Deterministic vs Agentic: The Quiet Architectural Bet Every AI Agent Company Is Making

Deterministic vs Agentic AI Architectures: Companies are making a quiet bet between two AI agent architectures. Fat harness (agentic) is suitable for novel, open-ended, or impossible-to-script tasks, while thin harness (deterministic) is better for repetitive, predictable tasks. This decision affects costs, reliability, and long-term viability. Companies should choose the right architecture for their specific use case.
