Farthest monster black hole found
Astronomers have discovered the most distant "supermassive" black hole known to science.
The matter-munching sinkhole is a whopping 13 billion light-years away, so far that we see it as it was a mere 690 million years after the Big Bang. But at about 800 million times the mass of our Sun, it managed to grow to a surprisingly large size such a short time after the origin of the Universe. The find is described in the journal Nature [DOI: 10.1038/nature25180] [DX].
This relic from the early Universe is busily devouring material at the centre of a galaxy - marking it out as a so-called quasar.
Also at Sky & Telescope.

13 billion light years away, we are seeing it at 690 million years after the big bang and it was 800 million times the mass of our sun at that time. How large is it now??

you are asking about events outside of our lightcone.
according to my understanding, that is a meaningless question, because the object you are interested in could have interacted with things that we cannot observe at any moment in their history.
furthermore, if something is outside our lightcone, it does not exist (as far as physics is concerned).
