研究发现AI“思考模型”使用4个token触发推理

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-23 10:40

研究人员调查了AI中“思考模型”的内部工作原理，特别是关注像Qwen3-4B这样的模型如何处理推理任务。他们发现，“思考”能力并非一个独立的推理引擎，而是通过在提示中注入仅四个特定的模板token来触发的。通过广泛的测试和使用GRPO强化学习训练一个更小的模型，该研究衡量了这些模型的性能、VRAM成本以及潜在的过度思考倾向。 AI

影响揭示了AI推理是由简单的token注入触发的，这可能会影响开发人员设计和优化LLM交互的方式。

Why AI Says “Wait”: How Thinking Models Actually Work (Every Step Measured)

<h4>Toggling “Thinking Mode” doesn’t boot up a second reasoning brain — it injects just 4 template tokens (<think>\n\n</think>\n\n). We ran 696+ completions on Qwen3-4B and trained a 0.6B model with GRPO reinforcement learning to measure how reasoning LLMs actually wo…
