    -Famous celebrities are featured because AI can more reliably generate images of well-known people due to the abundance of their images available for study.

  • What is the 'mid-journey' and how is it used in creating AI images?

    -Mid-journey is a program that uses the information a computer has learned from studying pictures to create new images based on that information. It can generate images of people, including those who are not famous, by using reference images.

  • What are some telltale signs that an image might be AI-generated?

    -Some signs include inconsistencies in features such as different sized pupils, misshapen or oddly positioned body parts, and objects that appear out of context or with incorrect proportions.

  • How does the AI generate an image of someone who is not famous?

    -The AI can generate an image of a non-famous person by using a reference image and creating images based on that reference, without explicitly asking for the person by name.

  • What is the special command '--CRF' used for in the mid-journey process?

    -The '--CRF' command is a character reference feature that allows the AI to use a specific image as a reference for generating images moving forward.

  • How does the AI handle generating images with multiple elements, such as a person in a specific setting?

    -The AI uses the provided reference image and the description given by the user to generate an image. However, it may not always understand the context or relationships between elements, which can result in humorous or incorrect combinations.

  • What is the limitation of using outside images as a reference compared to using mid-journey's own generated images?

    -Mid-journey is better at using its own generated images as a reference because it has more context and information about those images, making the generated images more accurate.

  • What is the advice given at the end of the video for those who want to learn and improve with this technology?

    -The advice is to engage with the community by asking questions, sharing knowledge, and learning from others to stay up to speed with the technology and improve one's understanding and skills.
