■ AI-SUMMARIZED FROM 3 SOURCES ▸ TIMELINE

OpenAI launched ChatGPT Images 2.5, delivering up to 50% faster image generation compared to its predecessor. The update also introduces a Sketch feature that lets users draw directly within ChatGPT.

The new model addresses a key limitation of AI image generators: speed. OpenAI claims the performance improvement cuts latency by half, making the tool more practical for rapid iteration and creative workflows. The Sketch feature represents a notable interface change. Users can now hand-draw compositions or concepts within ChatGPT, then have the model generate refined images based on those inputs. This bridges manual design work with AI generation capabilities. The release marks OpenAI's continued investment in its image generation capabilities, directly competing with rival services like Midjourney and Stable Diffusion. Faster processing times could appeal to professionals and casual users alike who depend on quick turnarounds for content creation. OpenAI shared the update first with Axios, with the launch occurring Tuesday.
