English(EN) Quantization Inflates Reasoning: Token Inflation as a Hidden Cost of Low-Bit Reasoning Models

研究发现：低比特量化会膨胀大型语言模型中的推理Token

作者 PulseAugur 编辑部 · [2 个来源] ·

一篇新发表在arXiv上的研究论文探讨了对大型语言模型进行低比特量化所带来的隐藏成本，尤其是在推理任务方面。研究表明，虽然量化可以保持准确性并降低每个Token的延迟，但它通常会导致推理生成的Token数量增加，从而抵消了预期的加速效果。这种被称为“Token膨胀”的现象会导致更长的思维链、更多的中间步骤和语义重复的增加，最终影响实际的服务成本。研究还评估了缓解策略，并提出量化感知训练在降低准确性下降和Token膨胀方面显示出潜力。 AI

影响 量化感知训练可能对于推理型大型语言模型的有效部署至关重要。

    Quantization Inflates Reasoning: Token Inflation as a Hidden Cost of Low-Bit Reasoning Models

    Quantization is widely used to reduce the inference cost of large language models, but its effect on reasoning models is not fully captured by final-answer accuracy or per-token latency. We show that low-bit post-training quantization can introduce a hidden test-time compute cost…
