ChatGPT Images 2.5 cuts latency by up to 50%

OpenAI released ChatGPT Images 2.5, claiming up to 50% lower image-generation latency than Images 2.0 and adding Sketch, area comments, templates, and two API models, according to The Verge’s rollout report and 9to5Mac’s summary. Builders with image SLOs should benchmark Flare and Sunburst on edit-heavy prompts before changing budgets or latency targets, because 50% is a vendor ceiling rather than an independent p95. That keeps the archive’s image-rollback trust lesson in view.
