Why Full Fine-Tuning (Not LoRA)?

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

✅ Better Quality: News classification +318% vs vocabulary expansion
✅ No Inference Overhead: LoRA adds 5-10% latency
✅ Preserves Knowledge: MMLU scores maintained (not degraded)
✅ Production Stability: Single model file, easier deployment
✅ 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
