Nanbeige4.3-33B

A 33B dense open-weight model for agentic coding and office tasks, under Apache 2.0.

The Nanbeige team published Nanbeige4.3-33B on October 24, 2026. Context is up to 524,288 tokens (512K). It runs with Transformers, SGLang, or vLLM. The BF16 checkpoint is about 66.3 GB. Community GGUF quants exist, including a bartowski Q4_K_M of about 20.79 GB. It is a dense model, so it needs to fit in memory for speed. It is the teacher model for a planned smaller Nanbeige4.3-3B. No date is set for that smaller model. Published benchmarks are lab-reported. We are not reprinting scores.
