Aug 4, 2026: Gateway Monitoring & A/B Testing (General availability)¶

Gateway Monitoring & A/B Testing is now generally available. Use gateway model monitors to track drift and performance for inference services behind a Snowflake Gateway, compare baseline and challenger services during live traffic splits, and evaluate results in Snowsight or with SQL.

With this release, you can:

• Create gateway model monitors with CREATE MODEL MONITOR and query drift, performance, and stat metrics with monitor metric functions.
• Compare services during A/B tests using traffic-split gateways and designate a baseline service for drift comparisons.
• Review gateway operational metrics and monitor dashboards in Snowsight, including confidence intervals when supported.
