Gemma2 9B WangchanLIONv2 Instruct

WangchanLION is a joint effort between VISTEC and AI Singapore to develop a Thai-specific collection of Large Language Models (LLMs), pre-trained for Southeast Asian (SEA) languages, and instruct-tuned specifically for the Thai language.

Gemma2 9B WangchanLIONv2 Instruct is a multilingual model that has been fine-tuned with around 3,760,000 Thai instruction-completion pairs from human-annotated instructions, automatic data construction in FLAN-style, and synthetic samples.

Model Details

Model Description

We performed instruction tuning in Thai on continued pre-trained Gemma2 9B CPT SEA-LIONv3, a decoder model using the Gemma2 architecture, to create Gemma2 9B CPT WangchanLIONv2 Instruct.

For tokenization, the model employs the default tokenizer used in Gemma-2-9B. The model has a context length of 8192.

Benchmark Performance

We evaluated Gemma2 9B WangchanLIONv2 Instruct in Thai using the Thai LLM Benchmark. The benchmark consists of Thai multiple-choice exams, multi-turn chat, reading comprehension and language generation. The evaluation results are available on the leaderboard.

Usage

NOTE This model has not been trained to use a system prompt or to use tool calling.

Gemma2 9B WangchanLIONv2 Instruct can be run using the 🤗 Transformers library

# Please use transformers==4.45.2

import transformers
import torch

model_id = "aisingapore/Gemma2-9b-WangchanLIONv2-instruct"

pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device_map="auto",
)
messages = [
    {"role": "user", "content": "แต่งกลอนให้หน่อย"},
]

outputs = pipeline(
    messages,
    max_new_tokens=256,
)
print(outputs[0]["generated_text"][-1])

Caveats

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 in its reasoning.

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.

Technical Specifications

Fine-Tuning Details

Gemma2 9B WangchanLIONv2 Instruct was built using parameter-efficient fine-tuning. The training process for fine-tuning was approximately 3 days on 8x H100-80GB GPUs.

The following hyperparameters were used during training:

• quantization_bit: 4
• quantization_method: bitsandbytes
• finetuning_type: lora
• lora_target: all
• cutoff_len: 2048
• per_device_train_batch_size: 4
• gradient_accumulation_steps: 8
• learning_rate: 1.0e-4
• num_train_epochs: 3
• lr_scheduler_type: cosine
• warmup_ratio: 0.1
• bf16: true
• val_size: 0.01
• per_device_eval_batch_size: 1
• eval_strategy: steps
• eval_steps: 4000

We use LLaMA Factory framework for the fine-tuning process.

Data

Gemma2 9B WangchanLIONv2 Instruct was trained on

1. Human-Annotated Thai Instruction Dataset
2. FLAN-like dataset in Thai
3. WangchanX Seed-Free Synthetic Instruct Thai 120k
