The smartest bet in AI right now isn’t the model. It’s the plumbing around it.
We spent 2025 arguing about which LLM was better. GPT-5 vs Claude vs Gemini. Benchmarks, leaderboards, Reddit fights. Underneath all that noise, engineers quietly stopped asking “which model?” and started asking “how do I run 20 of them without losing my mind?” That question is now an infrastructure category. Agent harnesses. And nobody has clean answers yet.
