According to OpenAI on X, ChatGPT Images 2.0 now supports aspect ratios as wide as 3:1 and as tall as 1:3, enabling generation-ready outputs for wide banners, presentation slides, posters, and social graphics. As reported by OpenAI, this expands creative control and reduces post-production cropping, offering marketers and design teams faster asset creation for ad variants, A/B testing, and localized campaigns.
