Testing Google Gemini 1.5 Pro

How does it compare to its little brother, Gemini Flash

I recently wrote an article where I tested Gemini 1.5 Flash, one of Google newest LLM models that is available in Preview. In that article, I was comparing it to OpenAi’s GPT-4o as they were both released around the same time. You can find that article below,

Anyhow, one reader thought that comparison was a bit unfair and that I should really be pitting Gemini 1.5 Pro against OpenAI’s new model.

So I’ll be testing Google’s Gemini 1.5 Pro model today and as usual, I will be asking the model my 7 logic, reasoning, coding and maths questions plus a bonus picture question to test its vision capabilities.

Like Gemini Flash, Gemini pro is available to preview. Head over to Google’s AI studio. You can find it here.

You should land on a page that looks like this,
