Can anyone explain to me why this is brilliant?

I played against Pincer, the hardest bot of this month and when I game reviewed it, he played a brilliant move but I don't understand why it's brilliant. Please explain: https://www.chess.com/analysis/game/computer/124362751?tab=review&move=25

No idea... But activated a sequence of events after thats so

Chess.com is generous with the brilliant label.
A true brilliant move satisfies 4 criteria:

1. It is a winning move: losing or drawing moves are not brilliant.
2. It is unique: when two moves win, then none is brilliant.
3. It involves a sacrifice, as sacrifices are aesthetically pleasing.
4. It is a quiet move: no check (+) or capture (x), as those are too obvious to be brilliant.

Here is an example:
30 Ba3 satisfies all 4 criteria and thus is a true brilliant move.

No.1 and No.4 are not true:

Because it is sacking a rook and it doesn't loose

I feel bad when a bot plays a brilliant move against a human

Well the first criteria says it shouldn't be a losing or drawing move. These are drawing moves. The fourth criteria says it shouldn't be check or capture. These are checks

I believe someone got a brilliant move that is loosing before

To be awarded the "brilliant" designation, a move must satisfy two criteria. 1 It must be the best move according to the computer evaluation, and 2 it must be hard to find. Whether or not a move is hard to find or not is inherently subjective, and it is hard for a computer to judge what a human would consider hard to find. The algorithm probably thinks that a human would be tempted to attempt to save the Rook with 13 ... Rh7, which leads to a powerful attack for White after 14 Rxe6. Nf8 is best because it defends that pawn.

Could be worse, but not losing. 
The brilliant is basically sacrifice and best move, and hard to find too. Like nowadays I sac my queen all the time but they don't get brillaint.
For why Nf8 is brilliant, its because its the best move.

I promise you I saw a brilliant move that was loosing it was the best move just loosing i just wish I could find the game
