A new paper from arXiv questions the effectiveness of "latent tokens" in large language models, particularly within the Chain-of-Continuous-Thought (COCONUT) framework. Researchers Yuyi Zhang and colleagues found that these latent tokens act as uninterpretable placeholders rather than encoding genuine reasoning processes. Their experiments suggest that COCONUT, while appearing stable, primarily exploits dataset artifacts and shortcuts, leading to inflated performance on benchmarks like MMLU and HotpotQA without demonstrating true reasoning capabilities.
