SEA-LION-7B-Instruct

SEA-LION is a collection of Large Language Models (LLMs) which has been pretrained and instruct-tuned for the Southeast Asia (SEA) region. The sizes of the models range from 3 billion to 7 billion parameters.

SEA-LION-7B-Instruct is a multilingual model which has been fine-tuned with thousands of English and Indonesian instruction-completion pairs alongside a smaller pool of instruction-completion pairs from other ASEAN languages. These instructions have been carefully curated and rewritten to ensure the model was trained on truly open, commercially permissive and high quality datasets.

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

Model Details

Base model

We performed instruction tuning in English and Indonesian on our pre-trained SEA-LION-7B, a decoder model using the MPT architecture, to create SEA-LION-7B-Instruct.

Benchmark Performance

We evaluated SEA-LION-7B-Instruct on the BHASA benchmark (arXiv and GitHub) across a variety of tasks.

BHASA stands out amongst other evaluations for SEA languages for its holistic approach to evaluation, including not just traditional Natural Language Processing (NLP) benchmarking tasks (such as sentiment analysis and question answering), but also linguistic and cultural diagnostic tests which are meticulously handcrafted.

The evaluation was done zero-shot with Indonesian prompts and only a sample of 100-1000 instances for each dataset was used as per the setting described in the BHASA paper. The scores shown in the table below have been adjusted to only consider answers provided in the appropriate language.

Model	QA (F1)	Sentiment (F1)	Toxicity (F1)	Eng>Indo (ChrF++)	Indo>Eng (ChrF++)	Summary (ROUGE-L)	NLI (Acc)	Causal (Acc)

• For Natural Language Understanding (NLU) tasks, we tested the model on Sentiment Analysis (Sentiment) using the NusaX dataset, Question Answering (QA) using the TyDiQA dataset, and Toxicity Detection (Toxicity) using the Indonesian Multi-Label Hate Speech Detection dataset. The metrics used are F1 scores for all three tasks.
• For Natural Language Generation (NLG) tasks, we tested the model on Machine Translation from English to Indonesian (Eng>Indo) and from Indonesian to English (Indo>Eng) using the FLORES-200 dataset, and Abstractive Summarization (Summary) using the XLSum dataset. The metrics used for Machine Translation and Abstractive Summarization are ChrF++ and ROUGE-L respectively.
• For Natural Language Reasoning (NLR) tasks, we tested the model on Natural Language Inference (NLI) using the IndoNLI lay dataset and on Causal Reasoning (Causal) using the XCOPA dataset. The metrics are based on accuracy for both tasks.

Usage

SEA-LION can be run using the 🤗 Transformers library

# Please use transformers==4.37.2

from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("aisingapore/sea-lion-7b-instruct", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("aisingapore/sea-lion-7b-instruct", trust_remote_code=True)

prompt_template = "### USER:\n{human_prompt}\n\n### RESPONSE:\n"
prompt = """Apa sentimen dari kalimat berikut ini?
Kalimat: Buku ini sangat membosankan.
Jawaban: """
full_prompt = prompt_template.format(human_prompt=prompt)

tokens = tokenizer(full_prompt, return_tensors="pt")
output = model.generate(tokens["input_ids"], max_new_tokens=20, eos_token_id=tokenizer.eos_token_id)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Caveats

It is important for users to be aware that our model exhibits certain limitations that warrant consideration. Firstly, 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 in its reasoning. Finally, it should be noted that the model has not been optimized for multi-turn dialogue interactions, which may result in reduced effectiveness in extended conversations.

Limitations

Safety

Current SEA-LION models, including this commercially permissive release, have 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 claim, damages, or other liability arising from the use of the released weights and codes.

Commercially Non-Permissive and Commercially Permissive SEA-LION Releases

The previous release of the commercially non-permissive SEA-LION-Instruct-Research enabled us to explore the full research potential of SEA-LION when allowed to take full advantage of what is publicly available. In contrast, in building the commercially permissive SEA-LION-7B-Instruct, we had to leave out high-quality instruction data that was either proprietary, restricted by non-commercial licenses or in a legal gray area, leaving us with a much smaller proportion of commercially permissive data to work with — a problem that is even more pronounced for low-resource languages. We thus hope this will sound a call to action for more initiatives to create commercially viable data in the region, enabling practical benefits for all.

Technical Specifications

Fine-Tuning Details

The SEA-LION-7B-Instruct was fine-tuned using 8x A100-40GB using parameter efficient fine tuning in the form of LoRA.

Data

SEA-LION-7B-Instruct was trained on a wide range of instructions that were manually and stringently verified by our team. A large portion of the effort was dedicated to ensuring that each instruction-completion pair that the model sees is of a high quality and any errors were corrected and rewritten by native speakers or else dropped from our mix.

In addition, special care was taken to ensure that the datasets used had commercially permissive licenses through verification with the original data source.
