Q & A

  • What is the main purpose of the negative prompt generator for Leonardo AI?

    -The main purpose of the negative prompt generator is to help users create high-quality AI images without common issues such as deformities, blurry backgrounds, or asymmetrical figures.

  • How does the double generator feature work in the prompt?

    -The double generator feature allows users to first specify the style and type of image they want, and then offers to provide a series of negative keywords to use with Leonardo AI, ensuring the final image is free from unwanted elements.

  • What are the steps to use the negative prompt generator?

    -First, tell the generator the style of prompt you want, such as realistic portrait or scenery. Then, describe the type of image. The generator will ask if you want negative keywords, and if you agree, it will provide a complete prompt with negative keywords tailored to your request.

  • Why is it important to use the slash character before the command in chat GPT?

    -Using the slash character before the command in chat GPT ensures that the system understands it's a command and not just a regular text input. This helps the system to process the request correctly and avoid asking for additional information.

  • How does the character limit of Leonardo AI's prompt affect the generator?

    -The character limit of a thousand characters per prompt in Leonardo AI means that sometimes the generated prompts from chat GPT can be too long. The generator is set to not exceed this limit, and users are provided with an option to simplify the prompt if necessary.

  • What are the benefits of trying different fine-tuned models with the prompt?

    -Using different fine-tuned models with the prompt can result in a variety of image styles and qualities. Each model may interpret the prompt slightly differently, providing unique and diverse outcomes that can be more appealing or suitable for different purposes.

  • How does the negative prompt generator handle different types of images?

    -The negative prompt generator provides a set of negative keywords specific to the type of image or command given. For example, if a user requests a 'person' or a 'scenery', the negative keywords provided will be different and tailored to avoid common issues for that specific type of image.

  • What is the significance of using the 'write the prompt out in a simpler format' option?

    -This option is used when the generated prompt is too long and exceeds the character limit for Leonardo AI. It helps to condense the prompt into a shorter version while still maintaining its effectiveness, ensuring compatibility with Leonardo AI's character limit.

  • How does the user know when a prompt is too long for Leonardo AI?

    -The user can utilize the 'write the prompt out in a simpler format' option if they notice that the generated prompt exceeds the 1000 character limit. The system provides feedback, and the user can then request a simplified version of the prompt.

  • What is the role of the 'Alchemy presets' in creating different looks for the images?

    -Alchemy presets in Leonardo AI offer additional customization options that can change the look and feel of the generated images. By using different presets, users can achieve a variety of visual effects and styles that can enhance the final output.

  • How can users ensure they get the best results from the negative prompt generator?

    -Users should follow the step-by-step instructions provided in the script, use the slash character before commands, choose the correct fine-tuned model, and utilize the negative keywords provided by the generator. They should also experiment with different prompts and Alchemy presets to find the best combination for their desired image.
