Nanbeige's open 33B model scores 80.9 on Terminal-Bench 2.1, ahead of Qwen3.8-27B
Nanbeige released Nanbeige4.3-33B, open weights built as a teacher model whose skills will later be distilled into smaller ones, such as a planned Nanbeige4.3-3B. On Terminal-Bench 2.1, a test of coding agents working in a terminal, it scores 80.9 against 73.0 for Qwen3.8-27B. It is not ahead everywhere: on SWE-Bench Pro it scores 60.3 to Qwen's 61.7.
