## A faster, sharper ChatGPT image model

gpt-image-1.5 builds on the native multimodal architecture of its predecessor — text and images processed together in a unified neural network — but delivers the output 4× faster at 20% lower cost. The most visible improvements are in editing precision and small text rendering. Edits now preserve lighting, composition, likeness, and appearance while applying changes exactly as instructed.

All the world-knowledge grounding from GPT-4o carries over: accurate depictions of logos, flags, landmarks, scientific diagrams, and knowledge-rich infographics.

## Prompting tips

* **Name real-world subjects directly** — "A poster celebrating the Apollo 11 mission, with an accurate depiction of the lunar module" leverages GPT-4o's world knowledge for accuracy.
* **Use it for infographic copy** — Dense, labeled infographics with specific text content render cleanly. Describe exact headings, labels, and callout text you want.
* **For editing, be specific about what stays** — "Change the background to a forest but keep the subject's lighting, pose, and outfit exactly as-is."

### Example prompts

> A detailed infographic explaining photosynthesis with labeled diagrams, clean white background, educational illustration style, accurate scientific labels.

> A World War II era propaganda poster aesthetic with bold typography reading "INNOVATION NEVER SLEEPS", dark navy and gold, vintage texture.

> A modern smartphone mockup showing a fitness app dashboard with charts, clean UI design, soft shadow.
