Nanbeige Releases Nanbeige4.3-33B, a 33B Open Agentic Coding Model

Why it matters

Nanbeige LLM Lab, a research team inside the recruitment platform BOSS Zhipin, has published Nanbeige4.3-33B on Hugging Face under the permissive Apache 2.0 license, alongside a base variant, Nanbeige4.3-33B-Base, intended for custom post-training. The model is a dense architecture built for agentic coding and office-style cowork tasks, with a very long context window and a chat template that supports toggleable reasoning, reasoning preservation across turns, and tool calling. The lab's stated strategy is to build a strong teacher model first, then distill agentic skills into smaller models, beginning with the upcoming Nanbeige4.3-3B. In the lab's own comparison table, the model leads most rows against similarly sized open rivals Qwen3.8-27B, Muse-Glimmer-30B and Gemma4-31B, though all scores are self-reported. Notably, several competitor figures in the table conflict with those labs' own published model cards, so readers should treat the rankings as provisional until independent evaluations appear.
