Sina Weibo has released VibeThinker-3B, an open-source model with only three billion parameters. Despite its small size, it performs comparably to much larger models like DeepSeek V3.2 and Kimi K2.5 on math and coding tasks. Researchers attribute this efficiency to a multi-stage post-training process, leading to a hypothesis that logical reasoning can be effectively compressed into smaller models, while broad factual knowledge cannot.
