PHYSIX OBSERVATION
MiniMax is rapidly acquiring users through low prices and free strategies, but the memorization controversy exposes the model's weak generalization ability. If evaluation scores rely on memorizing old questions, real-world applications could fail. The industry needs to guard against leaderboard gaming, and users should pay more attention to performance in real scenarios.
