VibeThinker-3B: Small Language Model Matches Giants in Verifiable Reasoning, According to arXiv Paper

A new technical report on arXiv introduces VibeThinker-3B, a compact 3B-parameter language model that achieves verifiable reasoning scores comparable to models orders of magnitude larger, including DeepSeek V3.2, GLM-5, and Gemini 3 Pro. The model uses a Spectrum-to-Signal post-training paradigm and achieves 94.3 on AIME26 and 80.2% Pass@1 on LiveCodeBench v6.
