Bob is the thief is the correct answer.
Why traditional, generative AI fails:
- Logical Reversal Complexity: The model must correctly interpret "one truth, two lies" and reverse implications.
- Contradictory Statements: If Bob is truthful, Charlie must be lying, which contradicts Alice’s statement.
- Common LLM Mistake: GPT-4o (and other models) incorrectly assume Bob is truthful, which leads to a logical inconsistency.
The quantum diffusion LLM model effectively breaks the "reversal course" (Berglund, L., Tong, M., Kaufmann, M., Balesni, M., Stickland, A. C., Korbak, T., and Evans, O. The reversal curse: Llms trained on” a is b” fail to learn” b is a”. arXiv preprint arXiv:2309.12288, 2023.)
