# GPT Image 2.5: generation
|
|
|
|
Read for new photos, illustrations or product scenes. For existing-image changes,
|
|
use [editing](openai-image-2.5-editing.md) instead. Source check: **2026-09-09**;
|
|
[provenance and validation boundary](openai-image-2.5.md#source-boundaries).
|
|
|
|
## Official examples to consult selectively
|
|
|
|
- [Style and lighting](https://developers.openai.com/api/docs/guides/image-prompting?model=gpt-image-2.5#control-style-and-lighting)
|
|
- [Historical and real-world context](https://developers.openai.com/api/docs/guides/image-prompting?model=gpt-image-2.5#use-historical-and-real-world-context)
|
|
- [Reusable logos](https://developers.openai.com/api/docs/guides/image-prompting?model=gpt-image-2.5#design-a-reusable-logo)
|
|
|
|
Open only the matching example, not the whole guide. Camera specifications are
|
|
appearance cues, not exact physical simulation. The examples do not establish
|
|
which variant will win on the user's brief.
|
|
|
|
## Local workflow using the existing gallery and craft
|
|
|
|
These are repo application notes, not locally measured 2.5 performance claims.
|
|
Start from the user's brief; consult a gallery case only for missing inspiration.
|
|
Do not append every possible quality adjective.
|
|
|
|
| Deliverable | Resolve before generation | Inspect in the actual output |
|
|
|---|---|---|
|
|
| Natural photograph | Subject/action, framing, light direction, texture and retouching limits | Skin, hands, contact shadows, reflections and background perspective |
|
|
| Product scene | Product features, placement, materials, scene palette, required label copy | Geometry, label spelling, reflections and contact with the surface |
|
|
| Illustration | Medium, shape language, composition, palette and intended use | Consistent medium, silhouette readability, unwanted photorealism |
|
|
| Logo concept | Approved name, symbol, use size and background | Spelling and small-size legibility; a raster concept is not editable vector artwork |
|
|
|
|
If a capture/material question remains, consult the relevant section (8, 10 or 12)
|
|
of [craft.md](craft.md), not the full file. For type-led deliverables, switch to
|
|
[layout and text](openai-image-2.5-layout-and-text.md). If a reusable portrait
|
|
starting point is needed, see the **Natural editorial photograph** section of
|
|
[community templates](templates-gpt-image-2.5.md), retaining its source label.
|
|
|
|
## Before calling the CLI
|
|
|
|
- Resolve factual details from the brief; do not inherit dates or claims from a
|
|
historical gallery example.
|
|
- Use the confirmed model and settings. Description words such as “4K” do not
|
|
set API dimensions; check [models.md](models.md#parameters).
|
|
- Do not add a reference-identity promise to text-only generation. Attach the
|
|
relevant input and follow the editing slice when identity must be preserved.
|
|
- State the failed visual requirement before proposing a paid refinement;
|
|
request permission rather than automatically increasing quality or switching models.
