Beyond Prompting: Designing LLM Systems for Real Leverage
By
–
Prompting is step 1. Not the game. The real leverage with LLMs comes from systems: → Persistent context
→ Iterative loops
→ Deep reasoning
→ Structured execution Stop asking: “How do I write a better prompt?” Start asking: “How do I design a better system?” That’s the -
