"Said to be"

[Elke]

Hello,

recently, I came across the following sentence "How is GTP-4 said to be". What does it mean? How can I use it? Is it common or not? 

I'm looking forward to the answer.

Bye Elke

Hi Elke,

Thank you for the question.

'it's said to be ...' is the Passive form of 'People/experts say that it is ...', e.g. GTP-4 is said to be more performant than GTP-3.

So, the phrase you've typed seems incomplete.

We need the phrase to continue, e.g. 'How is GTP-4 said to be changing the workplace?'
