I’ve just beaten the Chessup 2 bot supposedly rated at 1600 but I’ve played better opponents rated 500. I can’t believe the blunders that the bots make and the moves they miss.
The bots just don’t seem anywhere near as good as there rated ELO level.

Hi ChessBryUK - I’m nowhere near that level. I seem to have found my level to be about 1100 against the bots. I play the 3 bots on chess_com and the internal one and they all seem to be roughly equally challenging but with different ‘personalities’ at the 1100 level. Not sure if that’s helpful info, just thought i’d throw it out there.

I find the bots on Lichess a lot harder, maybe I’m just improving 
It’s impossible to lose against the Chessup board bots though, just offer a draw and they always accept!
For me, the bot was easy to beat up to the 1400 level (non-Stockfish). However, the jump to 1500 (the first Stockfish level) is significant and not smooth at all. In comparison, the 1500 Stockfish bot plays at a similar level to a 1900 bot on Chess.com, and even Lichess’s 1700 Maya bot doesn’t play as well
If I take my time then I can beat them, so far at 1600 or less, but if I’m time limited then I don’t stand a chance! I use the bots more for analysis and building concentration, without the pressure of time.
Looks like they have updated the strength of the ChessUp 2 bots since your post? I checked level 12 “1500” and I think it’s playing around the 1900 level. I’m checking level 13 “1600” now.
