# Qwen3-8B-ru

- [EN]  
Qwen3-based model, adapted for russian text generation tasks.  
- [RU]  
Finetune версия Qwen3, адаптированная для генерации русского текста.  

## Model Details / Детализация модели
- [EN]  
LoRA supervised finetuning was performed on 2xA100 NVIDIA GPUs for 12h for 1 epoch on datasets:  
attn-signs/kolmogorov-3;  
attn-signs/russian-code;

- [RU]  
LoRA SFT цикл был выполнен на двух NVIDIA A100, обучение длилось около 12 часов.  
Прогон полной эпохи датасетов:  
attn-signs/kolmogorov-3;  
attn-signs/russian-code;


### Model Description / Описание модели

- **Developed by:** [Reisen Raumberg (Attention Signs team)]
- **Language(s) (NLP):** [RU/EN]
- **Finetuned from model:** [Qwen3]

Utilized DeepSpeed (Stage 3), HF.Accelerator for distributed training and fused AdamW.  
**GPU hours**: 12h of NVIDIA A100

Для обучения использовались HuggingFace Accelerator с Microsoft DeepSpeed (Stage 3) для распределения параметров и стейта оптимизатора, а так же зафьюженный AdamW  
**GPU часы**: 12 часов NVIDIA A100

### Usage / Использование модели
```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "attn-signs/Qwen3-8B-ru"

# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)

# prepare the model input
prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=True # Switches between thinking and non-thinking modes. Default is True.
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

# conduct text completion
generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=32768
)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist() 

# parsing thinking content
try:
    # rindex finding 151668 (</think>)
    index = len(output_ids) - output_ids[::-1].index(151668)
except ValueError:
    index = 0

thinking_content = tokenizer.decode(output_ids[:index], skip_special_tokens=True).strip("\n")
