Has it changed much since March when this was written? Gemini won, 6-4. And it matches my experiences of just using Gemini instead of ChatGPT because it gives me more useful responses, when I feel like I want an AI answer.
"For this initial test I’ll be comparing the free version of ChatGPT to the free version of Google Gemini, that is GPT-3.5 to Gemini Pro 1.0."
The free version of ChatGPT is 4o now, isn't it? So maybe Gemini has not gotten worse, but the free alternatives are now better? When I compare ChatGPT-4o with Gemini-Advanced (wich is 1.5 Pro, I believe) the latter is just so much worse.
