To compare all three (Deepseek, Claude and ChatGPT) I put forward same question to free version of these AI chat bots. The question is, whats the result of Arsenal last game?

DeepSeek gave a simple 2 liner answer that better go and check online to get real time information.

Claude said since cut off date for my knowledge is from October 2024, I can't answer this. But he gave some recommendation where I should go and check about Arsenal last game result.

ChatGPT was one who gave correct answer to this along with web links for more information   

I will do more such test to figure out which is better in performance because one question is not enough to decide which AI chat bot is best.
