+# News
+🎉 Nanbeige4-3B-Thinking-2511 debuts at #11 on [**WritingBench**](https://huggingface.co/spaces/WritingBench/WritingBench)! Despite only 3B parameters, its creative-writing ability chops rival those of hundred-billion-parameter giants.
+🎉 Nanbeige4-3B-Thinking-2511 ranks #15 on [**EQBench3**](https://eqbench.com/), demonstrating human-preference alignment and emotional intelligence comparable to much larger models.
+# Introduction
+Nanbeige4-3B-Thinking-2511 is an enhanced iteration over our previous Nanbeige4-3B-Thinking-2510.
+Through advanced knowledge distillation techniques and targeted reinforcement learning (RL) optimization, we have significantly scaled the model’s reasoning capabilities, delivering stronger and more reliable performance on diverse challenging benchmarks.
+This version establishes new state-of-the-art (SOTA) results among open models under 32B parameters on AIME, GPQA-Diamond, Arena-Hard-V2, and BFCL-V4, which marks a major milestone in delivering powerful yet efficient reasoning capabilities at a compact scale.

+# <span id="Limitations">Limitations</span>
+While we place great emphasis on the safety of the model during the training process, striving to ensure that its outputs align with ethical and legal requirements, it may not completely avoid generating unexpected outputs due to the model's size and probabilistic nature. These outputs may include harmful content such as bias or discrimination. Please don't propagate such content. We do not assume any responsibility for the consequences resulting from the dissemination of inappropriate information.
