⚡ Key Takeaways

  • Harper bundles AI agent stack into one runtime: DB, vectors, cache, API, deploy — 5 minutes to live demo.
  • Semantic caching delivers real savings: sub-50ms repeats at $0 LLM cost, compounding at scale.
  • Skeptical win: Echoes Rails simplification, but watch for vendor lock-in on Fabric hosting.
