Chinese AI firm Nanbeige Technology has released Nanbeige4.1-3B, a new 3-billion-parameter language model designed for strong performance in both Chinese and English. The model is based on the popular Llama architecture but was trained from scratch on a custom, high-quality dataset of 3.5 trillion tokens.

This release adds a new contender to the growing field of specialized, efficient open models. By focusing on a specific language pair and a compact size, Nanbeige4.1-3B offers developers a capable option that can run on less powerful hardware. The company's provided benchmarks show it performing competitively against other models in its class on Chinese-centric evaluations like CMMLU and C-Eval.

## Key Specifications

The model's technical details make it a practical choice for a range of applications:

*   **Architecture:** Llama
*   **Parameters:** 3 billion
*   **Context Length:** 4096 tokens
*   **Training Data:** 3.5T tokens (Chinese & English)

According to its [Hugging Face release card](https://huggingface.co/Nanbeige/Nanbeige4.1-3B), Nanbeige4.1-3B is available under a custom license that permits free commercial use, an important consideration for teams looking to build products with the model.
