Metin/LLaMA-3-8B-Math-Majority-Vote-GRPO is a Test Time Reinforcement Learning (TTRL) trained version of ytu-ce-cosmos/Turkish-Llama-8b-DPO-v0.1. It is trained on Turkish math word problems using GRPO method and a majority vote reward function.

Training Info

Base Model: Turkish-Llama-8b-DPO-v0.1
Training Data: 2.000 open-ended math word problems. No proprietary data was included.
Training Time: 13 hours on a single L40S
LoRA Configs:
- lora_r: 16
- lora_alpha: 16
- lora_dropout: 0
- lora_target_linear: true

The goal was to train a model without using any labels or ground truth answers that can reason before generating the answer. It uses the below template:

xml

<mantık>
...
</mantık>
<cevap>
</cevap>

How to use

Install vLLM

pip install vllm

python

from vllm import LLM, SamplingParams
import json

llm = LLM(model="Metin/LLaMA-3-8B-Math-Majority-Vote-GRPO")

sampling_params = SamplingParams(temperature=0.5)

SYSTEM_PROMPT = """
Sana verilen matematik problemi hakkında düşün ve çözümü bul.
Düşüncelerini <mantık> ve </mantık> arasına yaz.
Sonucu ise <cevap> ve </cevap> arasına yaz. Sonucu yazarken sadece rakamları, noktayı ve virgülü kullan. Noktayı binlik ayracı, virgülü ise ondalık ayracı olarak kullanmalısın. Örnek: <cevap>1.450,02</cevap>
"""

conversation = [
  {
      "role": "system",
      "content": SYSTEM_PROMPT
  }
  {
      "role": "user",
      "content": "Nüfus 20.000'dir. Nüfus her yıl %10 artmaktadır. Buna göre üç yıl sonra nüfus kaç olur?"
  }
]

outputs = llm.chat(
  conversation,
  sampling_params=sampling_params,
  use_tqdm=False
)

result = json.loads(outputs[0].outputs[0].text)

print(result)
