Testing Non-Deterministic AI Agents: Why Temperature=0 Isn't Enough
Even with temperature=0, LLM outputs vary due to GPU floating-point non-associativity, hardware differences, and provider changes. Exact-string assertions cause flaky tests that erode team trust. Instead, test for structure, fields, and expected effects, not exact wording.

The article correctly identifies a practical pain point, but the solution—testing contracts over exact strings—is well-known; the real challenge is tooling that makes contract-based testing easy.
