VibeThinker 3B model surpasses Opus 4.5 in reasoning benchmarks

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

IMPACT This research could indicate a trend towards highly capable smaller models, potentially reducing computational costs for advanced reasoning tasks.
