2. VibeThinker: A 3B Parameter Reasoning Giant
A new paper on arXiv introduces VibeThinker, a 3-billion-parameter model that achieves superior reasoning performance — reportedly surpassing Claude Opus 4.5 — using a novel combination of supervised fine-tuning (SFT) and Group Relative Policy Optimization (GRPO). The result challenges the assumption that only massive frontier models can excel at complex reasoning tasks, opening the door to efficient, small-footprint reasoning agents.
