Sailor is a suite of Open Language Models tailored for South-East Asia (SEA), focusing on languages such as ??Indonesian, ??Thai, ??Vietnamese, ??Malay, and ??Lao. Developed with careful data curation, Sailor models are designed to understand and generate text across diverse linguistic landscapes of SEA region. Built from Qwen 1.5 , Sailor encompasses models of varying sizes, spanning from 0.5B to 7B versions for different requirements. We further fine-tune the base model with open-source datasets to get instruction-tuned models, namedly Sailor-Chat. Benchmarking results demonstrate Sailor's proficiency in tasks such as question answering, commonsense reasoning, and other tasks in SEA languages.

Training details

Sailor is crafted by continually pre-training from language models like the remarkable Qwen 1.5 models, which already has a great performance on SEA languages. The pre-training corpus heavily leverages the publicly available corpus, including SlimPajama, SkyPile, CC100 and MADLAD-400. The instruction tuning corpus are all publicly available including ayacollection, ayadataset, OpenOrca.

By employing aggressive data deduplication and careful data cleaning on the collected corpus, we have attained a high-quality dataset spanning various languages. Through systematic experiments to determine the weights of different languages, Sailor models undergo training from 200B to 400B tokens, tailored to different model sizes. The approach boosts their performance on SEA languages while maintaining proficiency in English and Chinese without significant compromise. Finally, we continually pre-train the Qwen1.5-0.5B model with 400 Billion tokens, and other models with 200 Billion tokens to obtain the Sailor models.

How to run with llama.cpp

# install llama.cpp
git clone https://github.com/ggerganov/llama.cpp.git
cd llama.cpp
make
pip install -r requirements.txt

# generate with llama.cpp
./main -ngl 24 -m ggml-model-Q4_K_M.gguf -p "<|im_start|>question\nCara memanggang ikan?\n<|im_start|>answer\n" --temp 0.7 --repeat_penalty 1.1 -n 400 -e

Change -ngl 24 to the number of layers to offload to GPU. Remove it if you don't have GPU acceleration.

How to run with llama-cpp-python

pip install llama-cpp-python

import llama_cpp
import llama_cpp.llama_tokenizer

# load model
llama = llama_cpp.Llama.from_pretrained(
    repo_id="sail/Sailor-4B-Chat-gguf",
    filename="ggml-model-Q4_K_M.gguf",
    tokenizer=llama_cpp.llama_tokenizer.LlamaHFTokenizer.from_pretrained("sail/Sailor-4B-Chat"),
    n_gpu_layers=40,
    n_threads=8,
    verbose=False,
)

system_role= 'system'
user_role = 'question'
assistant_role = "answer"

system_prompt= \
'You are an AI assistant named Sailor created by Sea AI Lab. \
Your answer should be friendly, unbiased, faithful, informative and detailed.'
system_prompt = f"<|im_start|>{system_role}\n{system_prompt}<|im_end|>"

# inference example
output = llama(
  system_prompt + '\n' + f"<|im_start|>{user_role}\nCara memanggang ikan?\n<|im_start|>{assistant_role}\n",
  max_tokens=256,
  temperature=0.7,
  top_p=0.75,
  top_k=60,
  stop=["<|im_end|>", "<|endoftext|>"]
)

print(output['choices'][0]['text'])
