OpenAI has launched a significant upgrade to its image generation capabilities, directly challenging Google’s rapidly popular Gemini 2.5 Flash Image, nicknamed “Nano Banana.” The update, dubbed GPT Image 1.5, is now available within ChatGPT Images and via the OpenAI API. This move comes amid reports of internal pressure at OpenAI following Google’s recent AI advancements, signaling a renewed competitive push.
The Race for AI Supremacy
The AI landscape is heating up. Google’s Nano Banana has quickly gained traction due to its speed and ease of use, becoming integrated into Gemini, Google Photos, Search, and Messages. OpenAI’s response isn’t just an upgrade; it’s an attempt to reclaim momentum. The new ChatGPT Images promises faster generation speeds (up to 4x faster), more accurate edits, and better adherence to user instructions.
This rivalry matters because AI image generation is becoming a core feature of everyday tools. From social media content creation to professional design workflows, these technologies are reshaping how visuals are made and consumed. The competition between OpenAI and Google will drive innovation and accessibility in this field.
GPT Image 1.5: What’s New?
The core improvements focus on reliability and precision. OpenAI claims the new model will produce more consistent results across multiple outputs, addressing a common issue in previous AI image generators. The update also introduces a dedicated “Images” tab within ChatGPT, designed to inspire creativity and streamline the image creation process.
Real-world tests show GPT Image 1.5 immediately topping LMArena’s Text-to-Image leaderboard, surpassing Nano Banana Pro. However, side-by-side comparisons reveal a nuanced picture. In practical applications, such as editing a photo from nighttime to daytime, Google’s Nano Banana appears to deliver slightly more polished results, at least based on initial observations.
How to Access the New Features
The update is rolling out now for all ChatGPT users. Simply navigate to the “Images” tab at chatgpt.com/images to begin experimenting. Free users will face limitations, while developers can access the GPT Image 1.5 model through the OpenAI API. Pricing details are available on the OpenAI website.
The launch of GPT Image 1.5 demonstrates OpenAI’s commitment to staying competitive in the fast-moving AI space. While Nano Banana currently holds an edge in user experience, OpenAI’s rapid response signals a long-term battle for dominance in AI-powered image generation.
The future of visual content creation is being written now, and OpenAI is determined to be a major player.
