Model Card for Gemma-SEA-LION-v4-27B-IT-GGUF

Last updated: 2025-08-25

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

As of 25 Aug 2025, Gemma-SEA-LION-v4-27B-IT excels at Southeast Asian (SEA) tasks when compared to other open models with fewer than 200 billion parameters and demonstrates performance comparable to that of larger and top closed models. Gemma-SEA-LION-v4-27B-IT was quantized to create Gemma-SEA-LION-v4-27B-IT-GGUF. Gemma-SEA-LION-v4-27B-IT-GGUF can run on a laptop with Ollama with 16GB of memory.

Gemma-SEA-LION-v4-27B-IT-GGUF inherits Gemma 3’s:

• Large 128K context length

• Image and text understanding capabilities, including document comprehension, visual Q&A, and image-grounded reasoning

• Advanced function calling and structured outputs to allow for seamless integration into larger systems

Model Description

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

Quantization was performed on Gemma-SEA-LION-v4-27B-IT to produce optimized variants that reduce memory requirements while maintaining model quality. These quantized models support inference on a range of consumer-grade GPUs and are compatible with various inference engines.

For tokenization, the model employs the default tokenizer used in Gemma 3 27B Instruct.

• Developed by: Products Pillar, AI Singapore
• Funded by: Singapore NRF
• Model type: Decoder
• Context length: 128k tokens
• Language(s): Burmese, English, Indonesian, Khmer, Lao, Malay, Mandarin, Tagalog, Tamil, Thai and Vietnamese
• License: Gemma Terms of Use
• Quantized from model: Gemma-SEA-LION-v4-27B-IT

This repo contains GGUF format models files for aisingapore/Gemma-SEA-LION-v4-27B-IT

Model Weights included in this repository:

• Gemma-SEA-LION-v4-27B-IT-Q4_K_M
• Gemma-SEA-LION-v4-27B-IT-Q8_0
• Gemma-SEA-LION-v4-27B-IT-BF16
• Gemma-SEA-LION-v4-27B-IT-mmproj

Take note that some GGUFs are split into parts. Most tools such as llama.cpp and those built on it do support split GGUFs, pointing the platform to the first split will be sufficient for it to function. In the event where a merge is necessary, it can be done using llama.cpp's gguf-split: ./gguf-split --merge ./path/to/first-split ./path/to/output-gguf More details: gguf-split guide & README

How to Get Started with the Model

Use the code below to get started with the model using llama.cpp

llama.cpp (text-only)

./llama-cli -hf aisingapore/Gemma-SEA-LION-v4-27B-IT-GGUF -p "Write a poem about Dim Sum in Indonesian."

llama.cpp (image input)

wget https://github.com/bebechien/gemma/blob/main/surprise.png?raw=true -O ~/Downloads/surprise.png
./llama-gemma3-cli -hf aisingapore/Gemma-SEA-LION-v4-27B-IT-GGUF -p "Describe this image in Malay." --image ~/Downloads/surprise.png

Training Details

Training Data

The dataset comprises Burmese, English, Indonesian, Khmer, Lao, Malay, Mandarin, Tagalog, Tamil, Thai and Vietnamese languages, collected from a mixture of sources including web data, code, open-source datasets, and synthetically generated datasets, amounting to a total of 500 billion tokens sampled from our bucket of 1 trillion tokens.

Evaluation

Performance Test Results

Quantized Variant	Model Size (GB)	VRAM Required (GB)	Time to First Token (s)	Tokens per Second
BF16	54.0	71.1	2.03	41.5
Q8_0	28.7	47	3.179	37
Q4_K_M	16.5	35.5	2.645	59.9

Additional Remarks:

• TTFT and Tokens per Second: measured with vllm on localhost and concurrency = 1.

• GGUF served using llama.cpp with the following settings:

  • Offload all layers to GPU, Context Length 128K

• Reported results are the median (p50) values, calculated across 10 requests.

• Input size 4K, output 1K

• Tests conducted on a system with an NVIDIA H100 GPU

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.

Limitations

In terms of vision capability, Gemma-SEA-LION-v4-27B-IT has been trained and fine-tuned exclusively on the text back-end. As a result, its vision capabilities are expected to be comparable to those of Gemma 3 IT 27B, and may not exhibit significant improvements or differences in this area. 🤗 google/gemma-3-27b-it
