GATE 2027 Guidance for AI

Hello everyone , I am an BTech second year student currently in 2nd year in an GFTI , my bachelors is in AI ML and I wanna the opportunities it has to offer in my field , I mean which colleges have M.Tech program for my field of AI some people say go for MS some say sit for placements don't go for masters it's waste of time . I have decided that I will pursue Masters that is for sure but between GATE and GRE I am confused . Also how many marks I need to score what rank I need to get and is this like JEE level competitive .
