Nanbeige4.3-33B is an Apache-2.0 open model for agentic coding with a 512K context
The 33B dense model from BOSS Zhipin's Nanbeige lab self-reports 80.9 on Terminal-Bench 2.1 and 65.5 on DeepSWE versus 73.0 and 42.5 for Qwen3.8-27B, though Qwen still edges it on SWE-Bench Pro (61.7 to 60.3). It runs on vLLM or SGLang with Qwen3 tool-call parsing, and the scores are the lab's own, so test it on your repos before swapping your local coding agent (MarkTechPost).
