I'm using gpt 5.5 xhigh while designing a table schema and it feels dumber than 5.4. but not a strong feeling

it's formatting of output is different as well. It's not wrong, but different, feels more terse than 5.4

maybe it's better at instruction following, and it's picking up on my previous use of plain-language skill
