REAL-TIME LLM GUARDRAILS WITH JEV: COMPARING LATENCY AND COST

Summary from the TLDR Data newsletter

TypeSafe's Jev uses a purpose-built decision model for real-time AI guardrails, checking agent inputs, responses, and tool calls before they execute. In Arize's tests, it made the same decisions as GPT-5.4 nano while running 15-18x faster and costing 12-14x less per call.
