Language: English

GPT Image 1.5 is OpenAI’s high-fidelity image generation model for prompts that specify composition, lighting, exact copy and several interacting constraints. Low, Medium and High are separate visible billing tiers, and transparent output can be requested directly.

## Model details

- Developer: OpenAI
- Status on All Image AI: Active
- Last verified: 2026-08-25
- Maximum output: 1K
- Modes: Text to Image, Typography
- Reference images: not supported
- Resolutions: 1K
- Aspect ratios: 1:1, 3:2, 2:3

## Best for

- Long instruction-rich briefs
- Readable display text
- Transparent creative assets
- Precise composition and lighting

## How to use

1. Write the brief as clear sentences.
2. Quote every required word.
3. Draft at Low or Medium.
4. Use High only for the selected final.

## Settings explained

### Quality

Low is for composition drafts, Medium is the balanced default, and High spends much more for final detail.

### Background

Transparent requests an alpha channel; Opaque guarantees a filled canvas.

## Prompt examples

### Historical scene

> Realistic handheld phone photograph from the deck of an early twentieth-century ocean liner at night, cold mist, period-correct clothing, physically plausible lighting

### Transparent mark

> Playful enamel camping badge reading “NORTH / 27”, crisp lettering, pine and moon motif, isolated with a transparent background

## Limitations

- Token usage makes the exact upstream cost variable
- High quality is substantially more expensive
- This page exposes generation, not image editing

## Pricing and credits

Credits for one image at default quality and mode. Resolution, quality, reference inputs, edit mode and output count can change the total. Check the Generate button before submitting.

| Resolution | Credits / image |
| --- | --- |
| 1K | 7 |

Failed generations cost 0 credits. Catalog availability does not guarantee runtime availability; the workspace reports whether the selected model can run.

## Frequently asked questions

### Why can the provider cost vary?

Prompt tokens, reasoning text tokens, quality and aspect ratio all contribute to the upstream bill.
