API-Driven Monitors

October 30, 2025 We now have API-Triggered Monitors: A monitor type that only evaluates when triggered via API call, instead of on a fixed schedule. Ideal for teams running evaluations after events like batch ingestions, model retraining, or CI/CD workflows.

​

Automatic Threshold Ranges for Monitors

October 30, 2025 You can now set upper and lower bounds using our new Auto Threshold options! Arize can automatically determine the right threshold for your alerts based on your historical data. This is ideal for most users who want to start monitoring without manually tuning thresholds.

​

Data Fabric

October 29, 2025 We’re excited to introduce Data Fabric, a new capability that automatically synchronizes production trace data, evaluations, and annotations from Arize into your cloud data warehouse every 60 minutes in Iceberg format—giving you an always-current, query-ready source of truth.

​

New Timeline Tab for Traces

October 28, 2025 You can now see a timeline view when you click into a trace! The new timeline view is right next to the Trace Tree and Agent Graph tabs, and it shows the execution flow and duration of each span.

​

Tags

October 24, 2025 Tags are a lightweight way for you to organize and label your entities across the Arize Platform. You can use tags to:

• Describe source (from-prod, EHR-record)
• Encode purpose (ab-test, regression-test)
• Indicate readiness (golden, deprecated)
• Group by config (threshold-0.85, cohort_5)

Tags live at the Space level, under Space Settings. They can be reused across entities that belong to that space (Datasets, Experiments, and more). More on Tags.

Sort Datasets and Experiment Listing Table

October 22, 2025 You can now sort your datasets and experiments by name, number of experiments, creation date, and more!

​

Support for Tool Call IDs in OpenInference Messages

October 15, 2025 This update introduces full support for tool_call_id and tool_call.id in OpenInference message semantics. These identifiers are now stored alongside input and output messages. Tool call IDs now appear in the trace slideover’s input/output and attributes tabs.

​

Add Data Region to Login Page

October 14, 2025 We’ve added a Data Region selector to the login page, allowing users to choose their preferred data region during sign-in. This helps ensure compliance and improved performance based on regional data needs.

​

Add Auth Failures to Tracing

October 13, 2025 This release adds tracing for authentication failures, enabling better visibility and debugging of auth-related issues across systems.

​

Total Traces on Stats Bar

October 12, 2025 Your projects now display the total number of traces directly in the Stats Bar at the top for quicker visibility into overall activity.

​

Support for GPT OSS Models on Bedrock

October 10, 2025 We’ve added support for GPT open-source models available on Bedrock — try them out now in the Prompt Playground!

​

Expanded LLM Support

October 5, 2025 Expanded LLM model support to include Claude models on Bedrock and Vertex, Titan Text Premiere, Amazon Nova Premiere, Gemini 2.5 Flash/Pro, and new GPT OSS and DeepSeek models —offering broader coverage across top providers.

​

Dashboard Widget Time Setting

October 3, 2025 You can now define time settings per widget in dashboards! This enhancement adds flexibility by letting you set custom time ranges at the widget level — without losing the ability to apply a global dashboard time range. It’s a powerful way to dig deeper into data and run more tailored analyses.

​

Autocomplete for Annotations on Datasets

October 1, 2025 You can now autocomplete annotation variables when editing eval templates in the playground or directly from dataset slideovers. This makes building and managing evals faster and more intuitive.
