## Direct answer

GPT Image 2 is the best default choice on GPT Image Hub when you need high-quality generation or editing, many aspect-ratio choices, and up to 16 reference images. Use it for polished commercial visuals, product mockups, editorial assets, and prompts where instruction following matters more than the lowest possible iteration latency.

## Model facts

- Official model ID: gpt-image-2
- Provider: OpenAI
- Hub quality tiers: 1K, 2K, 4K
- Reference images: Up to 16
- Cost per image: 5–570 credits (≈ $0.005–$0.569 at the Plus pack rate); pricing: https://www.gptimagehub.com/pricing

## Best use cases

- Product renders, ad concepts, campaign key visuals, thumbnails, and social creatives.
- Image edits that need several reference inputs or consistent brand/style constraints.
- 4K exports in GPT Image Hub when a larger final image is required.
- Structured prompts with detailed composition, typography, lighting, and camera direction.

## Where to be careful

- Transparent background requirements, because OpenAI's current GPT Image 2 guide says transparent backgrounds are not supported for this model.
- Very rough brainstorming where the fastest low-cost draft is more important than output polish.
- Prompts that depend on Gemini-specific multimodal reasoning or Google ecosystem examples.

## Prompting guidance

- Write the scene first, then specify camera, lighting, material, palette, text, and output format.
- For reference-image workflows, state exactly what to preserve and what can change.
- Use 1K for quick drafts, then move to 2K or 4K only when the composition is approved.
- Keep on-image text short and quote it explicitly.

## Example prompts

```text
Create a 4K hero image for a premium skincare serum on warm marble, soft morning window light, dewy reflections, minimal beige packaging, blank space on the right for headline text, editorial product photography.
```

```text
Use the reference images as brand style anchors. Generate a square app launch graphic with the same color system and lighting, but replace the subject with a floating glass camera icon over a dark studio background.
```

```text
Design a cinematic poster for an AI image prompt library, centered desktop workspace, glowing generated images on screen, realistic reflections, no extra text except "GPT Image Hub".
```

## FAQ

### Is GPT Image 2 the default model on GPT Image Hub?

Yes. GPT Image Hub uses GPT Image 2 as the default image model because it covers the broadest set of quality tiers, aspect ratios, and reference-image workflows in the current app configuration.

### Does GPT Image 2 support 4K output here?

GPT Image Hub exposes 4K as an available quality tier for GPT Image 2. Use it for final exports rather than every draft, because higher resolution usually increases latency and cost.

### Can GPT Image 2 create transparent backgrounds?

OpenAI's current image generation guide says gpt-image-2 does not support transparent backgrounds, so prompts that require transparent PNG assets should be planned accordingly.
