What are the fundamental system invariants in production LLMOps systems?

System invariants in LLMOps are guarantees like safety constraints, cost ceilings, latency bounds, and output format validity that must always hold.

Unlike traditional systems where correctness is binary, LLMOps defines invariants as constraints that must never be violated under any load condition. These include safety (no toxic output), structural correctness (valid schema), cost limits (token budgets), and latency SLOs. The architecture is designed so that even when the model fails, invariants are enforced by guardrails, fallback systems, or blocking mechanisms.
