🚀 How to create your first AI image (step-by-step)
If you've never generated an image with artificial intelligence before, here's a quick guide to get started in minutes. We'll use ChatGPT as an example as it is the simplest option:
Create a free account on ChatGPT
Go on chatgpt.com and sign up with your email address or Google account. It's completely free and only takes a minute.
Write your prompt (image description)
In the chat, describe the image you want. For example: “A ginger cat reading a book in a cosy library, digital illustration style”. The more detailed your prompt, the better the result will be.
Awaiting generation
ChatGPT will process your request and generate the image in a few seconds. You can see the progress in real time.
Refine and edit
If the image isn't exactly what you wanted, you can ask for changes: “Make it more colourful”, “Change the background to blue”, “Add a hat to the cat”. This conversational iteration is ChatGPT's great advantage.
