This release brings a wave of time range improvements, richer project metrics, and finer control over PXI — rolled out across arize-phoenix 17.5.0 through 17.7.0.

​

Calendar Time Range Picker

Available in arize-phoenix 17.5.0+ The time range selector now includes a calendar view for choosing an exact window by clicking dates instead of typing them.

• Two-month range calendar — open the picker to see two months side by side and click a start and end day to define your range
• Editable start and end fields — date fields sit under each month so you can fine-tune the bounds, including the time of day, before applying
• Apply or cancel — the range only commits when you apply it, so you can explore dates without disturbing the current view

​

Pan, Zoom, and Live Streaming Controls

Available in arize-phoenix 17.6.0+ A compact control strip now sits beside the time range selector on the project and dashboards pages, replacing the standalone streaming switch.

• Pan and zoom — step the window backward and forward or widen and narrow it without reopening the selector; large zoomed-out windows snap to readable units (for example 85d instead of 2048h)
• Live streaming toggle — a play/pause control on the project page turns live data streaming on and off, with a gentle pulse while streaming is active
• Shared chrome — the strip matches the height and styling of the time range selector so the two read as one control

​

Shareable Trace Time Range URLs

Available in arize-phoenix 17.7.0+ Trace and session views now encode the time range in the URL, so a link you copy reproduces what you were looking at for the recipient.

• Time range in the link — the active range travels with the URL, whether it’s a named preset or an explicit start and end window
• Presets stay relative — sharing a preset link (such as the last hour) resolves to the recipient’s current window, while a custom range shares the exact bounds you selected
• Cleaner navigation — selection state stays in the URL across tab changes, so refreshing or sharing a trace view keeps the same context

​

Trace and Session Annotation Scores Over Time

Available in arize-phoenix 17.6.0+ The project metrics page now charts average annotation scores at the trace and session level, alongside the existing span annotation scores.

• Trace annotation scores — a panel plots average trace annotation scores over the selected time range
• Session annotation scores — a matching panel tracks session-level annotation scores
• Consistent visualization — span, trace, and session annotation panels share the same chart, so scores across all three levels read the same way

​

Token Detail Metrics Charts

Available in arize-phoenix 17.7.0+ The project metrics page adds two charts that break token usage down into its component parts over time, complementing the existing token usage panel.

• Prompt token details — see prompt tokens split across input, cache, and audio parts
• Completion token details — see completion tokens split across output, reasoning, and audio parts
• Time-aligned — both charts follow the page’s selected time range, so you can correlate token detail trends with cost and volume

​

PXI Subagents Are Now Opt-In

Available in arize-phoenix 17.5.0+ (PXI beta) PXI subagents — the parallel helpers that run read-only data lookups alongside the main investigation — are now controlled by a toggle in assistant settings and default to off.

• Subagents toggle — find it directly below the Web Search toggle in your personal assistant settings
• Off by default — PXI runs without subagents until you enable the toggle, so you opt in to the additional token usage they can incur
• Same behavior once enabled — turning subagents on restores the parallel data-retrieval flow introduced in the June 10 PXI update
