## Summary

Nanbeige announced the Nanbeige4.3-33B model, a high‑capacity teacher designed to seed a pipeline that distills agentic abilities into smaller models such as a forthcoming 3B version. The 33B‑parameter model aims to set a new performance bar among open models in the ~30B parameter class, excelling at complex coding and professional cowork tasks.

The team evaluated Nanbeige4.3-33B against frontier models Qwen3.8-27B, Muse‑Glimmer‑30B and Gemma4‑31B using a suite of benchmarks that include Terminal‑Bench, DeepSWE, SWE‑Atlas‑QnA, NL2Repo, Automation Bench v1.0.6 (600 public tasks), JobBench (35 occupations), GDPval, Claw‑Eval General (157 tasks), Toolathlon‑Verified, YC‑bench (10 recent turns) and others. The model led on most tests and showed strong multi‑turn tool‑use performance when the “preservethinking” flag is enabled. It supports a context window of up to 524,288 tokens and can be run with Transformers, SGLang or vLLM.

## Key points

- Nanbeige4.3-33B is a 33B‑parameter teacher model targeting lightweight agent distillation.
- It outperforms Qwen3.8-27B, Muse‑Glimmer‑30B and Gemma4‑31B on most benchmarks, including 35 occupations in JobBench.
- The model supports up to 524,288 tokens and can be served via Transformers, SGLang or vLLM.

## Why it matters

A strong open‑weight 33B teacher model gives researchers and developers a new baseline for building cost‑effective, high‑performing agentic systems without relying on proprietary frontier models.
