Alyx: Arize AX's AI engineering agent

Alyx home screen with greeting, chat input, model selector, and suggested actions including quickstarts for tracing, playground, and evaluators

Where to find Alyx

Alyx is a built-in AI agent that works wherever you are in the platform. Your conversation carries over between pages and tasks, so you can go from a trace to the playground to an experiment without losing context. Behind the scenes, Alyx loads the right skills, instructions, and tools on demand for the surface you’re on, which keeps responses fast and focused as its capabilities grow. Alyx appears in two forms that share the same conversation:

Home view: the full-page experience on the Arize AX home page. Use it to start or resume a conversation, browse suggested workflows, and pick up a previous thread from your history. It is the place to begin broad or return to earlier work.
Side chat: a panel you open over any page with the keyboard shortcut. It inherits the context of whatever you are viewing, such as a project, trace, dataset, or experiment, so you can ask about the data in front of you and let Alyx act on it without leaving the page. Dock it to the right as a resizable sidebar or detach it as a floating window. When you open it from a trace, it scopes to that trace and its spans.

Each surface loads the skills relevant to the task at hand:

Surface	How to open	Skills available
Arize AX home	Full-page Alyx on the home page	Full skill set across observe, evaluate, and improve
Trace slideover	Open Alyx from a trace detail view	Trace troubleshooting, span analysis, annotations, build evals
Prompt Playground	Alyx chat in the Playground	Optimize prompts, build evals, run experiments
Eval Builder / Task Builder	Alyx on the eval or task builder page	Build custom evals, configure tasks
Traces table search bar	AI Search in the filter bar	Natural language to filter syntax
Traces page	Alyx on the main Traces page	Multi-trace analysis, pattern discovery, aggregations, custom metrics, and custom views
Datasets / Experiments	Alyx on Datasets or Experiments	Analyze experiments, manage datasets

Getting started

Open Alyx

Use the keyboard shortcut to open or close the side chat from anywhere in the app.

macOS: Cmd+L
Windows / Linux: Ctrl+L

You can customize this shortcut in Settings. Set any combination of a modifier key (Cmd, Ctrl, Alt, or Shift) and a second key, and Alyx saves it for future sessions in that browser.

Add context to Alyx

Alyx works best when it knows exactly what you’re looking at. There are three ways to give it context:

Highlight: Select any text on the page, such as a span attribute, an error message, or a prompt snippet, then press Cmd+L on macOS or Ctrl+L on Windows and Linux. Alyx opens and adds the selected text to your message. If nothing is selected, the shortcut opens or closes Alyx.
Mention: Type @ in the Alyx input to open a menu. Mention a dataset, experiment, project, or span, and Alyx receives the IDs so it can scope the conversation to that data.
Type it: Include context directly in your message. Reference a trace, dataset, or experiment by ID, or start with “Additional context:” and add what Alyx needs to know.

Whatever you add is sent with your message as input context and displayed as pills in the Alyx input field. Alyx uses this context to scope its response to the data you care about, so you don’t have to restate the situation every time.

Settings

Open Settings from the menu in the top-right corner of the Alyx chat to configure your keyboard shortcut, Auto Accept, and documentation preferences. Additional settings will be added over time. Keyboard shortcut: Change the shortcut used to open and close Alyx, as described in Open Alyx. Auto Accept: By default, Alyx proposes changes as cards that you review and accept before anything is applied. Turn on Auto Accept for a category to let Alyx apply those changes without a confirmation step. Each category is controlled independently:

Eval and task updates: Apply evaluator and task configuration changes automatically.
Annotations: Apply annotation configs and span annotations automatically.
Dataset creation and appends: Create datasets and append rows automatically.
Prompt changes: Apply prompt edits in the playground automatically.

Documentation: Authorize the documentation support skill. When enabled, questions about Arize documentation are answered with help from RunLLM, as described in Third-party integrations.

Chat experience

Edit and resend a message

Hover over a message you have sent and select Edit & resend, or click the message to edit it in place. Change the text and adjust the attached context, then press Enter to send or Escape to cancel. If that message previously produced results, such as a dataset, evaluation, or experiment, Alyx asks you to confirm before resending, because resending rewrites the conversation from that point on. Everything after the edited message is replaced, the turns above it stay in place, and the original turn is archived.

Queue a message

If Alyx is still responding, you can line up your next message instead of waiting. Type it and send, and it appears as Queued beneath the conversation. Alyx sends it automatically once the current response finishes. Send it right away with Send Now, or remove it from the queue.

A single trace tells you something failed. It doesn’t tell you why or how widespread it is. Alyx is grounded in live trace and span context including inputs, outputs, tool calls, errors, and your selected time range, so you can go from noticing a problem to understanding its scope in one conversation.

Setting up an eval means picking a template, mapping variables, and wiring a data source before you’ve even started thinking about what good looks like. Alyx understands your project or experiment and builds the eval for you, and even maps variables in a way that makes sense for your data. It also handles the human side of evaluation, creating annotation configs and annotating spans so reviewer feedback can power your programmatic evals.

Prompt iteration involves more than writing prompts. It means attaching datasets, mapping columns, wiring evals, running experiments, and keeping track of what changed between runs. Alyx holds the full context of your prompt, dataset, evals, and experiment history in one thread so each iteration builds on the last.

Data privacy

Alyx is built on Arize-hosted models (Azure OpenAI and Claude) for their security and compliance features, keeping your data protected and away from third-party providers. Data processing: Azure OpenAI and Anthropic act as data processors for prompts and outputs sent to and generated by Alyx, depending on which Arize-hosted model is used. The models are stateless, meaning no prompts or outputs are stored. No data sharing or model improvement: Your inputs and outputs are not used to improve OpenAI models, any Microsoft or third-party products, Azure OpenAI models, or Anthropic models. Microsoft and Azure OpenAI: The Azure OpenAI Service is fully controlled by Microsoft and hosted in Microsoft’s Azure environment. It does not interact with any other OpenAI-operated services such as ChatGPT or the OpenAI API. Anthropic and Claude: When Alyx uses Claude, Anthropic processes requests on Anthropic infrastructure under Anthropic’s security and data commitments for enterprise API use, separate from unrelated consumer products. Security and compliance: Azure OpenAI and Anthropic help Arize meet industry-standard security and compliance measures throughout the process.

Third-party integrations

Alyx includes a support skill that answers user questions. When you ask a support-related question, that question is sent to RunLLM for processing. Only the specific question you ask is shared with RunLLM. No additional model information or user data is included. You retain control over your interaction with this skill and can revoke consent at any time by contacting support@arize.com. Before using the support skill for the first time you will be asked to acknowledge a one-time disclaimer outlining RunLLM’s involvement.
