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.
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 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
