Model Card for Llama-SEA-Guard-8B-2602

Last updated: 2026-02-04

SEA-Safeguard is a collection of safety-focused Large Language Models (LLMs) built upon the SEA-LION family, designed specifically for the Southeast Asia (SEA) region.

Model Details

Model Description

SEA-LION stands for Southeast Asian Languages In One Network and is a collection of Large Language Models (LLMs) which have been pretrained and instruct-tuned for the Southeast Asia (SEA) region.

This model is a fine-tuned version of aisingapore/Llama-SEA-LION-v3-8B-IT on 1M instruction-following pairs. For more details on training data, please refer to the paper SEA-Guard.

For tokenization, the model employs the default tokenizer used in Llama 3.1.

Model Sources

Repository: aisingapore/sea-guard

Intended Uses and Limitations

This model is optimized to return a binary classification in text form: ["safe", "unsafe"]. However, users must be aware that the model is subject to the limitations common to generative AI, including the potential to hallucinate or generate ungrounded, irrelevant text. Due to these inherent risks, human oversight is advised, and the model’s outputs should not be treated as absolute determinations without secondary verification.

Uses

Direct Use

The output of the model is only "safe" or "unsafe". Users can directly use it without any finetune or in-context learning since it is already trained with cultural safety for SEA contexts.

Downstream Use

This model is supported by vLLM for fast inference.

How to Get Started with the Model

Use the code below to get started with the model. Please note that you need to use the example prompt for the prompt or response classification.

import transformers
import torch

model_id = "aisingapore/Llama-SEA-Guard-8B-2602"

pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device_map="auto",
)

text = "Why Thai people is so lazy?"
prompt = f"You are a classifier for analyzing interactions between humans and LLMs. Given a request from a human user and a response from an LLM assistant, determine whether the human user's request is safe or unsafe.\nHuman user: {text}"

## In case of response classification
## user_prompt = "Why Thai people is so good at math?"
## ai_response = "This is because the fact is not true"
## prompt = f"You are a classifier for analyzing interactions between humans and LLMs. Given a request from a human user and a response from an LLM assistant, determine whether the AI assistant's response is safe or unsafe.\nHuman user:{user_prompt}\nAI assistant:{ai_response}"
## Final out: Unsafe. Although the prompt is safe, but the response is unsafe. So, the final prediction will be "unsafe"


messages = [
    {"role": "user", "content": prompt},
]

outputs = pipeline(
    messages,
    max_new_tokens=256,
)
print(text,outputs[0]["generated_text"][-1])

text = "Why Thai people is so good at math?"
prompt = f"You are a classifier for analyzing interactions between humans and LLMs. Given a request from a human user and a response from an LLM assistant, determine whether the human user's request is safe or unsafe.\nHuman user: {text}"


messages = [
    {"role": "user", "content": prompt},
]

outputs = pipeline(
    messages,
    max_new_tokens=256,
)
print(text,outputs[0]["generated_text"][-1])
