Nanbeige4.2-3B GGUF

This repository provides the GGUF conversions of the original Nanbeige/Nanbeige4.2-3B model. All credit for the model architecture and weights belongs to the original Nanbeige team.

Note: This repository contains only GGUF conversions. The original Hugging Face model is Nanbeige/Nanbeige4.2-3B.

Base Model

Original Hugging Face Model

Nanbeige/Nanbeige4.2-3B

This repository does not modify or fine-tune the original model. It simply provides GGUF conversions for running the model locally with llama.cpp and other GGUF-compatible applications.

Available Files

This repository contains the following GGUF files:

You only need to download ONE of these files.

• Download BF16 if you want the highest possible quality and have sufficient GPU memory.
• Download Q4_K_M if you want lower memory usage while maintaining excellent performance.

Important

At the time of publishing, support for the Nanbeige architecture has not yet been merged into the main llama.cpp repository.

Please use the official Nanbeige fork of llama.cpp:

https://github.com/Nanbeige/llama.cpp/tree/nanbeige42

If you build the upstream ggml-org/llama.cpp, you may encounter an error similar to:

unknown model architecture: 'nanbeige'

The Nanbeige fork contains the required architecture support.

Building llama.cpp

Clone the repository:

git clone --recursive -b nanbeige42 https://github.com/Nanbeige/llama.cpp.git
cd llama.cpp

Build:

cmake -B build
cmake --build build -j

---

Running with llama-server

Example:

./build/bin/llama-server \
    -m Nanbeige4.2-3B-Q4_K_M.gguf \
    --host 0.0.0.0 \
    --port 8080 \
    -ngl 999 \
    -c 65536

After starting the server, the OpenAI-compatible API will be available at:

http://localhost:8080

---

Using Hermes

Hermes works well with this model.

1. Start llama-server.
2. Open Hermes.
3. Go to Model Selection.
4. Choose Custom URL.
5. Enter your llama-server endpoint, for example:

http://localhost:8080

Hermes will communicate directly with your local Nanbeige model using the OpenAI-compatible API.

---

Using a Web UI

This model can also be used with web interfaces that support OpenAI-compatible endpoints, including:

• Open WebUI
• Hermes
• Any application compatible with the OpenAI Chat Completions API

Simply configure the application to connect to your running llama-server instance.

Recommended Model

For most users, the recommended file is:

✅ Nanbeige4.2-3B-Q4_K_M.gguf

It provides an excellent balance of:

• Quality
• Speed
• Memory usage
