Nanbeige4.3-33B is a dense 33B model with a 524,288-token context window. It's on Hugging Face under Apache 2.0, so you can use the weights commercially. The team pitches it for coding agents, tool use, and office tasks, and recommends its preserve_thinking option, which keeps earlier reasoning across turns, for multi-turn tool use. In its own comparison it scores 80.9 on Terminal-Bench 2.1 and 65.5 on DeepSWE, ahead of Qwen3.8-27B, though its SWE-Bench Pro score of 60.3 trails Qwen's 61.7. These results are self-reported and not independently verified. A distilled 3B version is planned.
