# mongolian-mistral-7b-chatbot

## Description
Mistral 7B fine-tuned on Mongolian news data for chatbot

## Model Details
- **Base Model:** mistralai/Mistral-7B-Instruct-v0.2
- **Language:** Mongolian (mn)
- **Fine-tuning Method:** LoRA (Low-Rank Adaptation)
- **Training Data:** Eduge Mongolian News Dataset (75,000+ articles)

## Training Configuration
- **LoRA Rank:** 32
- **LoRA Alpha:** 64
- **Epochs:** 3
- **Learning Rate:** 2e-4
- **Batch Size:** 4
- **Max Sequence Length:** 1024

## Mongolian Tokens Added
- Total new tokens: ~9,500
- Sources: Mongolian-NLP repository
  - Most frequent words
  - Abbreviations
  - District/place names
  - Country names
  - Named entities (NER)

## Usage
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("ErkaMarka/mongolian-mistral-7b-chatbot")

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "mistralai/Mistral-7B-Instruct-v0.2",
    torch_dtype=torch.float16,
    device_map="auto"
)

# Resize embeddings for new tokens
base_model.resize_token_embeddings(len(tokenizer))

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "ErkaMarka/mongolian-mistral-7b-chatbot")

# Generate
messages = [{"role": "user", "content": "Монгол улсын нийслэл хот юу вэ?"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=150)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

## Evaluation Results
Evaluated on 100 Mongolian Q&A pairs using BLEU score.
