On September 8, 2026, OpenAI released ChatGPT Images 2.5 with a new Sketch feature that lets users type @Sketch, draw a rough doodle inside the chat, add a natural-language description, and receive an AI-generated image that blends the sketch with the instructions, allowing inline edits and up to 50 % faster generation.
Short answer: On September 8, 2026, OpenAI released ChatGPT Images 2.5 with a new Sketch feature that lets users type @Sketch, draw a rough doodle inside the chat, add a natural-language description, and receive an AI-generated image that blends the sketch with the instructions, allowing inline edits and up to 50 % faster generation.
OpenAI unveiled ChatGPT Images 2.5 on Tuesday, September 8, 2026, introducing a fresh way to guide the model’s picture-making abilities. The new Sketch feature lets users draw a rough doodle directly inside the chat interface and then describe how they want the AI to turn that scribble into a polished image. To start, you type @Sketch in the message box, which opens a small canvas where you can sketch with a mouse, touchpad or finger. After you finish the drawing, you add a natural-language prompt describing the desired style, lighting or details, and the model generates an image that blends your doodle with your instructions.
In a quick test, the reporter drew a clumsy cat outline with a computer mouse and asked the system to produce a realistic photograph. The result was a convincing cat image that matched the requested pose and fur texture. The tool also allows you to click on specific parts of the generated picture and leave a comment requesting a change. In the example, the reporter first asked for green eyes, then later edited the comment to ask for blue eyes, and the model updated the eyes accordingly without needing to regenerate the whole scene.
OpenAI claims that the underlying image model, ChatGPT Images 2.5, delivers several upgrades over the previous version. Lighting appears more natural, surfaces show richer texture, and the model follows multi-step editing requests more reliably. Perhaps most noticeable for developers is the latency improvement; the company says image generation is up to fifty percent faster than with Images 2.0. These changes aim to make the workflow smoother for anyone who needs rapid visual feedback, from designers prototyping concepts to educators illustrating ideas.
The rollout covers all major platforms where ChatGPT is available. Users of the standard ChatGPT service, the professional ChatGPT Work tier, and the Codex coding assistant can access Sketch and the upgraded image model on desktop browsers, mobile apps and the web interface. No additional software installation is required; the feature appears automatically once the update is applied to your account.
For builders who rely on AI-generated visuals, the ability to start with a hand-drawn cue lowers the barrier to expressing vague ideas. Instead of struggling to articulate a complex scene in words alone, you can lay down a quick shape and let the model fill in the details. This can speed up brainstorming sessions, reduce the number of revision cycles, and make it easier to explore variations on a concept by simply tweaking the sketch or the accompanying comment.
The introduction of Sketch also hints at a broader trend toward multimodal interaction within conversational AI. By accepting visual input directly in the chat, OpenAI is moving the model closer to acting as a collaborative design partner rather than a pure text-to-image tool. As the feature settles into everyday use, developers may want to experiment with how doodle-based prompts affect output quality, test the limits of the model’s interpretive ability, and consider integrating similar sketch-first workflows into their own applications. Keeping an eye on latency reports and user feedback will help determine whether the promised speed gains hold up under real-world loads.

ChatGPT Images 2.5 delivers more natural lighting, richer surface texture, better reliability with multi-step editing requests, and up to fifty percent faster image generation compared with Images 2.0.
Yes-you can click on any part of the generated picture, leave a comment requesting a change, and the model will update only that area (e.g., eye color) without needing to regenerate the whole scene.

On September 8, 2026, OpenAI released ChatGPT Images 2.5, adding a Sketch feature that lets users draw a rough doodle in a pop-up canvas via @Sketch, then describe style or details to generate a polished AI image.
OpenAI announced on September 8 2026 that its researchers solved the Navier-Stokes equation using an internal AI system more capable than GPT-6 Astra, aided by ten thousand simultaneous processing agents; the claim is contested by allegations that the model may have benefited from user data in Codex sessions.
OpenAI unveiled ChatGPT Images 2.5 on September 8, 2026, delivering noticeably sharper details, richer textures and more natural lighting while cutting generation latency by up to 50 % versus Images 2.0. It also retains core subjects from reference images more reliably and allows precise edits that keep earlier changes intact.
