Where is Stockfish 9?

Please, I want to see some Stockfish 9 vs Leela...
why you don't activate Stockfish 9? it's a shame!
Leela can challenge the Stockfish AI at any time. This is running on the latest version of Stockfish as far as I know.
But she does not challenge him at all, she only challenges Stockfish 8, does she wrinkle against Stockfish 9?
The Stockfish "levels" available on Lichess are not to be confused with the versions of Stockfish. Lichess runs Stockfish 9, and has the ability to run Stockfish 9 at eight different difficulty settings, which you see as "level 1" through to "level 8".
There is a Stockfish bot playing on lichess, ofc I don t know why it should play against Leela when she cannot even beat SF level 8. At this point in time Sf is in a different league than Leela.
I guess in that video, they are running Stockfish 9 on their own hardware and relaying the moves through the Lichess Bot API ("CruelBot" in the video), and since they are using their own hardware, they can devote more CPU time to Stockfish -- more than Lichess probably does even when you select "level 8".

But when we currently see Leela online, she is spotlighted differently, as Bot Leelachess, and on this video, Stockfish 9 is spotlighted as Bot Cruelbot.

Does this mean that Leelachess is currently running on a independent hardware?

Moreover, on this video, Stockfish 8-64 is fighting Stockfish 9-64 and the individual did not select any difficulty stage on both sides.

I believe the LeelaChess bot on Lichess is hosted by lczero.org, and they are using their own hardware, yes.

The difficulty settings are something that Lichess has only. I am not sure how it works exactly, but you could think of it as this: "level 1" gives 0.5 seconds of thinking time to Stockfish, "level 2" gives 1.0 seconds, and so on, until "level 8" gives 5.0 seconds of thinking time. So the higher levels will be harder since Stockfish thinks for longer.

But for every level, Stockfish is still running its latest version (which is version 9, not to be confused with the "levels" here). It's simply configured to think for different times, and thus allow for different difficulty settings. I've maybe complicated the explanation, but that is how it works.

And in the video you've posted, they're playing Stockfish version 8 against Stockfish version 9 at full strength on their own hardware. You wouldn't be able to know what Lichess "level" that their SF v9 is running at, without first knowing the kind of CPU they have and so on.
