Llama-3-Typhoon-1.5X-70B-instruct: Thai Large Language Model (Instruct)

Llama-3-Typhoon-1.5X-70B-instruct is a 70 billion parameter instruct model designed for Thai 🇹🇭 language. It demonstrates competitive performance with GPT-4-0612, and is optimized for application use cases, Retrieval-Augmented Generation (RAG), constrained generation, and reasoning tasks.

Built on Typhoon 1.5 70B (not yet released) and Llama 3 70B Instruct. this model is a result of our experiment on cross-lingual transfer. It utilizes the task-arithmetic model editing technique, combining the Thai understanding capability of Typhoon with the human alignment performance of Llama 3 Instruct.

Remark: To acknowledge Meta's efforts in creating the foundation model and comply with the license, we explicitly include "llama-3" in the model name.

Model Description

• Model type: A 70B instruct decoder-only model based on the Llama architecture
• Requirement: Transformers 4.38.0 or newer
• Primary Language(s): Thai 🇹🇭 and English 🇬🇧
• License: Llama 3 Community License

Performance

We evaluated the model's performance in Language & Knowledge Capabilities and Instruction Following Capabilities.

• Language & Knowledge Capabilities:
  • Assessed using multiple-choice question-answering datasets such as ThaiExam and MMLU.
• Instruction Following Capabilities:
  • Evaluated based on beta users' feedback, focusing on two factors:
    • Human Alignment & Reasoning: Ability to generate responses that are clear and logically structured across multiple steps.
      • Evaluated using MT-Bench — How LLMs can align with human needs.
    • Instruction-following: Ability to adhere to specified constraints in the instructions.
      • Evaluated using IFEval — How LLMs can follow specified constraints, such as formatting and brevity.
• Agentic Capabilities:
  • Evaluated in agent use-cases using Hugging Face's Transformer Agents and the associated benchmark.

Remark: We developed the Thai (TH) pairs by translating the original datasets into Thai through machine and human methods.

ThaiExam

** We report the MMLU score that is reported in GPT-4o Tech Report.

MT-Bench

IFEval

• We report the number from IFEval paper.

Agent

Insight

We utilized model editing techniques and found that the most critical feature for generating accurate Thai answers is located in the backend (the upper layers of the transformer block). Accordingly, we incorporated a high ratio of Typhoon components in these backend layers to enhance our model’s performance.

Usage Example

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "scb10x/llama-3-typhoon-v1.5x-70b-instruct"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
) # We don't recommend using BNB 4-bit (load_in_4bit) here. Instead, use AWQ, as detailed here: https://huggingface.co/scb10x/llama-3-typhoon-v1.5x-70b-instruct-awq.

messages = [...] # add message here

input_ids = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    return_tensors="pt"
).to(model.device)

terminators = [
    tokenizer.eos_token_id,
    tokenizer.convert_tokens_to_ids("<|eot_id|>")
]

outputs = model.generate(
    input_ids,
    max_new_tokens=512,
    eos_token_id=terminators,
    do_sample=True,
    temperature=0.4,
    top_p=0.95,
)
response = outputs[0][input_ids.shape[-1]:]
print(tokenizer.decode(response, skip_special_tokens=True))

Chat Template

We use the Llama 3 chat template.

{% set loop_messages = messages %}{% for message in loop_messages %}{% set content = '<|start_header_id|>' + message['role'] + '<|end_header_id|>\n\n'+ message['content'] | trim + '<|eot_id|>' %}{% if loop.index0 == 0 %}{% set content = bos_token + content %}{% endif %}{{ content }}{% endfor %}{% if add_generation_prompt %}{{ '<|start_header_id|>assistant<|end_header_id|>\n\n' }}{% endif %}

Intended Uses & Limitations

This model is experimental and might not be fully evaluated for all use cases. Developers should assess risks in the context of their specific applications.
