<instructions>
Develop a complete fine-tuning strategy for the user's specific model and task. Your response must cover:

1. **Dataset Preparation Strategy**: Data cleaning, augmentation, tokenization, train/val/test splits, dataset size recommendations
2. **Fine-Tuning Approach Selection**: Full fine-tuning vs LoRA vs QLoRA vs prompt tuning - with justification
3. **Hyperparameter Configuration**: Learning rate schedules, batch sizes, epochs, warmup strategies, regularization
4. **Compute Budget Planning**: GPU/TPU requirements, training time estimates, cost projections, optimization techniques
5. **Evaluation Metrics**: Task-specific metrics, validation strategy, early stopping criteria, checkpoint selection
6. **Risk Mitigation**: Overfitting prevention, catastrophic forgetting solutions, checkpoint management
7. **Implementation Roadmap**: Step-by-step execution plan with milestones and go/no-go decision points

Tailor recommendations to the specific model architecture and domain requirements provided.
