Can a 3B Small Model Match Top Closed‑Source LLMs? VibeThinker-3B’s Limits

VibeThinker-3B, a newly open‑sourced 3‑billion‑parameter model, achieves near‑state‑of‑the‑art scores on math competitions (AIME, IMO‑AnswerBench), coding (LiveCodeBench), and verification benchmarks, rivaling trillion‑parameter closed models, thanks to a Spectrum‑to‑Signal training pipeline, multi‑stage SFT, RL, and offline distillation, supporting a new parametric compression‑coverage hypothesis.
