Arize:Observe Unstructured, the first summit dedicated to unstructured data initiatives, recently concluded with nearly 500 technical leaders and practitioners in attendance. The event highlighted four key takeaways: monitoring of unstructured data has arrived; what works in training may not work in production when deciding what to label next; the rise of single, unified models will change MLOps; and cutting-edge machine learning is becoming more accessible. Arize's support for embedding analysis and drift monitoring is now available as part of its free subscription tier, enabling teams to log models with both structured and unstructured data for monitoring purposes.
