OpenAI Releases ChatGPT Images 2.5 With Sketch Input and Two New API Models

OpenAI has launched ChatGPT Images 2.5, an updated image generation system that introduces a Sketch feature allowing users to convert rough hand-drawn inputs into detailed AI-generated images. Two new API models accompany the release, giving developers programmatic access to the upgraded generation capabilities. The Sketch feature lowers the barrier for creative ideation workflows, enabling non-designers to communicate visual intent through freeform drawing rather than text prompts alone. For developers building image-generation pipelines, design tools, or multimodal applications, the new API models are immediately actionable. This update positions OpenAI's image stack as more interactive and accessible, directly competing with iterative design tools in the creative software space.
