Nanbeige4.3-33B

Nanbeige4.3-33B is a 33B-parameter text-generation model from the Nanbeige team, released as the flagship teacher model of the Nanbeige4.3 series. The team plans to use it to distil agentic capabilities into smaller models, such as a Nanbeige4.3-3B. It targets complex coding and professional cowork tasks and supports a context length of up to 524,288 tokens. The team compares it with Qwen3.8-27B, Muse-Glimmer-30B and Gemma4-31B at their highest thinking effort, using the same harness and hyperparameters. It scores 80.9 on Terminal-Bench 2.1 (Qwen3.8-27B: 73.0), 65.5 on DeepSWE (42.5) and 54.2 on Automation Bench (38.3). It trails Qwen3.8-27B on SWE-Bench Pro (60.3 vs 61.7) and GDPval (84.8 vs 86.4), and Gemma4-31B on GPQA Diamond (89.5 vs 91.3). These are the developers' own results. The chat template has switches for thinking mode, for preserving reasoning across turns, and for XML or JSON tool calls. It runs with Transformers, SGLang or vLLM and is released under the Apache-2.0 licence, with English and Chinese listed as languages.
