GPT Image-2 API overview

GPT Image-2 is an image generation model for creating visuals from text prompts or transforming images with reference inputs. On UniAll AI, the public model ID is `gpt-image-2-origin`.

It supports common production workflows such as marketing creatives, product posters, concept art, social media visuals, reference-guided image generation, and automated image pipelines.

Key capabilities

• **Text to image**: generate images from a prompt.
• **Image to image**: use one or more reference images with a prompt.
• **Reference images**: upload PNG, JPEG, or WebP references.
• **Aspect ratios**: `1:1`, `16:9`, `9:16`, `4:3`, `3:4`, `3:2`, `2:3`, `4:5`.
• **Resolution tiers**: `1K`, `2K`, and `4K`.
• **Async API**: requests are submitted asynchronously for generation jobs.

GPT Image-2 API pricing

GPT Image-2 is billed per generated image. Pricing depends on the selected resolution tier:

| Resolution | Price per image | |---|---:| | 1K | $0.01836 | | 2K | $0.05576 | | 4K | $0.11424 |

The default listed price is **$0.01836 per image** for 1K output. If you request multiple images, the total cost scales with `num_images` and the selected `resolution`.

UniAll AI supports refund on failure and retry on failure for this model, with up to 2 failure retries.

Who should use GPT Image-2?

GPT Image-2 is suitable for:

• Developers building AI image generation into apps or workflows.
• Marketing teams producing campaign and social media assets.
• E-commerce teams creating product-style visuals and posters.
• Design teams exploring visual directions from prompts or references.
• Automation teams that need API-based text-to-image or image-to-image generation.

API usage

Endpoint:

```http POST /v1/images/generations ```

Example request body:

```json { "model": "gpt-image-2-origin", "generation_mode": "image_to_image", "image_url": ["https://example.com/reference-1.png"], "prompt": "A premium product poster with clean lighting and sharp details.", "aspect_ratio": "1:1", "resolution": "1K", "num_images": 1 } ```

For text-to-image generation, use `generation_mode: "text_to_image"` and provide a `prompt`. For image-to-image generation, provide both `prompt` and `image_url`.

Pricing guidance

Choose `1K` for drafts, thumbnails, and high-volume testing. Use `2K` when you need sharper production assets. Select `4K` for high-detail outputs, print-oriented concepts, or premium visual work where resolution matters more than cost.

Because billing is per output image, you can control spend by lowering `num_images`, testing prompts at `1K`, and only moving final prompts to higher resolution tiers.
