Apple researchers introduced GSM-Symbolic, a new benchmark designed to test the mathematical reasoning capabilities of LLMs. Unlike static datasets, it uses templates to dynamically alter names, numbers, and variables. The results showed that model accuracy plummeted when simple numbers were changed, indicating that high scores on existing benchmarks are due to pattern matching on training data rather than genuine logical reasoning.
