OpenAI has integrated a new image generator directly into ChatGPT, replacing the previous DALL-E 3 version with the powerful multimodal GPT-4o model. The tool shows significant progress in quality and capabilities, helping to create more accurate and functional images. The feature is available to all users, including those on the free tier (with a limit of three images per day).
Technical Features of the GPT-4o Image Generator
OpenAI engineers have completely redesigned the foundation of the generation technology. Instead of the approach used in most existing systems, GPT-4o uses fundamentally new methods.
The model creates images sequentially, from left to right and top to bottom, unlike DALL-E 3, which forms the entire picture simultaneously. This allows for significantly improved accuracy in rendering text and complex elements. GPT-4o can also correctly process up to 15-20 objects simultaneously, preserving all their properties without confusing attributes—a problem that limited previous models to 5-8 elements. Thanks to integration with chat context, the system analyzes the entire previous conversation and user-uploaded images to create more relevant results.
Key Improvements in ChatGPT's Image Generator
Testing GPT-4o revealed four areas where progress is most noticeable. These improvements make the new image generator a practical tool for professional use.
1. Flawless Text Generation on Images
In previous versions, text on images was often illegible or contained errors. GPT-4o completely solves this problem, generating clear, grammatically correct captions that blend organically into the composition.
Creating infographics, posters, restaurant menus, and advertising banners has now become much more efficient. The text is not only readable but also maintains correct stylistic accents, which is critical for marketing materials. Tests show that the model handles even complex multilingual captions, although minor inaccuracies sometimes occur with non-Latin alphabets.
2. Character Consistency Across Image Series
GPT-4o has "visual memory," allowing it to maintain recognizable character features when generating a series of images. This is an important achievement for creating consistent visual stories and social media content.
When creating multiple scenes with one character, the system maintains consistency in their appearance, changing only facial expressions, poses, or clothing according to context. For brands and marketers, this opens up the possibility of developing recognizable brand characters without having to repeatedly describe their appearance in each request. The same principle works for objects and environments, ensuring visual cohesion between images.
3. Enhanced Photo Editing Capabilities
The new model allows users to upload existing images and modify them using text prompts. Users can change the time of day, weather, add or remove objects, transform the style, and much more.
Particularly impressive is the system's ability to maintain the overall atmosphere and composition of the original while making changes. When editing photos, GPT-4o takes into account perspective, lighting, and other parameters to make new elements look natural. This feature saves hours of work in graphic editors for marketers, designers, and content creators who often need to quickly adapt visual materials.
4. Deep Understanding of Visual Context
GPT-4o analyzes the images you upload and takes them into account when creating new content. This allows the system to adapt to your visual style and preferences.
The model can recognize the color palette, compositional solutions, and overall aesthetics of uploaded examples, and then apply these characteristics when creating new images. For brands, this means the ability to maintain visual consistency in marketing materials without writing detailed instructions for each request. It's enough to show the system a few examples of brand style, and it will adhere to the specified parameters.
Limitations of the GPT-4o Image Generator to Be Aware Of
Despite its impressive capabilities, the new image generator has several limitations that are important to consider in your work.
Increased Image Generation Time
Creating a single image takes up to a minute instead of 10-15 seconds with DALL-E 3. This is due to a more complex algorithm that ensures high quality. For large-scale projects, it's recommended to distribute tasks across multiple sessions.
Working with Non-Standard Formats
GPT-4o may experience difficulties with extremely elongated proportions. For best results, use standard aspect ratios: 1:1, 4:3, 16:9, or 3:4. If necessary, create non-standard formats in parts.
Limitations with Complex Structures
The system may inaccurately display many small details or strict structures (complex diagrams, tables). For complex information, it's better to break it down into logical blocks and generate them separately.
Working with Non-Latin Fonts
When using Cyrillic and other non-Latin alphabets, minor errors sometimes occur, especially in complex compositions. It's recommended to carefully check results and possibly make several attempts with different phrasings.
How to Combine Image Generation with Other AI Tools
ChatGPT's new image generator complements other AI services well, creating a comprehensive ecosystem for work.
For example, during concept discussions in meetings recorded and transcribed using mymeet.ai, the team can immediately visualize ideas through ChatGPT. The mymeet.ai service automatically connects to meetings, creates transcripts and AI reports, capturing all key decisions that can then be visualized.
This approach is especially effective in design processes, where concept discussions are immediately transformed into visual prototypes, shortening the path from idea to implementation.
Practical Use Cases for ChatGPT's Image Generator in 2025
The new tool finds applications in various fields. Here's how different specialists can use it in their work.
Applications in Marketing and Advertising
Marketers gain a tool for quickly creating visual content needed in digital communications. With GPT-4o, you can create a series of consistent social media posts with a unified style, quickly visualize advertising campaign concepts for discussion with clients, generate variants for A/B testing, and adapt materials for different audiences without involving designers.
Use in Education and Science
For teachers and scientists, the generator provides access to quality illustrations. Complex scientific concepts become easier to explain with visual materials. Historical events are visualized with high accuracy, making learning more engaging. Personalized educational materials can be adapted for specific tasks, and infographics help present complex data in an understandable format.
Possibilities for Designers and Developers
Designers use the tool as an assistant for prototyping. Application interfaces can be quickly visualized before detailed elaboration. For games, the generator creates concept art for characters and environments, saving weeks of work. Architectural visualization helps present buildings in different conditions, and design systems can be illustrated with specific examples.
Benefits for Small Businesses and Startups
The generator provides the greatest value for companies with limited budgets. Creating logos and brand styles becomes accessible even without special skills. For marketplaces, you can independently generate product images. Advertising materials are created quickly and with professional quality, and updating content for social media no longer requires constant expenditure on designers.
