Latest Snapshots

“Most recent” is defined as the evaluation in the group with the latest created_at timestamp — not the order in which evaluations were added to the group.

When to use it

Snapshot tiles at the top of a dashboard that need to read the last run’s score.

Comparison views where you want the latest run highlighted alongside trend visualizations of the full group.

Always-fresh KPI widgets that should automatically refocus on a new evaluation as soon as it’s added to the group.

Where it applies

Latest snapshots are only available on widgets that issue a query.

Widget type	Latest Only available?
Metric (Query Value)	Yes
Bar	Yes
Histogram	Yes
Donut	Yes
Table (grouped or flat)	Yes
Scatter	Yes
Timeseries	Yes, but rarely useful — collapses the chart to a single point
Markdown, Heading	Not applicable

The toggle is only available on evaluation group dashboards.

Enable via the SDK

Set latest_only: true on the query payload when creating or updating the widget. The flag is supported on both SeriesQuery (Bar / Histogram / Donut / Table / Scatter / Timeseries) and MetricQuery (Metric / Query Value).

# Metric widget that always shows the average score of the most recent run in the group
client.evaluation_dashboards.widgets.create(
    dashboard_id=dashboard.id,
    title="Latest Snapshot: Average Score",
    type="metric",
    query={
        "select": [
            {
                "expression": {
                    "type": "AGGREGATION",
                    "function": "AVG",
                    "column": "overall_score",
                    "source": "data",
                },
            }
        ],
        "latest_only": True,
    },
)

Omitting latest_only or setting it to false keeps the existing behavior of computing across the full group.
