ChatGPT Images 2.5 Launches Faster With Sketch Tool

OpenAI has launched ChatGPT Images 2.5, an upgrade delivering up to 50% faster image generation, more natural lighting, richer textures, and better instruction-following across multiple edits. A new Sketch feature lets users draw rough layouts as visual references, while improved detail preservation ensures targeted edits don't degrade surrounding elements. The update introduces two model variants: GPT-Image-2.5 Flare, optimized for speed and transparent backgrounds, and GPT-Image-2.5 Sunburst, prioritizing precision for pixel-perfect results. New templates, inline image comments, and prompt sharing are also included. The model features C2PA metadata and invisible watermarking to prevent deepfakes and unauthorized reuse.
