What we have here is a 'KQBN vs kqbppp' five-move chess puzzle or problem (whichever you wish to call it) composed by the prototype computer program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated. This position contains a total of 10 pieces. The largest endgame tablebase in existence today is for 7 pieces (containing over 500 trillion positions anyway) which means the problem could not have been taken from it regardless.

If you notice any version of Chesthetica 'skipped' from one problem to the next, that simply means additional (minor) changes were made to the program before it was set to run again. Material is even. If this one is too easy or too difficult for you, try out some of the others. Feel free to copy the position into a chess engine and discover even more variations of the solution.
