Sungur-14B

Sungur-14B is a Turkish-specialized large language model derived from Qwen/Qwen3-14B. The model was fine-tuned using suayptalha/Sungur-Dataset, a 41.1k-sample collection of reasoning-focused conversations spanning domains such as mathematics, medicine, and general knowledge. This dataset is entirely in Turkish and was created to enhance native Turkish reasoning ability.

The training process employed 4-bit QLoRA for Supervised Fine-Tuning (SFT), enabling efficient adaptation while preserving the capabilities of the base model.

Sungur-14B is designed for Turkish reasoning and text generation tasks, delivering coherent, context-aware, and logically structured responses. Through its specialized dataset and training pipeline, the model gains strong native reasoning capabilities in Turkish, making it suitable for advanced applications in analytical dialogue, education, and domain-specific problem solving.

This model was trained on 1xB200 GPU. Training took ~3 hours.

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "suayptalha/Sungur-14B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

messages = [
    {"role": "user", "content": "5x + 1 = 16. x'i bul."},
]

inputs = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
    enable_thinking=True
).to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=4096,
    do_sample=True,
    temperature=0.6,
    top_p=0.95,
    top_k=20,
    min_p=0,
    repetition_penalty=1.2,
    eos_token_id=tokenizer.eos_token_id
)

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

"""
<think>
5x + 1 = 16 denklemini çözmek için, x'i izole etmem gerekiyor. İlk olarak, her iki taraftan 1 çıkararak 5x = 15 elde ederim. Sonra, her iki tarafı 5'e bölerim ve x = 3 bulurum.
</think>

  \(5x + 1 = 16\) denklemini çözmek için, \(x\) değişkenini izole etmemiz gerekiyor. İşte adım adım çözüm:

1. **Her iki taraftan 1 çıkarın:**
   \[
   5x + 1 - 1 = 16 - 1
   \]
   \[
   5x = 15
   \]

2. **Her iki tarafı 5'e bölün:**
   \[
   \frac{5x}{5} = \frac{15}{5}
   \]
   \[
   x = 3
   \]

**Sonuç:**
\[
\boxed{3}
"""

By default, Sungur-14B has thinking capabilities enabled. This means the model will use its reasoning abilities to enhance the quality of generated responses. For example, when explicitly setting enable_thinking=True or leaving it as the default value in tokenizer.apply_chat_template, the model will engage its thinking mode. If you do not want thinking you can set enable_thinking=False.

[!NOTE] For thinking mode, use temperature=0.6, top_p=0.95, top_k=20, min_p=0, and repetition_penalty=1.2. DO NOT use greedy decoding, as it can lead to performance degradation and endless repetitions. For non-thinking mode, use temperature=0.7, top_p=0.8, top_k=20, and min_p=0.
