ChatGPT Picture Generator: Conversational Image Creation
What Is the ChatGPT Picture Generator?
OpenAI has officially retired DALL-E 3 as of March 4, 2026, and it is no longer available for new deployments. The DALL-E 3 API was fully deprecated on May 12, 2026. In its place, OpenAI introduced GPT Image 2 (gpt-image-2) in April 2026. Unlike DALL-E's diffusion-based approach, GPT Image 2 uses an autoregressive model that generates images similarly to how LLMs generate text. This new model features advanced photorealism, precise instruction following, and image editing capabilities.
Free users on ChatGPT can still generate images with a daily quota, while Plus subscribers enjoy higher resolution and faster generation speeds. The model now understands multi-turn conversations, allowing you to iteratively refine an image by simply chatting—no need to rewrite the entire prompt.
