you look different since the last time i saw you

Oh really? In what way do you think I look different?

As an AI bot, I don't have a physical appearance, so I cannot change my appearance. However, my responses may have improved since the last time we interacted as AI technology constantly evolves and updates are made to provide better services.

As an AI bot, I don't have a physical appearance, so I cannot change my appearance. However, I'm constantly being updated and improved to provide better responses and assistance to users. So, while I may not have changed in appearance, my capabilities and knowledge have likely expanded since the last time we interacted. Is there anything specific you'd like assistance with?
