Claude 3.7 Sonnet
The model hasn't been super schizo with me, and has been pretty stable; although you sometimes have to locate where the real Twilight is, and not that winged thing that sometimes resides in the Golden Oaks Library.
Luna even mentioned and critiqued Starswirl the Bearded's works on explorations of other worlds when it was brought up that my character was found to be bound between two worlds. (Mirrors from the comics) It does well with the world knowledge of Equestria; at least, from what I've experienced.
