Contextual Bandit Attributes Sync

September 2, 2026

What

Contextual bandit targeting attributes are now kept in sync between the bandit configuration and the bandit analysis query. The stats engine and the bandit detail page now always reflect the same attribute set.

Why

When a bandit query was updated to change which targeting attributes it used, the bandit's displayed attribute list and the stats engine input could diverge. This made it unclear which attributes were actually influencing the model's decisions.

How

Learn more in the GrowthBook Contextual Bandits docs.
