🎨 Customizing Your Illustration Style with OpenAI

This paragraph introduces the concept of training a custom fine-tuned model using OpenAI, focusing on the 'style' model. The video guides viewers on how to create a personalized illustration style that can be used to generate images for various purposes, such as articles or presentations. Key points include the importance of quantity (uploading between 4 to 128 images), consistency (maintaining a common theme across images), and variety (including different subjects like people, animals, and objects). The speaker also discusses a common issue with the model not capturing the intended theme and suggests solutions like uploading more images or adjusting the prompt. The process of training the model and generating examples according to the chosen style is demonstrated.

👥 Developing a Character Model with Diverse Poses

The second paragraph emphasizes the creation of a character model, stressing the need for a variety of poses and angles to help the model understand the character's features from all sides. The character 'Aane' is introduced as an example, showcasing how the model can be used to place the character in different clothing or settings. The process involves selecting the 'character' model type and uploading multiple images of the character to ensure consistency. The paragraph also mentions the option to use existing character artwork or to generate a character from scratch, with additional resources provided for the latter.
