OpenAI has launched GPT Image 1.5, a new flagship image generation model integrated into ChatGPT Images, optimized for both creating images from scratch and precise photo editing. This model produces outputs that closely match user intent, preserving important details like lighting, composition, and appearances while making only requested changes. It generates images up to 4x faster than its predecessor, reflecting improved hardware efficiency and lower operational costs. GPT Image 1.5 is available to all ChatGPT users and through an API priced 20% lower than the previous model, with Business and Enterprise access coming later.
Key Features and Improvements
- Precise Edits: The model reliably adheres to user instructions, enabling practical edits such as resizing without unwanted changes (e.g., preserving logos), believable clothing and hairstyle try-ons, and stylistic or conceptual transformations that maintain the original image's essence.
- Multi-step Editing: GPT Image 1.5 can handle complex tasks like combining objects from multiple drawings into one image and altering their illustration styles.
- Text Rendering: Enhanced ability to render small, dense text makes it suitable for generating infographics, a notable improvement inspired by Google’s Nano Banana Pro model.
- Speed and Efficiency: The model’s faster generation is due to reduced hardware requirements, which also lowers electricity consumption and costs.
- API Access: Developers can integrate GPT Image 1.5 via an API with reduced pricing, while nontechnical users interact through ChatGPT’s image generation feature.
- User Interface: A new ChatGPT section offers pre-configured image filters and prompt suggestions, designed to enhance creative exploration and inspiration.
Limitations and Context
- GPT Image 1.5 has limited support for some drawing styles and occasionally makes errors in images requiring scientific knowledge, though it performs better than its predecessor in these areas.
- The release follows OpenAI’s upgrade to GPT-5.2, a foundation model that excels in scientific tasks and recently set a record on a college-level math benchmark.
Overall, GPT Image 1.5 positions ChatGPT as a versatile creative tool, capable of both detailed practical edits and expressive image generation, with improved speed, accuracy, and cost efficiency.
