This page describes how to manage your conversations with ARIA: starting and resuming chats, queueing follow-up messages, adding context, granting network access, and giving feedback on responses. Context can include runs, workspace panels, W&B Weave traces, and images. It also covers organizing your chat history by renaming, pinning, and deleting conversations.

​
Start a new chat

To start a new chat, open ARIA, then click the pencil icon in the upper right corner of the chat window. You can run multiple chats in parallel at a time. ARIA notifies you when it responds to a chat, even if you have closed the chat window. Starting a new chat does not delete your previous conversations. To view previous conversations, click (Reveal chat history) to open the chat history sidebar.

​
Send a message

Type a message and press Enter to send it.
  • Press Shift+Enter to add new lines.
  • Click + to add images.
  • To add a run reference, type @ and select a run from the list. Type to filter and fuzzy-search the list.
  • For more flexibility, compose a more complex message in a text editor and paste it. Plain text is supported, and pasted @ characters are not resolved to run references.
To cancel the current operation and immediately send the next queued message, press the stop icon to the right of the text input. To help you stay in context, ARIA renders line plots, bar charts, and scatter plots directly in the chat, with support for full-screen view. Hovering over a run in the runs list on the Workspace or Runs tab highlights the run’s plots in ARIA, and hovering over a panel in ARIA highlights the run in the runs list on the Workspace tab.

A scatter plot shows one point per run and plots two of each run’s config or summary values against each other, such as a hyperparameter against a final metric. For example:
User prompt
Each point uses a run’s single config or summary value, not its logged history. An axis can also show when each run was created or last sent a heartbeat. To show a metric over steps, ask for a line plot instead. You can ask ARIA to set axis labels, ranges, and logarithmic scales, and to add a linear regression line. A scatter plot includes up to the first 500 visible runs. To narrow it, filter the runs, hide some runs, or ask ARIA to filter or hide runs for you or tell it which runs you are interested in. Hover over a point to see its run and values.

To change a chart, ask ARIA to redraw it. Charts in the chat are read-only.

​
Queue messages

The message queue holds follow-up tasks and questions you send to ARIA while it works. ARIA runs each queued message in order using the full conversation as context. The next message runs as soon as the previous one finishes. Use the queue to line up several steps at once and step away, rather than returning to the chat to send each one. For example, you might start with a comparison: While ARIA works, send additional requests to the chat window. W&B adds pending requests to ARIA’s queue. This example sends two messages at once:
Queued messages
The queue header shows how many messages are waiting. Each queued message has three controls:
  • Pencil icon (): Edit the message before ARIA runs it. ARIA moves the message into the message box and removes it from the queue, so send it again to requeue it. This control is unavailable while the message box already holds a draft.
  • Up arrow icon (): Run the message now instead of waiting its turn. ARIA stops what it’s working on and runs this message next. The other queued messages keep their order.
  • Trash can icon (): Delete the message from the queue.
Queued messages keep the context you attached to them, including run mentions and images. Queueing begins after your first message in a chat, because a queue needs a conversation to run against. The first message you send, and any message you send to an idle chat with an empty queue, goes to ARIA immediately. Each chat keeps its own queue, and the queues in chats you close keep running. If ARIA needs a clarifying answer or your permission before it continues, the queue pauses until you respond. To run a queued message without responding first, click the up arrow icon next to it.

​
Jump to an earlier message

In a long conversation, use the turn rail to return to an earlier message without scrolling. After you send your second message in a conversation, the rail appears along the right edge of the chat window. The rail has one mark for each message you sent.

Use the rail to preview, jump to, and track your messages:
  • Preview a message: Move the pointer along the rail. The marks near the pointer widen, and a card shows the start of your message and a preview of ARIA’s response.
  • Jump to a message: Click a mark. The chat scrolls until your message is at the top of the chat window.
  • See where you are: The mark for the message at the top of the chat window stays highlighted as you scroll.
To use the keyboard, press Tab to move focus to a mark and show its preview card. Then press Enter to jump to its message.

​
Manage conversations

The following sections describe how to view, rename, pin, and delete your conversations.

​
View chat history

To view previous conversations:
  1. Open ARIA.
  2. Click (Reveal chat history) to open the chat history sidebar. It’s collapsed by default. The same control reads Collapse chat history while the sidebar is open.
  3. Select a conversation to resume it.
Pinned conversations appear first, under a single Pinned header, not grouped by date. Unpinned conversations follow, grouped Today, Yesterday, Last 7 Days, Last 30 Days, then by month, then by month and year for conversations older than a year. Within each group, the most recently active conversation appears first. Hover over a conversation row, or focus it with the keyboard, to reveal two controls: The chat history sidebar’s Customize section also lists the ARIA automations you’ve created. See Use automations with ARIA.

