Custom Gems
Learn about Custom Gems in this comprehensive lesson.
Gems are customized versions of Gemini that you can create for specific tasks. (Similar to Custom GPTs in ChatGPT).
- Give your Gem a name (e.g., "Coding Mentor").
- Write a custom system instruction (e.g., "You are an expert Python tutor. Never give me the direct answer, just give me hints").
- Use this Gem anytime you want that specific behavior without re-typing the prompt.
Availability
Custom Gems are currently a premium feature available to Gemini Advanced subscribers.
