VibeThinker-3B Matches Large Models on Math and Coding Benchmarks

Sina Weibo released VibeThinker-3B, a 3-billion-parameter open model that performs on par with models up to 333 times larger on math and coding tasks. The results stem from multi-stage post-training rather than increased scale. The work supports the view that reasoning skills can be compressed into smaller models while broad factual knowledge cannot.
