✅ **Most Cost-Effective**: 40-94% lower production costs  
✅ **Edge-Deployable**: Only Uzbek model under 2GB VRAM  
✅ **Zero Repetition**: Robust generation with optimized parameters  
✅ **Fully Open**: Complete methodology and training code available  

### Key Differentiators

🔸 **vs. Mistral-Nemo-Uz (12B)**: 94% less VRAM, 93% faster, 94% cheaper - same quality within 12%  
🔸 **vs. alloma-1B**: 44% less VRAM, 36% faster, 40% cheaper - quality gap only 8%  
🔸 **vs. Llama-3.2-1B**: 72% less VRAM, 66% faster, better Uzbek understanding

```bash
pip install transformers torch accelerate
```

### Basic Inference (Recommended)

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

# Load model
model_name = "bekhzod-olimov/Qwen3-0.6B-Instruct-Uz"
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_name,

]

# Generate (with optimized parameters)
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=256,
    temperature=0.85,          # 0.7 for factual, 0.85-0.9 for creative
    top_p=0.95,
    repetition_penalty=1.2,    # Prevents repetition (critical!)
    do_sample=True
)

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

- **Size**: 162,508 instruction-response pairs
- **Quality**: Deduplicated, cleaned, validated
- **Languages**: Uzbek (Cyrillic & Latin mix), English
- **Domains**: Conversation, general knowledge, culture, reasoning, task completion

### Training Configuration

```yaml
base_model: Qwen/Qwen2.5-0.5B-Instruct
method: Full fine-tuning (not LoRA)
trainable_params: 596,049,920 (100%)
optimizer: AdamW
learning_rate: 2e-5
batch_size: 4
gradient_accumulation: 4
effective_batch_size: 16
max_steps: 27,426
early_stopping: checkpoint-26000 (optimal)
warmup_steps: 500
weight_decay: 0.01
max_seq_length: 2048
precision: bfloat16
hardware: NVIDIA RTX 4090 (24GB)
training_time: ~36 hours
framework: Transformers + PyTorch
```

### Why Full Fine-Tuning (Not LoRA)?

We chose full fine-tuning over LoRA or vocabulary expansion because:

1. ✅ **Better Quality**: News classification +318% vs vocabulary expansion
2. ✅ **No Inference Overhead**: LoRA adds 5-10% latency
3. ✅ **Preserves Knowledge**: MMLU scores maintained (not degraded)
4. ✅ **Production Stability**: Single model file, easier deployment
5. ✅ **Better Convergence**: Direct optimization of all parameters

## ⚠️ Limitations

### Known Issues

**1. Q&A Accuracy Under Investigation**
- Current benchmark shows 26.7% success rate (investigation ongoing)
- Previous tests showed 76-100% success
- Likely chat template application issue
- **Workaround**: Adjust prompt format based on your specific use case

**2. Translation Quality Gap (Expected)**
- BLEU scores 30-40% below 1B+ models
- Expected limitation for 0.6B parameters
- **Use Case**: Focus on conversation, not professional translation

**3. Knowledge Breadth Limited**
- MMLU ~25-37 vs 40+ for larger models
- Size-constrained encyclopedic knowledge
- **Use Case**: Conversational tasks, not knowledge queries

### Not Suitable For

- ❌ Professional translation services
- ❌ Medical/legal/financial advice
- ❌ High-stakes decision making
- ❌ Complex multi-step reasoning
- ❌ Encyclopedic knowledge queries

### Potential Biases

- Trained on publicly available Uzbek data (2023-2024)
- May reflect dataset biases and limitations
- Better on standard/urban Uzbek vs regional dialects
- Cultural context snapshot from training period
