GPT Image 1.5
GPT Image 1.5 is an image generation model developed by OpenAI and released in December 2025. It serves as the engine behind the ChatGPT Images experience and is also available to developers via the API using the model ID gpt-image-1.5. The model supports both text-to-image generation and image editing, with output resolutions up to 1536×1024 and 1024×1536 pixels. It ranks first in the Image Edit category on the Chatbot Arena leaderboard. The model is designed to follow nuanced editing instructions, changing only the specified elements of an image while preserving lighting, composition, and overall context. It maintains consistent facial likeness across inputs, outputs, and sequential edits, making it well-suited for photo retouching, virtual try-ons, stylistic transformations, and multi-image compositing. Text rendering accuracy is notably improved compared to its predecessor, and generation speed is up to 4x faster. It is accessible to all ChatGPT users as well as developers building applications in e-commerce, marketing, and creative tooling.

Capabilities
What GPT Image 1.5 supports
Precise Image Editing
Adds, removes, blends, or transposes elements in existing photos while preserving lighting and composition. Follows nuanced instructions to change only the specified parts of an image.
Face & Character Preservation
Maintains consistent facial likeness across inputs, outputs, and sequential edits. Useful for portrait retouching, virtual try-ons, and character consistency across a chain of edits.
Inpainting
Modifies specific regions of an image without affecting surrounding areas. Allows targeted edits such as replacing backgrounds or altering individual objects.
Improved Text Rendering
Generates images containing readable text with higher accuracy than the predecessor model. Suitable for creating mockups, signage, and branded visuals.
Multi-Image Compositing
Blends subjects from multiple source images into a single coherent scene. Accepts image URL arrays as input to support multi-source compositing workflows.
Fast Generation Speed
Produces images up to 4x faster than its predecessor model. Speed improvements apply to both generation and editing tasks.
API Access
Available via the OpenAI API using the model ID gpt-image-1.5. Suitable for developers integrating image generation into e-commerce, marketing, and creative applications.

The strongest match in this snapshot has 1157 upvotes and 240 comments.
The image generation war just heated up again. OpenAI has officially dropped **GPT-Image-1.5** and it has already dethroned Google on the leaderboards.
**The Benchmarks (LMArena):**
**Rank:** #1 Overall in Text-to-Image With **Score** 1277 (Beating Gemini 3 Pro Image / Nano Banana Pro at 1235).
**Key Upgrades:**
**Speed:** 4x Faster than the previous model (DALL-E 3 / GPT-Image-1).
**Editing:** It supports precise "add, subtract, combine" editing instructions.
**Consistency:** Keeps character appearance and lighting consistent across edits (a major pain point in DALL-E 3).
**Availability:** ChatGPT: Rolling out today to all users via a new "Images" tab in the sidebar.
**API:** Available immediately as gpt-image-1.5.
**Google held the crown with "Nano Banana Pro" for about a month. With OpenAI claiming "4x speed" and better instruction following, is this the DALL-E 3 successor we were waiting for?**

Many people did not like my "realistic" results, so i tried again. Still not perfect, but better than before.
The first 3 images of each set are GPT image 1.5, the rest is Nano Banana Pro.
I think Nano Banana Pro won this round.
Introducing ChatGPT Images, powered by our flagship new image generation model.
* Stronger instruction following
* Precise editing
* Detail preservation
* 4x faster than before
Rolling out today in ChatGPT for all users, and in the API as GPT-Image-1.5.
[https://openai.com/index/new-chatgpt-images-is-here/](https://openai.com/index/new-chatgpt-images-is-here/)
Have seen a lot of examples from both models and I can say pretty surely that nana banana pro is much better than gpt-image-1.5.
