Intended Use

This model is intended for various NLP tasks that require understanding and generating Indonesian language. It is suitable for applications such as question answering, sentiment analysis, document summarization, and more.

Training Data

Bahasa-4b was trained on a 10 billion subset data of Indonesian dataset from a collected pool of 100 billion.

Benchmarks

The following table shows the performance of Bahasa-4b compared to the models Sailor_4b and Mistral-7B-v0.1 across several benchmarks:

Dataset	Version	Metric	Mode	Sailor_4b	Bahasa-4b-hf	Mistral-7B-v0.1
tydiqa-id	0e9309	EM	gen	53.98	55.04	63.54
tydiqa-id	0e9309	F1	gen	73.48	75.39	78.73
xcopa-id	36c11c	EM	ppl	69.2	73.2	62.40

from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda" # the device to load the model onto

model = AutoModelForCausalLM.from_pretrained(
    "Bahasalab/Bahasa-4b-chat-v2",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Bahasalab/Bahasa-4b-chat")

messages = [
    {"role": "system", "content": "Kamu adalah asisten yang membantu"},
    {"role": "user", "content": "kamu siapa"}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

model_inputs = tokenizer([text], return_tensors="pt").to(device)

generated_ids = model.generate(
    input_ids=model_inputs.input_ids,
    attention_mask=model_inputs.attention_mask,
    max_new_tokens=512,
    eos_token_id=tokenizer.eos_token_id

)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)

This data demonstrates that Bahasa-4b consistently outperforms the Sailor_4b model in various Indonesian language tasks, showing improvements in both EM (Exact Match) and F1 scores across different datasets, and is competitive with the Mistral-7B-v0.1 model.
