Nanbeige4.2-3B: Unlocking Agentic Capabilities in a Compact Model

Nanbeige Lab, :, Chen Yang +23

We present Nanbeige4.2-3B, a compact general agentic model with 3B non-embedding parameters. It delivers strong performance across code-agent, office-agent, and complex tool-use ta…

PACE: Prefix-Protected and Difficulty-Aware Compression for Efficient Reasoning

Ruixiang Feng, Yuntao Wen, Silin Zhou +14

Language Reasoning Models (LRMs) achieve strong performance by scaling test-time computation but often suffer from ``overthinking'', producing excessively long reasoning traces tha…

Measuring and Mitigating Post-hoc Rationalization in Reverse Chain-of-Thought Generation

Guangyue Peng, Zongchao Chen, Wen Luo +9

Reverse Chain-of-Thought Generation (RCG) synthesizes reasoning traces from query-answer pairs, but answer-visible generation can justify a pre-committed answer rather than derive…

Beyond Superficial Forgetting: Thorough Unlearning through Knowledge Density Estimation and Block Re-insertion

Feng Guo, Yuntao Wen, Shen Gao +2

Machine unlearning, which selectively removes harmful knowledge from a pre-trained model without retraining from scratch, is crucial for addressing privacy, regulatory compliance,…
