VibeThinker 3B model surpasses Opus 4.5 in reasoning with novel SFT+GRPO

A new 3-billion parameter model named VibeThinker has demonstrated superior reasoning capabilities compared to Anthropic's Opus 4.5. This performance was achieved using a novel combination of supervised fine-tuning (SFT) and a technique referred to as GRPO. The findings are detailed in a paper available on arXiv. AI

IMPACT This research suggests smaller models can achieve competitive reasoning abilities, potentially lowering the cost and accessibility of advanced AI.

RANK_REASON The cluster reports on a new research paper detailing a novel AI model and its benchmark performance.
