An overall error rate can hide failures isolated to one model version, retrieval service, or external tool. Checks to make Tag telemetry with safe model, deployment, and dependency identifiers; segment error, timeout, and latency metrics; and alert on meaningful changes. Avoid logging prompt contents by default, and keep correlation IDs for...
An index rebuild can change which passages are retrieved and affect answers even when prompts and model versions remain unchanged. Checks to make Record index version and source snapshot, compare retrieval results on a fixed evaluation set, and measure answer grounding and latency. Stage the new index and keep a rollback option if citation or task...
A model artifact alone may not reproduce outputs if preprocessing, feature definitions, or reference datasets change. Checks to make Record model version, preprocessing code, feature schema, relevant data snapshot or window, and runtime dependencies. Verify release metadata at serving time and keep prior dependency versions available for investigation...
A feature definition change can alter model inputs even when the serving artifact is unchanged. Checks to make Version feature logic, compare distributions and null rates before and after, validate offline and online transformations, and segment performance by use case. Keep the prior feature definition available for controlled comparison or rollback....
Changing endpoint, region, or serving stack can alter latency, configuration, safety controls, or model version. Checks to make Record endpoint and deployment identifiers, compare responses on a fixed evaluation set, and monitor error, latency, and output quality after staged traffic. Verify timeout, access, and fallback behavior before switching all...
If a retrieval source is down, an assistant may return incomplete answers or fall back to stale information. Checks to make Monitor source availability and freshness, define whether to fail closed or provide a limited response, and surface the degraded state to users. Test dependency outage behavior and prevent fallback from silently presenting stale...
A provider outage in one region can affect inference while other regions or model endpoints remain available. Checks to make Track availability and latency by endpoint and region, define safe fallback behavior, and verify data residency and model equivalence before failover. Exercise provider outage scenarios and communicate degraded capabilities...
A retrieval-based assistant can answer without adequate source references after indexing or prompt changes. Checks to make Track citation coverage by task and model version, define when an answer must abstain, and sample missing-citation outputs against source availability. Test source removal and permission filters to ensure citations do not reference...
