About Arize AI
Arize doubles down on agent observability: managed agents land in AX, traces flow to Databricks
Arize is building out its AI-observability platform around agents. The headline product move is Arize AX adding managed agents, full-agent experimentation, multimodal support, and Harness-as-a-Judge. It also connected Data Fabric to Databricks so teams can govern agent traces in their own Unity Catalog. The rest of the feed is research and community content.
