Would you use new AI tools like image-generating sketch features in your own creative projects?

OpenAI has officially launched ChatGPT Images 2.5, a model update featuring new design tools and a 50 percent reduction in generation latency compared to Images 2.0. The release is currently available across web, desktop, and mobile platforms.

Why it matters

By integrating specific design-focused features like templates and sketch-based references, OpenAI is shifting its image generation capabilities toward more structured professional workflows. These additions streamline the transition from initial conceptual drawings to final product assets.

The new model achieves a 50 percent decrease in generation latency compared to the previous version. Beyond speed gains, the platform added a drawing-based reference tool and template library.

The players

OpenAI

An AI research organization focused on the development of large language models and generative visual platforms.

The details

The update introduces a Sketch feature, accessed by typing @sketch in the composer, which allows users to create hand-drawn references that the model uses to guide image generation. Additionally, the platform now supports prompt sharing, enabling users to copy and re-use the exact instructional text used for specific image outputs. For commercial and professional use cases, new templates were integrated to assist in the rapid production of flyers and product images.

The Tech Race

This release marks a direct performance iteration over the ChatGPT Images 2.0 model, focusing on reduced latency as a core metric for user experience. It follows the industry trend of shifting from purely prompt-based image generation toward more structured, reference-heavy workflows.

Users can immediately access the new sketch tools and templates on web, desktop, and mobile platforms. The faster generation speeds are now active, though API developers must specifically transition to the new GPT-Image-2.5 Flare or GPT-Image-2.5 Sunburst models for their own integrations.

The takeaway

OpenAI is evolving its image suite from a text-to-image engine into a collaborative design tool. Users should monitor the rollout of future model updates to determine if these specific template types will expand to include more industry-specific design formats.
