Karpathy’s March of Nines: 90% Reliability Fails
Andrej Karpathy's 'March of Nines' illustrates why 90% AI reliability is insufficient for production, as each additional nine requires equal effort. In multi-step agentic workflows, failures compound exponentially, demanding 99.99% per-step success for enterprise dependability. The article outlines SLOs and nine levers like workflow graphs to achieve higher reliability.
