Final Thoughts
Fine-tuning is a powerful technique that bridges the gap between general-purpose LLMs and specialized AI assistants. With the tools you've learned:
- LoRA makes fine-tuning accessible on consumer hardware
- QLoRA enables training models that previously required enterprise GPUs
- Unsloth cuts training time and costs in half
- DPO aligns models without complex RL pipelines
- Ollama makes deployment as simple as a single command
The key to success is iteration:
- Start with a small dataset
- Train quickly with Unsloth
- Evaluate rigorously
- Improve your data
- Repeat
Remember: Data quality beats quantity. A well-curated dataset of 1,000 examples will outperform 10,000 noisy ones. Focus on your specific use case and iterate based on evaluation results.
Good luck with your fine-tuning journey!
