Model Performance - GPT Image 1.5 demonstrates enhanced instruction adherence, precise image editing, and retains details better than its predecessor, with a generation speed four times faster [8]. - The pricing for GPT Image 1.5 has been reduced by 20%, allowing users to generate more images within the same budget. High-quality 1MP images cost approximately $133 per thousand, while low-quality images are priced at $9 per thousand [8]. - In competitive assessments, GPT Image 1.5 ranked first in both text-to-image and image editing functionalities, surpassing Nano Banana Pro by 46 points in text-to-image and 4 points in image editing [8]. User Experience and Feedback - User tests reveal that GPT Image 1.5 excels in image quality and adherence to prompts but struggles with Chinese language support, leading to frequent text errors [11][12]. - Nano Banana Pro, while accurate in text output, has issues with following composition instructions, indicating a trade-off between text accuracy and adherence to visual prompts [15]. - Overall aesthetic preferences lean towards GPT Image 1.5, but Nano Banana Pro is favored for its accuracy and better support for Chinese text [17]. Industry Context - The competition between OpenAI and Google has intensified, with Google's Gemini 3 series posing significant challenges to OpenAI's dominance in the large model space [27]. - User expectations have risen due to Google's advancements, and while GPT Image 1.5 shows competitive scores, it has not fully met user expectations, particularly regarding realism and the absence of "AI flavor" in images [27].
