base price by the number of credits consumed. For example, generating a single 2K image that consumes 10 credits would cost:

$0.0175 × 10 = $0.175 per image

Note that the repository also contains a separate $5 / 300 credits catalog entry for other services, but this flat-rate pricing does not apply to GPT-Image-2's resolution-specific billing model. The resolution-based pricing always takes precedence for image generation calls.

Summary

• 1K resolution costs $0.010625 per credit according to shared/apimart.test.js
• 2K resolution costs $0.0175 per credit, suitable for standard high-quality outputs
• 4K resolution costs $0.02625 per credit for maximum detail generation
• Pricing is implemented via the resolution_prices object in the APIMart test suite
• The /api/apimart/pricing endpoint serves these values to the production billing system

Frequently Asked Questions

How much does it cost to generate a 4K image with GPT-Image-2?

A 4K resolution image costs $0.02625 per credit according to the APIMart pricing configuration in shared/apimart.test.js. The total cost depends on how many credits the specific generation consumes, which varies based on complexity and quality settings.

Where is the GPT-Image-2 pricing defined in the repository?

The pricing is defined in shared/apimart.test.js within the resolution_prices object. This test file validates the pricing logic that powers the /api/apimart/pricing endpoint, ensuring the live system charges correctly for 1K, 2K, and 4K resolutions.

Is there a flat-rate pricing option for GPT-Image-2 credits?

No. While the repository contains a $5 / 300 credits entry for other services, GPT-Image-2 specifically uses resolution-based pricing. You pay different per-credit rates ($0.010625 to $0.02625) depending on whether you select 1K, 2K, or 4K output resolution.

How do I calculate the total cost for a batch of images?

Multiply the per-credit price of your chosen resolution by the number of credits consumed per image, then multiply by the batch size. For example, ten 2K images consuming 5 credits each would cost: $0.0175 × 5 × 10 = $0.875 total.
