Gemini Advanced, Business, and Enterprise subscribers can create a new Gem or Custom Gemini model by logging into their Gemini page and beginning the process by locating the Gem Manager button.
Once a user has created a new gem, they must write instructions for it to follow, wrote Dave Citron, senior director of product management at Gemini Experiences, in a blog post.
Users are asked to detail goals, desired behaviors and preferred format to help Gem personalize Gemini's responses, much like the practice of writing good messages, Citron explained, adding that the main areas to consider are person, task, context and format.
