Train AI models for image generation

Training an AI model can be defined in many ways, but it typically involves teaching the model to perform specific tasks by providing data for it to learn from. With our Model Trainer, "training" means feeding the base model with additional images and creating a unique "instance prompt" token that integrates seamlessly into the powerful FLUX.1 [dev] base model. This process, called DreamBooth, uses a small set of images you upload to personalize the AI’s output. Essentially, you're building your own custom AI image generator!

Whether you're developing a consistent Character or designing a custom Style, this training process lets you tailor the AI to meet your specific needs or preferences, moving beyond the limitations of generic, pre-trained models. Once your model is trained, you can use it directly in our AI Generator to create high-quality, customized images. You don’t need to add the token to the prompt, it’s handled automatically when you enable your Style or Character.

Creating a custom AI model for image generation with getimg.ai’s Model Trainer is a simple and intuitive process. It only takes a few clicks to complete; you don’t need to worry about having to set any complicated training parameters or choosing the right base model for your use case.

The whole thing can be summed up in three easy steps: name your model (and select the gender if you’re training a Character), upload training images and click a button to start the training process. That’s it! Now you just need to wait for the training to finish.

The training time for your custom AI image generator depends on the number of images you upload. The more images you provide, the longer the training process will take. However, we’ve optimized the process to ensure it’s quick and efficient. Once your images are uploaded, the tool gives you an estimated training time so you can plan accordingly.

Even with multiple images, the process is designed to be fast, and you won’t be kept waiting for hours on end. After the training is done, your model will be ready to use, and you can start generating images in the Image Generator immediately. With this streamlined process, you can spend more time creating and less time waiting.

You can only train a model on images you have full legal rights to use for this purpose. Always ensure that your images comply with our terms and conditions—harmful or offensive content is strictly forbidden, and you have to obtain the appropriate permissions if you’re using photos of real people.

Remember, the quality of your training images directly influences the performance of your AI model. For Character models, try to include a variety of photos with different angles, expressions, and lighting. This helps the model understand the full range of your Character’s appearance. For Style models, include different types of scenes, objects, or people that reflect the aesthetic you're aiming for.

FLUX.1-based custom AI image generation models are powerful creative tools that solve real workflow challenges for artists, creators, and professionals. Take graphic novelists and game designers: instead of spending weeks hand-drawing character variations or concept art, they can now train an AI model on their unique Styles and Characters to rapidly explore visual ideas.

For content creators, these models offer unprecedented personal creative flexibility. An indie musician might design consistent merchandise graphics that perfectly capture their aesthetic, without expensive design contracts. Social media creators can experiment with unique visual styles, generating profile images or post graphics that reflect their personal brand more precisely than traditional stock imagery or costly photoshoots.

On a personal level, these models are just plain fun. Imagine generating professional-quality headshots of yourself for LinkedIn that capture different moods and styles. You could also design unique profile pictures for dating apps, generate consistent personal branding images, or even create a visual archive of how you might look in different artistic styles—from vintage photography to anime-inspired illustrations.
