Nanbeige发布开放权重教师模型
Nanbeige 以 Apache 2.0 许可证发布 Nanbeige4.3-33B，并将其定位为更小型智能体的教师模型，未来计划中的 Nanbeige4.3-3B 也在该路线之内。模型卡列出 512K 上下文窗口；Nanbeige 称其在相同设置下的 Terminal-Bench 2.1 成绩为 80.9，高于 Qwen3.8-27B 的 73.0。这些成绩尚无独立复现，且其 SWE-Bench Pro 成绩为 60.3，低于 Qwen3.8-27B 的 61.7。
此次发布为开放权重生态增加了一个采用宽松许可证的约 30B 参数教师模型，也为 Nanbeige 后续小型智能体模型奠定基础，但其基准领先幅度仍仅来自厂商评测。
Nanbeige released Nanbeige4.3-33B as the teacher for its planned smaller agents, including an upcoming 3B model. the weights are Apache 2.0, and the model card lists a 512K context window.
the team reports 80.9 on Terminal-Bench 2.1 versus 73.0 for Qwen3.8-27B, using the same harness and inference settings within each benchmark. it does not win everywhere. on SWE-Bench Pro, the reported scores are 60.3 versus 61.7. these are the releasing team's evaluations, not independent replication.
one practical detail for reproducing the agent results: the evaluations retain earlier reasoning with preserve_thinking=true. the card recommends that setting for multi-turn tool use, but not general chat. comparing task success and total generated tokens with that setting held fixed would be more useful than treating the headline scores as a deployment ranking.
