As we all know, creating images requires high design skills or expensive software. Not anymore. ChatGPT 4o now lets anyone generate images through simple conversation—just type what you want, and the AI does the rest. No learning curves, no complex interfaces, just results. To give you a deeper insight into this innovative AI tool, we'll guide you through how to use GPT-4o's image generator step by step. Quit wondering and step closer with use now!
What is ChatGPT 4o and its image generation capability
ChatGPT 4o is OpenAI's latest "omni" multimodal AI model that can process text, images, and audio all in one system. On March 25, 2025, OpenAI added native image generation directly to GPT-4o, letting users create images right within their chat conversations. Unlike previous setups where ChatGPT had to use DALL-E as a separate tool, GPT-4o creates images itself. This integration means the AI understands your conversation context better when making images. It's particularly good at accurately rendering text in images and lets you modify images through natural back-and-forth conversation.
How to use GPT 4o image generator
Using ChatGPT 4o to create images is surprisingly straightforward. You can either generate completely new images from text descriptions or modify existing images through conversation. Let's explore both methods so you can start creating right away.
Method 1: Generate images from text prompts
This is the simplest way to create images with ChatGPT 4o. You just describe what you want to see, and the AI brings it to life. The advantage here is simplicity—no need to learn complex tools or technical terms. Just explain what you're imagining in everyday language, and ChatGPT 4o handles the technical work of transforming your ideas into visual content.
- STEP 1
- Access ChatGPT and select OpenAI GPT 4o model
Visit ChatGPT's official website and sign in—if you don't already have an account, you'll have to create one before you'll be granted access. Once you are signed in, you'll be taken to ChatGPT 4o's homepage. Paid users can change the model directly from the homepage, but as a free user, you'll automatically be locked to ChatGPT 4o and can't switch between models.
- STEP 2
- Write a descriptive prompt
Now, click on the empty box and then write a detailed prompt of the image you want to create. For the best results, mention the style, subject, environment, colors, perspective, and any specific details you want in the image.
For example, you can write: An anime-style illustration of a young warrior girl with vibrant blue hair, holding a glowing sword, dressed in traditional Japanese attire, standing in a forest under moonlight.
- STEP 3
- Review and save the generated image
Once you are done writing your prompt, hit the Enter key, and its AI will begin generating your image. After a few seconds, you'll be presented with an AI-generated image. If you'd like to customize the image, you simply write a follow-up prompt instructing the AI on the changes you wish to make. For example, you could say: make her hold a shield instead.
After editing your image and you are happy with the final result, save it on your computer (PC) by clicking the download icon at the top right corner of your generated image.
Method 2: Interactive image modification through conversation
This method takes image creation to the next level by letting you upload an existing image and then transform it through simple instructions. What makes this approach powerful is its ability to understand your starting point and apply specific changes based on your directions. It's perfect for situations when you have a base image but want to explore creative variations or improvements.
- STEP 1
- Start with a generated image
On ChatGPT's homepage, click on the plus button to upload a file. Search for the image you want to modify, then click on it upload (alternatively, you can just drag and drop).
- STEP 2
- Request specific modifications via text
After successfully uploading your image, write a detailed prompt to tell the AI about the changes you'd love to make. For example, you can upload a portrait of yourself and write a prompt like: Turn my image into a Studio Ghibli style image.
- STEP 3
- Review and save the generated image
Once you are done writing your prompt, hit the Enter key and ChatGPT will start modifying your image based on your prompt. After a few seconds, it'll present you with a modified image. Remember, if you are not happy with the results, you can reprompt by adding a follow-up prompt stating the corrections to make. And, if you are happy with the results, download it by clicking the save icon to save the image on your device.
ChatGPT 4o image generation: Is it really worth the hype
Now, you know you can now use ChatGPT 4o for generating and modifying images, all for free. With all the buzz going on recently since its release, you might be wondering if it's the right choice for you or not. That's why we'll now take a look at its pros and cons to help you decide:
- Integrated with conversational AI: The biggest advantage is how naturally image creation fits into regular chat. You don't need to switch apps or learn a new interface—just describe what you want in the same conversation where you're already working. This makes the creative process feel intuitive and approachable.
- Strong understanding of complex prompts: GPT-4o genuinely understands nuanced descriptions and context from your conversation. If you've been discussing a specific topic, it uses that background to create more relevant images. It's particularly good at handling detailed requests with multiple elements.
- Seamless refinement process: The ability to modify images through simple follow-up instructions makes iteration painless. You can ask for specific changes like "make the sky more orange" or "add a sailboat on the left," and the AI applies just those adjustments without starting over completely.
- Autoregressive generation approach: Unlike other AI image tools that build the entire image at once, GPT-4o creates images sequentially (left to right). This difference helps it render text more accurately within pictures and maintain better coherence across complex scenes.
- Limited availability (not fully available to free users): While paid users enjoy full access, free accounts face significant limitations. The rollout to free users has been delayed due to high demand, meaning many can't use this feature yet. Even when access expands, free users will likely face daily image generation limits.
- Potential wait times for image generation: The image generation process can take up to a minute for complex or detailed requests. This might not seem long, but it can interrupt your creative flow, especially when making multiple iterations or adjustments to reach your desired result.
- Less specialized than dedicated image tools: ChatGPT 4o is a jack-of-all-trades AI that generates images, not a specialized image creation tool. This means it lacks dedicated features for advanced editing, precise control over artistic styles, or specialized image manipulation that purpose-built AI image generators offer.
While ChatGPT 4o's image generation is impressive and convenient for casual users already in the ChatGPT ecosystem, serious creators might find it lacks the depth and specialized features needed for professional-grade work. If you're looking for an accessible tool with more control, faster generation, and advanced AI customization features, we also have you covered. In the following parts, we will introduce Dreamina as an accessible, complete, and surprising alternative to supplement your needs. Scroll down and find more!
