What Is ChatGPT Image Generation?
ChatGPT image generation is OpenAI's built-in feature that creates images from text prompts directly inside ChatGPT. Powered by GPT Image 2 (launched April 2026), it uses an autoregressive model with reasoning capabilities — a major leap from earlier DALL-E diffusion models. GPT Image 2 delivers near-perfect text rendering, multilingual support, and photorealistic output at up to 2K resolution.
Thinking Mode — Reasons Before Drawing
GPT Image 2 introduces a Thinking mode that analyzes your prompt, breaks down the task, plans composition, and self-verifies the output before delivering. It checks text spelling, object placement, and style consistency — then corrects errors automatically.
Accurate Text & Multilingual Support
GPT Image 2 solved the text-rendering problem that plagued DALL-E. Signs, labels, posters, and menus now render correctly — in English, Chinese, Japanese, Korean, Hindi, and more.
Instant & Thinking — Two Modes
Instant mode generates fast for simple requests. Thinking mode activates reasoning for complex scenes, multi-element layouts, and precise text — delivering higher quality at the cost of speed.
Image Arena #1 — Nano Banana 2 is #2
GPT Image 2 ranks #1 across all three Image Arena categories. Nano Banana 2 (available on nana img) ranks #2 — the closest competitor with an ELO gap of just 42.5 points.
