Feature Drop: GPT-Image-1.5 and Nano Banana 2 Image Models Now Available

GPT-Image-1.5 and Nano Banana 2 are now available in Omnifact. GPT-Image-1.5 delivers better image quality than GPT-Image-1 while reducing generation cost, and you can use it for both image creation and image editing workflows in chat. In addition, we are expanding our Google image generation options with the new Nano Banana 2 model which replaces Nano Banana Pro as Google's newest image generation model.

What Changes for Your Team

Before this update, teams that wanted to stay on OpenAI image generation had one GPT-Image option in Omnifact. Now you can choose between GPT-Image-1 and GPT-Image-1.5, with v1.5 positioned as the stronger value option for quality and cost. Additionally, teams using Google models now have access to Nano Banana 2 for expanded visual styles and creative capabilities.

This helps teams test prompts across model versions, compare results side by side, and decide which models to keep as their default.
