Simplicity Wins: How Removing Filters Achieved 99.1% on the LOCOMO Benchmark

Muninn achieved 99.1% on the LOCOMO benchmark—outperforming competitors by significant margins—through an unexpected approach: removing predicate filtering entirely. This 12-point accuracy leap came not from better algorithms or models, but from simplifying the architecture to search all facts first and filter after. The breakthrough highlights a critical lesson for AI system design: optimization through subtraction often beats engineering more sophisticated solutions.
