Mastering Consistent Characters in Leonardo AI: How to Make AI Influencers (Step-by-Step Tutorial)

The video begins with the host, B from blogwithb.comom, introducing the topic of creating consistent characters using Leonardo AI. B emphasizes the importance of having a consistent theme across a portfolio, especially for those interested in AI influencers. The host shares the potential revenue from AI influencers and encourages viewers to adapt to the changing world of technology. The tutorial promises to cover two methods of character design, provide tips for refining designs, and help viewers stand out in the field of AI-generated content. B also encourages viewers to subscribe for more resources and AI tech trends.

The host points out the helpful documentation available within the Leonardo AI platform, which can be accessed through an icon on the dashboard for support and tutorials. The video will cover the steps listed in the help documentation, providing clarity on creating consistent characters. B also mentions a previous tutorial for beginners on mastering Leonardo AI, which offers an in-depth overview of the platform. The host then introduces two methods for creating consistent characters: using prompts with a fixed image seed and creating a trained model with inputted data or images.

The first method demonstrated involves using the image generator to create a character with a descriptive prompt, then using a 'seed' to guide the AI in generating similar images. The seed is a numerical series that the AI uses as a reference for image generation. B explains the process of creating an AI influencer character and emphasizes the simplicity of using Leonardo for this task. The host also discusses the configurations for the image generation, including the number of images generated, the use of different pipelines, and the importance of image dimensions for training models. The video shows how to copy the seed and use it with a new prompt to generate images that maintain the character's features across different settings.

After creating the initial character image, the host shows how to modify the prompt to place the character in different settings, such as a hotel lobby or a fancy restaurant, while maintaining consistency through the use of the fixed seed. B demonstrates how the AI generates images that are consistent with the original character's features, allowing for creative freedom in changing the character's actions and environment. The host also shows how to adjust the prompt to change the character's mood, further illustrating the flexibility of the AI in generating human-like portraits.

The second method involves training a custom Leonardo model using multiple images of the character. The host explains the process of creating a data set with similar images and uploading them to the Leonardo platform. The video covers the steps for naming the data set, uploading images, and configuring the model's training settings, including resolution, base model, category, and instance prompt. B also discusses the importance of using a consistent image size and the recommended number of images for training the model. The host demonstrates how to train the model and monitor its progress, as well as how to use the trained model in the image generator.

After training the custom model, the host shows how to use it to generate new images with a consistent character. B discusses the differences in quality due to the base model used for training and the original image generation. The host then provides tips for fine-tuning the model's results, such as changing the model category and experimenting with different settings. The video also demonstrates how to use a fixed seed with the custom model to maintain consistency across images. B encourages viewers to experiment with different models and settings to achieve the desired results.

The host concludes the video by summarizing the methods for creating consistent characters with Leonardo AI and encouraging viewers to explore Leonardo's help documentation for more tips and guidance. B offers assistance for any questions or suggestions and appreciates the support from the viewers. The host also promotes their step-by-step tutorials for starting a blog and thanks the viewers for watching the video.
