GPT Image 2 — OpenAI's Most Capable Image Model, Now on Sider

GPT Image 2 is OpenAI's latest image generation model, released in April 2026. It features a reasoning layer that analyzes prompt structure before generating, supports up to 2K resolution, renders text in multiple languages with high accuracy, and can generate up to 8 consistent images from a single prompt.

GPT Image 2 uses an autoregressive architecture instead of DALL-E 3's diffusion approach, resulting in significantly better text rendering, stronger attribute binding (15–20 objects vs. 5–8), and the ability to reason through image structure before generating. It also supports higher resolution (2K) and wider aspect ratios.

Install the Sider extension for Chrome or Edge, click the Creator tab, open the image generation page, and select gpt-image-2 from the model list. Enter your prompt and generate. You can also compare outputs with other models like Nano Banana Pro side by side.

Sider provides access to 10+ image generation models including GPT Image 2, Nano Banana Pro, and more. You can run the same prompt across multiple models and compare results to find the best output for your needs.

Yes. GPT Image 2 is a major step forward in text rendering. It handles English and Latin scripts with near-perfect accuracy and has made significant gains in Japanese, Korean, Chinese, Hindi, and Bengali as well.

GPT Image 2 supports up to 2K resolution with a wide range of aspect ratios from 3:1 (wide) to 1:3 (tall), covering formats suitable for social media, print, cinema, and more.
