Train Firefly Custom Models

On the Adobe Firefly homepage, select Custom models.

Browse popular use cases you can train models for. Select one of the use cases to train your own model for that use case. These include:

• Lifestyle photography
• Photoshoot of a person
• Still life photography
• Illustrated character
• Iconography
• Illustrations
• Isometric and 3D graphics
• New Brand expression illustrations
• New concepts

If you don’t see the right use case listed, select Start with your own images. 

When you create your own custom model, you can select to train it on a subject or a style.

Drag and drop 10-30 images to train the model, referencing best practices for training custom models. 

Make sure the images you add meet the following criteria:

• Aspect Ratio: Maximum of 16:9
• File Format: JPG or PNG
• Resolution: Minimum of 1000 pixels

You will see errors if the images include issues such as low resolution that should be fixed prior to training.

Select Generate Captions & Tags to generate these based on the images you provided.

Based on what you upload, we will automatically generate the following information for you to review and edit:

• Model title: The title you will see when selecting your model.
• Model description: A description of what the model generates.
• Sample prompt: This gives individuals who use your model a starting point to decide what prompts to use with your model.
• Model Tags: Permanent attributes of the subject or style you're training a model on, such as brown hair for a brunette character. Do not include changeable attributes in Tags, like what object a character is holding.
• Captions: Notable parts of each training image are described using language similar to what you will prompt with, such as “young woman wearing a green sundress and holding a seashell at the beach, photorealistic.” Models trained on a subject (i.e., character, person, or still life object) should include the model Concept in each caption.  

Select Train. This may take a few hours. You will see a progress indicator that estimates the amount of training you have completed.

You may close this tab and open your model again from Model Inventory.

Models will typically show the following statuses:
