Nemotron-SEA-LION-v4.8-120B-A12B-GGUF

Last updated: 2026-09-18

This repository contains the GGUF quantized weights for aisingapore/Nemotron-SEA-LION-v4.8-120B-A12B.

The model is optimized for Southeast Asian (SEA) languages, cultures, and contexts. This repository provides quantized models that have significantly compressed memory footprints while preserving model accuracy, enabling low-latency MoE inference across high-throughput production environments.

Model Details

Model Description

SEA-LION stands for Southeast Asian Languages In One Network.

For tokenization, the model employs the default tokenizer used in nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-BF16.

Usage

llama.cpp

You can serve the model using llama.cpp (add other flags to customize your setup):

llama-server -ngl -1 --port 8080 \
    -m /directory/path/to/Nemotron-SEA-LION-v4.8-120B-A12B-Q4_K_M.gguf

You can proceed to make API calls to the model:

curl -X POST http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "Nemotron-SEA-LION-v4.8-120B-A12B-Q4_K_M.gguf",
    "messages": [
        {
        "role": "user",
        "content": "Teach me a greeting in Bahasa Indonesia."
        }
      ],
    "chat_template_kwargs": {
      "enable_thinking": false
      }
  }'

You can also access the UI at http://localhost:8080 to chat with the model directly.

Technical Specifications

Technical Report

For training details, see the SEA-LION-v4.8 Technical Report.

Model Architecture

The architecture is based on the highly efficient Nemotron-3-Super foundation. The detailed architecture can be found at nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-BF16 documentation.

Uses

Out-of-Scope Use

The model has not been aligned for safety. Developers and users should perform their own safety fine-tuning and related security measures. In no event shall the authors be held liable for any claims, damages, or other liabilities arising from the use of the released weights and codes.

Bias, Risks, and Limitations

The model was not tested for robustness against adversarial prompting. It is important for users to be aware that our model exhibits certain limitations that warrant consideration. Like many LLMs, the model can hallucinate and occasionally generates irrelevant content, introducing fictional elements that are not grounded in the provided context. Users should also exercise caution in interpreting and validating the model's responses due to the potential inconsistencies.
