> Published 2026-04-05, updated 2026-09-05 · https://www.promptzone.com/seren_whitaker/openai-launches-image-4o-for-smarter-image-generation-1cll

OpenAI has unveiled Image 4o, a cutting-edge model for generating high-quality images from text prompts, promising double the speed of previous versions while maintaining accuracy.

> **Model:** Image 4o | **Parameters:** 5B | **Speed:** 1.5 seconds per image 
> **Price:** $0.002 per image | **Available:** OpenAI API | **License:** Proprietary

### Key Features of Image 4o 
Image 4o introduces advanced capabilities like improved handling of complex prompts, achieving 95% accuracy in style consistency tests. For instance, it generates images with finer details, such as realistic textures in landscapes, based on benchmarks showing a 30% reduction in artifacts compared to DALL-E 3. Early testers report that the model excels in creative tasks, like producing photorealistic outputs from vague descriptions, with processing times under 2 seconds. 

> **Bottom line:** Image 4o delivers faster, more reliable image creation, making it ideal for developers needing quick iterations.

### Performance Benchmarks and Comparisons 
In recent tests, Image 4o scored 850 on the ImageNet benchmark, surpassing DALL-E 3's 820 by handling higher resolution outputs up to 1024x1024 pixels. Here's a quick comparison of key metrics:

| Feature | Image 4o | DALL-E 3 |
|------------------|----------------|----------------|
| Speed (per image) | 1.5 seconds | 3 seconds |
| Artifact Rate | 5% | 7% |
| Resolution Max | 1024x1024 | 512x512 |
| Cost per Image | $0.002 | $0.004 |

Users note that these improvements stem from optimized neural architecture, reducing VRAM usage to 8GB during generation.
