Gemini 2.5 Flash: Google's AI Image Editor Is Now Available In Full
Google, Monday, October 6th, 2025
Google has rolled out Gemini 2.5 Flash, its advanced AI image editing model, making the tool widely available. Its native image generator app, Nano Banana, now has 10 new aspect ratios and the option for image-only output.
Aspect ratios enable AI-generated images to be created with the ideal shape for various uses, such as vertical social media posts or sweeping landscape shots. Gemini 2.5 Flash Image now supports landscape (21:9, 16:9, 4:3, 3:2), square (1:1), portrait (9:16, 3:4, 2:3), and 'flexible' (5:4, 4:5) aspect ratios.
The other new feature is the ability to specify image-only output. The model defaults to returning text and image responses, where a text explanation accompanies the image output, but this can be overwritten by replacing response_modalities=''Text', 'Image'' with response_modalities=''Image''.
