A 33B open model built for agentic coding
The Nanbeige team published Nanbeige4.3-33B on Hugging Face in late October. It is a 33-billion-parameter model under the Apache 2.0 licence, with a 512K-token context window, built for agentic coding and office-style tasks.
The model card reports 80.9 on Terminal-Bench 2.1, against 73.0 for Qwen3.8-27B. These are the team's own evaluations and have not been independently checked.
What makes this one interesting is the size. An agent that writes code and calls tools needs a model you can afford to run all day, and a model in the 30B class is small enough to run outside the biggest data centres.
