# New In Arize AX: Tags, Data Fabric, Automatic Threshold Ranges for Monitors and More - **Published:** 2025-11-04 - **Updated:** 2026-10-08 - **Authors:** Sanjana Yeddula - **Canonical:** --- ![](https://arize.com/wp-content/uploads/2025/12/November-Updates.jpg) October of 2025 was a crowded month for shipping new features in Arize AX, with updates to make AI agent engineering easier. From a new timeline tab for traces to data fabric, there is a lot to catch up on and try out. ## Tags ![arize ax tags in platform](https://arize.com/wp-content/uploads/2025/11/arize-ax-tags-ui.png) Tags are a lightweight way for you to organize and label your entities across the Arize AX 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](https://arize.com/docs/ax/release-notes#tags) live at the `Space` level, under Space Settings. They can be reused across entities that belong to that space (Datasets, Experiments, and more). ## Data Fabric ![arize adb data fabric ](https://arize.com/wp-content/uploads/2025/11/arize-ax-data-fabric.png) We’re excited to introduce [Data Fabric](https://arize.com/docs/ax/security-and-settings/data-fabric), a new capability that automatically synchronizes production trace data, evaluations, and annotations from Arize AX into your cloud data warehouse every 60 minutes in Iceberg format—giving you an always-current, query-ready source of truth. ## Monitors Updates ### Automatic Threshold Ranges for Monitors You can now set upper and lower bounds using our new **[auto threshold](https://arize.com/docs/ax/release-notes#automatic-threshold-ranges-for-monitors)** 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. ### API-Driven Monitors ![](https://arize.com/wp-content/uploads/2025/11/arize-ax-api-driven-monitors.png) Arize AX now has 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. ## Tracing Updates ### New Timeline Tab for Traces ![](https://arize.com/wp-content/uploads/2025/11/tracing-timeline-in-arize-ax.png) You can now see a [timeline view](https://arize.com/docs/ax/release-notes#new-timeline-tab-for-traces) 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. ### Add Auth Failures to Tracing This release adds tracing for authentication failures, enabling better visibility and debugging of auth-related issues across systems. ### Total Traces on Stats Bar ![](https://arize.com/wp-content/uploads/2025/11/arize-ax-total-trace-stats-scaled.png) 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 Tool Call IDs in OpenInference Messages 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 ![](https://arize.com/wp-content/uploads/2025/11/arize-ax-data-region.png) Arize AX now has 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. ## Expanded LLM Support Arize AX now supports 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. We also added Arize AX support for GPT open-source models available on Bedrock — try them out now in the Prompt Playground! ![](https://arize.com/wp-content/uploads/2025/11/arize-ax-gpt-oss-support.png) ## Datasets & Experiments ### Sort Datasets and Experiment Listing Table ![](https://arize.com/wp-content/uploads/2025/11/arize-ax-sort-datasets-and-experiments.png) You can now sort your datasets and experiments by name, number of experiments, creation date, and more! ### Autocomplete for Annotations on Datasets ![](https://arize.com/wp-content/uploads/2025/11/arize-ax-annotation-autocomplete-scaled.png) 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. --- [More blog posts](https://arize.com/blog/sitemap.md)