​
Rename a conversation

When you send the first message in a new chat, ARIA generates a title for the conversation. The title shimmers in the chat history sidebar while ARIA writes it. If ARIA can’t generate a title, the conversation keeps an excerpt of your first prompt as its title. ARIA titles a conversation only once. Follow-up messages don’t change the title. To give a conversation a different title:
  1. In the chat history sidebar, hover over the conversation you want to rename.
  2. Click (Chat actions), then select Rename chat. The title becomes an editable field.
  3. Type a title, up to 255 characters.
  4. Press Enter or click (Save chat title) to save. Press Escape or click (Cancel rename) to discard your change.
Clearing the field and saving replaces the title with an excerpt of your first prompt, or Untitled conversation if no excerpt exists. Saving whitespace-only input cancels the rename instead of clearing the title. Renamed titles sync across your open browser tabs. You can also rename a chat from your phone. See Chat with ARIA in the mobile app docs.

​
Pin a conversation

Pin a conversation to keep it at the top of the chat history sidebar instead of letting it slide down as new chats accumulate.
  1. In the chat history sidebar, hover over the conversation you want to pin.
  2. Click (Pin chat). The conversation moves under the Pinned header.
  3. To unpin, click (Unpin chat) on a pinned conversation.
There’s no limit on how many conversations you can pin, and pin changes sync across your open browser tabs. Pinning affects only your own conversation list, not what teammates with access to the same project see.

​
Delete previous conversations

To delete a previous conversation:
  1. Open ARIA.
  2. Click (Reveal chat history) to open the chat history sidebar.
  3. Hover over the conversation you want to delete, click (Chat actions), then select Delete chat.
  4. In the Delete this chat? dialog, click Delete to confirm. You can’t undo this action.

​
Undock chat window

You can undock the chat window into a separate window, which allows you to view ARIA’s response side-by-side with your project data. To undock the chat, click the undock icon in the upper right corner of the chat window next to the close (X) button.

​
Add context to a conversation

Attach runs, workspace panels, and Weave traces and evaluations to a chat to give ARIA the exact context for your question. Each item appears in the message box as a removable tag. You can attach several items to a message. Adding context doesn’t send the message on its own. When you’re ready, click Send. When you add context from a page, ARIA adds it to the conversation that’s open in the chat window. If no conversation is open, ARIA starts a new one.

​
Mention a run

Type @ in the message box and select a run. For example, you can ask ARIA to analyze a specific run by including the run’s name in your prompt:
User prompt
You can also add a run from the runs list on the Workspace or Runs tab. Hover over the run, click its action () menu, then select Ask ARIA.

​
Add a workspace panel

To attach a workspace panel to a chat:
  1. In your workspace, hover over the panel and click its action () menu.
  2. Select Ask ARIA. ARIA opens with the panel attached.
  3. Type your question, such as Why does loss spike after step 2,000?, then send it.
Ask ARIA appears in panel menus in workspaces you can edit. It doesn’t appear in panels in reports.

​
Add Weave traces and evaluations

In Weave, click the ARIA button to attach traces, evaluations, or evaluation results to a chat. Hover over the button to see its label, such as Ask ARIA about this trace or Ask ARIA about these evals. The button appears in these places:
  • Traces or Evals table: Select one or more rows. The button appears in the table toolbar and attaches every selected row.
  • Trace or evaluation details page: The button appears in the page header.
  • Evaluation comparison: When you compare evaluations and view an example’s details, the button attaches the predictions and scores for that example.
ARIA uses the attached traces and evaluations to answer your question. For example:
User prompt

​
Add an image to a conversation

Click the plus icon (+) in the lower left corner of the chat window to add an image to your conversation. You can then ask ARIA to analyze the image or provide information about it.

​
Grant network access

When a task needs a domain that ARIA’s sandbox blocks, ARIA asks you for network access and waits for your answer. For example, a task that installs a Python package needs pypi.org and files.pythonhosted.org. By default, the sandbox where ARIA runs code can reach W&B services but blocks most other domains on the internet. The request appears in the chat under The agent is requesting network access. It shows the reason for the request and lists the requested domains, all selected. Respond to the request in one of these ways:
  • To grant access, clear any domains you don’t want to allow, then click Grant access. ARIA continues its work and can reach the granted domains.
  • To deny access, click Deny. ARIA continues without the extra access.
While a request is waiting, you can’t send messages, and queued messages don’t run.
Code that runs in the sandbox can send data to any domain you grant. Grant access only to domains you trust.
Granted domains stay available for the rest of the conversation until you revoke them. Each new chat starts with only the default access. You can’t add domains yourself. ARIA requests them when a task needs them.

​
Review or revoke network access

After you grant access in a conversation, (Manage network access) appears in the message box, next to the plus icon (+). To revoke access:
  1. Click (Manage network access). A list of the conversation’s granted domains opens.
  2. Clear the domains you want to revoke.
  3. Click Update access.
W&B sends ARIA a message listing the revoked domains, and ARIA runs without them from then on. You can’t change network access while ARIA is working.

​
Provide feedback

Click the thumbs up or thumbs down icon at the end of the response to provide feedback on ARIA’s response. Your feedback helps W&B improve ARIA’s performance and accuracy. For information about how W&B handles data usage for ARIA, see Governance and security.
