While ChatGPT automatically picks the best model for the query, Google's Gemini models require users to manually pick the model they believe is best for the job. But, with so many models that cater to a wide array of tasks, this can leave users scratching their heads as they pick one.

From sharing screens and real-time inqueries to complex data analysis, each Gemini iteration brings unique capabilities and distinct strengths to the table. Additionally, features like Deep Research and Personalization expand the horizons of what these models can achieve.

Google currently offers many of their best features for free and is currently offeing college students Gemini Advanced for free so it's a good time to understand what these models are capable of and how to best put them to work.

Additionally, features like Deep Research and Personalization expand the horizons of what these models can achieve. After testing every model, I've put together a guide that delves into the strengths of each one, where to find them, as well as practical prompts to help users harness their full potential.

Why These Prompts Work: These prompts work because they’re rooted in context and customization. By pulling from your personal history and preferences, the model can generate responses that feel intuitive and tailored—turning general AI into a highly personalized assistant.

Final thoughts

This Gemini guide is just a starting point to better understand the models as you explore them. The prompts I've included can be tweaked to ones that better pertain to your own queries, but they are a good starting point to getting to know the models.

There's a lot of models here, and all are worth exploring. There's no need to stick to one, especially since Google has offered many for free. Now that you have a general understand of the distinct functionalities of each one, you can benefit from the capabilities of each. But I'll be honest; even I don't use all of them all the time.

As Google continues to expand their capabilities and offerings, keep it here to say informed about these tools. Which one do you use most and why? What's your favorite and least preferred model? Let me know in the comments!
