# GPT Image 2

> OpenAI GPT Image 2 image generation model. Next-generation autoregressive + reasoning hybrid model with flexible resolution up to 4K and near-perfect text rendering.

GPT Image 2 is OpenAI's next-generation image generation model, available through Upmore API. Built on an autoregressive + reasoning hybrid architecture, it delivers native 2K resolution, near-perfect text rendering (\~99% character-level accuracy across 12+ languages), and superior multi-object scene composition.

## Key capabilities

* **Text-to-Image** — Generate images from natural language descriptions
* **Flexible resolution** — Any custom size up to 4K (3840px), edges must be multiples of 16
* **Near-perfect text rendering** — \~99% character-level accuracy across 12+ languages
* **Multi-object composition** — Complex scenes without occlusion or misplacement issues
* **Multi-style** — Photorealism, illustration, anime, vector, 3D, data visualization
* **Batch generation** — Generate up to 4 images per request
