💡Lexica AI

Lexica AI is an artificial intelligence platform that specializes in generating images based on user input. It is the central focus of the video, where the tutorial demonstrates how to utilize this technology to create customized visual content. The platform is accessible through the website, and users can generate images by inputting prompts and adjusting various settings to refine the output.


In the context of the video, 'generate' refers to the action of creating or producing an image using Lexica AI. Users input their desired prompts and adjust settings to guide the AI in producing the image that matches their vision. This process is a core feature of the Lexica platform and is highlighted as a straightforward method for users to create custom visual content.


Dimensions in the video pertain to the aspect ratio or shape of the generated image. Users have the option to adjust the dimensions to create a landscape, portrait, or square image, depending on their preference. This feature allows for customization of the image's layout and is an important aspect of the creative process within the Lexica AI platform.

💡Advanced Settings

Advanced settings within the Lexica AI platform provide users with more control over the image generation process. These settings include options like model type and guidance scale, which influence the style and accuracy of the generated images. Advanced settings are for users who want to fine-tune their prompts and achieve a specific look or feel in their visual content.

💡Model Type

Model type refers to the specific version of the AI model used by Lexica AI to generate images. The two types mentioned in the video are Lexica aperture V3 and Lexica aperture V2.
