Compact looped-transformer model of 4.2B parameters for agent work such as tool use, office tasks and coding, in English and Chinese. For developers who want a small open model for agents.

Nanbeige4.2-3B by Nanbeige is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-13. Download it on this page, a zip of its files. Nothing in it runs by itself.

Made by Nanbeige

## About

### What it is

Nanbeige4.2-3B is a compact language model for agent work, built on Nanbeige4.2-3B-Base. It uses a looped transformer that reuses its layers to add capacity without adding parameters. It has 4.2 billion parameters in total and about 3 billion outside the embeddings. It works in English and Chinese.

### Who it suits

It suits developers who want a small open model for tool use, office tasks and coding agents on modest hardware.

| Industry | Who uses it | How they use it | Example |
| --- | --- | --- | --- |
| Software | Agent developers | Power a tool-using or coding agent | Running a code agent on a bug-fix task |
| Office work | Productivity tool makers | Automate document and office tasks | Filling in an office workflow with tools |
| Research | ML researchers | Study looped transformer designs | Comparing it with larger open models |
| Personal tools | Hobbyists | Run a local assistant | Pairing it with an agent scaffold for daily tasks |

You can skip it if you need a huge model for hard open-ended work, since this one is aimed at the 3B scale.

### Where to use it

It runs in Python through the transformers library on Windows, macOS or Linux. The card suggests pairing it with an agent scaffold for personal workflows, naming OpenClaw as one.

- Python scripts that use transformers
- An agent scaffold such as OpenClaw, for personal assistant use
- A local computer, since the weights are small

| Use case | Who | What they get back |
| --- | --- | --- |
| Tool use | Agent builders | Tool-calling behavior on agent benchmarks |
| Code agents | Developers | Fixes tested on software engineering tasks |
| Local assistant | Hobbyists | Help with daily, office and research tasks |

### How to set it up

You need Python and the Hugging Face tool. Hugging Face lists the weights at about 8.3 GB in BF16, or an estimated 2.1 GB at 4-bit. The card's visible part gives no run commands, so follow its usage section.

- Python with transformers
- About 8.3 GB of disk for the BF16 weights
- A GPU for comfortable speed

1. Install the Hugging Face download tool.
2. Download the model files, or let transformers fetch them by name.
3. Load the model and tokenizer, and connect an agent scaffold if you want one.

```bash
pip install -U huggingface_hub
hf download Nanbeige/Nanbeige4.2-3B
```

### How to use it

Load it with transformers for chat, or connect it to an agent scaffold so it can use tools. The repository also ships a Python modeling file that carries the makers' newest architecture changes. Three of them are named LoopSplit, depth-attention mHC and n-gram embeddings.

| Tool | What it does |
| --- | --- |
| hf download | Fetches the model files to your computer |
| transformers | Loads the model for use in Python |
| Agent scaffold | Gives the model tools and a workflow, such as OpenClaw |

### Example

You connect the model to a code-agent scaffold and give it a bug report. It reads the code, calls tools, and proposes a fix, which the scaffold can test.

### For newcomers and experts

If you are new, load the model in transformers and chat with it first. Add an agent scaffold once you are comfortable with the basics.

If you know the field, supervised tuning drew on real and synthesized environments, with filtering by test cases and rubrics. Reinforcement learning mixed outcome and process rewards to keep a small model stable. The looped design reuses layers to grow capacity.

Nanbeige4.2-3B-Base → Supervised tuning on agent environments → Reinforcement learning with outcome and process rewards → Compact agentic model

### Good to know

The makers report higher agent benchmark scores than Gemma4-12B and Qwen3.5-9B, both bigger models. The figures are from their own comparison.

- License: Apache 2.0
- Cost to run: no API key, account or paid service is named
- Data it reaches: the prompts you give it on your machine, plus files downloaded from Hugging Face and whatever your agent scaffold lets it use
- Not for: results beyond what the makers' own benchmarks show
