Nanbeige4.3-33B
Nanbeige released Nanbeige4.3-33B on Hugging Face under Apache 2.0, a 33B model with a 512K token context window aimed at agentic coding.
It is the large model of a planned family, which will later be distilled into smaller models as Nanbeige did with its 3B line earlier this year. Per its own model card it scores 65.5 on DeepSWE against 42.5 for Qwen3.8-27B. It trails Qwen narrowly on SWE-Bench Pro and trails Gemma4-31B on GPQA Diamond.
