The AI Harness is becoming the real engineering layer.
Everyone is talking about AI Agents.
I think we're missing the more important piece.
The AI Harness.
A lot of people imagine an AI system like this:
Beyond the Model: Building the AI Harness
The AI Harness is becoming the real engineering layer. Everyone is talking about AI Agents. I think...
TL;DRAI
Production AI systems succeed through the AI Harness—context, memory, planning, model routing, orchestration—more than the LLM; infrastructure manages validation and resilience. AI engineering shifts from prompt optimization to software architecture; teams shipping production AI prioritize building reliable, observable harnesses rather than chasing model improvements.
