Introduction
On December 16, 2025, OpenAI launched GPT Image 1.5, the model that changed the rules of digital image production and editing. This was not a routine update, but a qualitative leap that made image generation four times faster, more accurate in following instructions, and better at preserving details during modifications.
GPT Image 1.5 comes integrated as a native part of the GPT family as a multimodal model, meaning deeper understanding of both text and images together. The result: high‑quality images that follow instructions with unprecedented precision, and surgical edits that change only the requested elements.
In this article we will review the precise technical specifications, comparative performance, practical applications, and access methods based only on official OpenAI data.
What is GPT Image 1.5?
GPT Image 1.5 is the new flagship model in OpenAI’s GPT Image family. Officially released on December 16, 2025, it became immediately available in ChatGPT for all users, and via API under the name gpt-image-1.5.
The model is built as a native multimodal language model, unlike traditional separate diffusion models. It focuses on high productivity: generating professional‑quality images with strong instruction adherence, and natural editing that preserves composition, lighting, faces, and logos.
GPT Image 1.5 gradually replaces reliance on DALL·E 3 (which will be discontinued on May 12, 2026), and is the most powerful in the GPT Image series, which includes GPT Image 1 and GPT Image 1‑mini.
Key Technical Specifications of GPT Image 1.5
- Inputs: text + images (up to 5–10 reference images).
- Outputs: images (PNG, JPEG, WebP).
- Supported resolutions: 1024×1024, 1024×1536, 1536×1024 (with auto option).
- Quality settings: low, medium, high, auto.
- Speed: 4× faster than GPT Image 1.
- Cost: 20% lower for input and output images.
- Key capabilities: text‑to‑image generation, natural‑language instruction editing, preservation of faces, logos, lighting, and composition, rendering dense text with high accuracy, transparent backgrounds, and partial streaming during generation.
The model supports input_fidelity: high to preserve the highest resolution of input images, and allows multi‑cycle modifications without loss of consistency.
Performance and Comparisons
GPT Image 1.5 is classified as OpenAI’s best general‑purpose image‑generation model to date, with clear superiority in instruction adherence, text accuracy, and precise editing. According to OpenAI, it achieves more reliable and natural results, especially in preserving details across repeated edits.
Here is a comparison table within the GPT Image family based on OpenAI’s official documentation:
| Model | Relative Speed | Relative Cost | Instruction Adherence | Detail Preservation During Editing |
|---|---|---|---|---|
| GPT Image 1.5 | 4× faster | 20% lower | Highest | Excellent (surgical) |
| GPT Image 1 | Slower | Higher | Good | Good |
| GPT Image 1‑mini | Faster | Lowest | Good | Limited |
| DALL·E 3 (deprecated) | Medium | – | Medium | Limited |
GPT Image 1.5 stands out in dense‑text accuracy (such as newspapers or posters), preservation of faces and logos during editing, and realistic logic in complex contexts.
Real‑World Practical Applications of GPT Image 1.5
-
Product‑image modifications: Upload a single product image and request “Change the background to a sunset beach while adding the company logo in hex #007BFF blue without altering the product itself”. The model preserves lighting, composition, and fine details.
-
App‑interface design: “Create a mobile‑app interface for Arabic‑language shopping with clear buttons and dense text.” Supports complex text and layouts with high accuracy.
-
Sequential edits: Upload a portrait and ask “Change the clothes to a formal suit while keeping the face and lighting” then “Add a modern office background.” Maintains consistency across cycles without full regeneration.
-
Marketing‑content creation: “Turn this image into a complete ad with clear Arabic text and a professional background.” Produces results ready for commercial use at high speed.
-
Product‑catalog creation: From a single source image, generates variants, angles, and different scenes while preserving visual identity.
