- 发生了什么
- Guide comparing five techniques to adapt open weight models: prompt engineering, RAG, supervised fine-tuning, preference optimization, and reinforcement learning.
- 为何重要
- Engineers deploying base models to production need to choose which adaptation strategy fits their accuracy, cost, and freshness requirements.
- 注意
- No single technique solves all problems. RAG fails with poor retrieval, fine-tuning locks in stale facts, and RL requires reliable reward signals or it teaches wrong behavior.
- rag
- prompt
- fine-tun
