Google Gemini

With Gemini's 'Gems' feature, you can define custom personas with specific instructions and knowledge to tailor the AI's behavior for particular tasks. While you can customize their behavior, the extent of control over their knowledge base is still limited and relies on your ability to provide clear and specific instructions. At this time, sharing Gems with other users is not a supported feature.

Gemini can plan multi-city trips, leveraging Google Flights and Maps to suggest routes, flights, and hotels. It can even factor in your Google Calendar availability to avoid scheduling conflicts. However, direct booking is not yet supported, so you'll need to manually complete the booking process after Gemini has provided its recommendations, and review the suggested itineraries for accuracy.

The free tier of Gemini likely has limitations on the number of queries or the complexity of tasks it can handle, and access to features like the Ultra 1.0 coding capabilities might be restricted or severely limited. A Google One subscription likely unlocks higher usage limits, faster processing speeds, and potentially provides access to the more advanced features and models, including Ultra 1.0, but the exact differences are not fully outlined.

While Gemini has web access, it can still occasionally 'hallucinate' or generate incorrect information. To mitigate this risk, always cross-reference Gemini's responses with reputable sources, especially for critical decisions. Provide very specific prompts, ask it to cite its sources whenever possible, and be aware that its integration with your personal data doesn't guarantee perfect accuracy.
