GPT Image 1.5 is OpenAI's latest flagship image generation model, with an official release date of December 16, 2025. It is described as the most capable general text-to-image model currently available, adopting a native multimodal architecture that combines a Transformer backbone with diffusion-based image generation, enabling unified processing of text and image inputs.
Main capabilities
- Generation speed: up to 4x faster than previous versions, complex prompts can be completed within 2 minutes, and simple prompts take only seconds, making it suitable for rapid iteration.
- Precise editing: only the parts specified by the user can be modified while preserving lighting, composition, logos, and facial features, without regenerating the entire image.
- Text rendering: capable of generating clear, readable, and stylized text, suitable for posters, menus, infographics, and marketing materials, with better handling of dense, smaller text than competitors.
- Logo and face preservation: maintains consistency of brand logos and human faces across multiple edits, suitable for marketing campaigns, e-commerce product catalogs, and character design.
- Conversational editing: edit images using natural language instructions, such as "change the lighting to sunset" or "make the jacket blue," without layers, masks, or Photoshop skills.
- Multi-image input: upload up to 16 reference images for editing, style transfer, and composition guidance.
- C2PA provenance: built-in C2PA metadata content authentication to verify AI-generated images.
- API cost: image input and output pricing is 20% lower than GPT Image 1, with quality and low-cost parameters to balance cost and results.
Performance data Official materials state that GPT Image 1.5 improves complex prompt adherence accuracy by 30%, improves text-to-image generation by 147 points compared with the previous generation, and improves image editing performance by 245 points. On the LMArena leaderboard, it scores 1264 for text-to-image and 1409 for image editing, ranking first in both.
