AI Agents' Secret Sauce: How SFT, DPO, RLHF, and RAG Actually Wire the Brain
Picture your AI agent choking on a simple query, spitting nonsense. That's pre-tuning reality. These four techniques—SFT, DPO, RLHF, RAG—fix it, but not without tradeoffs.
⚡ Key Takeaways
- SFT mimics demos but lacks generalization; it's the bare-minimum base.
- DPO streamlines RLHF's mess, but neither fixes LLM reasoning flaws.
- RAG grounds agents in real data—essential, yet embedding quality decides success.
