Elastic introduces **ES|QL COMPLETION**, bringing LLM inference directly into detection queries to add contextual reasoning to behavioral alerts. The article details a correlate–context–reason–filter workflow, step-by-step ES|QL examples (including parsing and confidence thresholds), illustrative TP/FP scenarios (e.g., SCCM/Nessus vs. certutil download and LSASS dump), testing with `ROW`, and deployment/connector requirements, along with prebuilt triage rules for hosts and users.
