Prompt engineering is a lie. Here's what actually works ?
Billions of dollars went into building GPT-4, Claude, and Gemini — but they're built to be generalists. The moment you need an AI agent that ALWAYS responds in JSON, stays in character as a medieval NPC, or follows strict brand guidelines… prompts start failing.
Why? Because prompts can be hacked. Users inject instructions, override your system prompt, and break the experience.
Fine-tuning is different. It rewires the model's parameters — embedding behavior directly into how it thinks. Pair that with techniques like LoRA & QLoRA, and you can fine-tune models on consumer hardware. No data center required.
? Quick rule: Fine-tuning teaches HOW to behave. RAG pulls WHAT to know.
