**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`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/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`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/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.

```javascript
// 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`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/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`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/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`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/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.
