Analyze Cost and Usage

This page assumes traffic through at least one LLM provider; with no traffic, the charts are empty.

Open Cost and usage in the sidebar. The page has two tabs:

The date-range picker offers last 24 hours, last 7 days (the default), last 14 days, last 30 days, last 90 days, month to date, quarter to date, year to date, and custom ranges. The chart subtitle shows the selected date range and bucket size.

When you open the report without a range in the URL, it starts on the default and widens on its own until it finds your most recent spend, one rolling preset at a time, up to last 90 days. The picker always names the range actually in use. Choosing a range yourself, including a custom one, stops the widening for the rest of the visit, and the automatic steps don’t build up browser history. The Activity tab widens its own window the same way.

A custom range sets an exact start and end time, to the minute and interpreted in UTC, rather than a relative period. It writes customStart and customEnd ISO-8601 timestamps to the page URL, so the view is shareable: copy the URL after picking a custom range and any teammate who opens it lands on the same window.

To compare against the period before, turn on the Compare to previous period switch in the date-range picker. The picker shows which previous window the report compares against, and each series in the report compares against its own numbers from that period. While a comparison is on, the picker’s button carries a vs prev badge, and the comparison is recorded in the page URL, so a compared view is as shareable as a custom range.

Hover over a bucket in any chart to read each series' value in that bucket. While a comparison is on, the detail also shows each series' value in the previous period and the change between them, as both an amount and a percentage. A series with no traffic in the previous period reads as (new) rather than a percentage.

Use Group by to switch the chart breakdown between providers, models, token type, agents, users, and tags:

Each dimension, Provider, Model, Cost type, Token type, User, and Agent, has its own filter button above the charts, and you can combine them freely. For example, filter to one Anthropic provider, drill into claude-opus-4-7, then limit the spend view to input tokens. Selecting an agent also narrows the provider options to the providers that agent used. The tag filter is independent of grouping, so you can group by model while filtering to env=prod.

Deleted providers stay in the report so history remains complete. Turn off Show deleted providers to hide them; when everything that matches your filters is from deleted providers, the chart says so instead of rendering blank.

The report includes these charts:

The chart renders empty buckets in the selected range as zero-height bars rather than gaps, so quiet days line up with their date label and the trend stays readable when traffic is bursty.

The charts share the bucket you’re pointing at. Hovering a bucket in one chart highlights the same time bucket in the other two and shows each one’s detail for it, so spend, requests, and tokens read against the same point in time without hovering each chart in turn.

The chart palette is colorblind-safe. When multiple providers of the same type exist (for example, two OpenAI providers), the chart renders each one with a distinct hatched pattern so the series stay visually distinguishable.

The spend chart footer summarizes the selected view by cost bucket, including total, input, output, cached, cache writes, and reasoning when the selected traffic includes those categories.

Each chart’s legend is interactive. Select a series to hide it, and select it again to bring it back. A hidden series stays in the legend with its label struck through, and the last visible series can’t be hidden, so a chart never empties. Hiding is per chart and per visit. It isn’t recorded in the page URL.

Select a bar to narrow the whole report to the series that bar belongs to. The series' value becomes a page filter on its own dimension, whether that’s a provider, a model, an agent, a user, a cost type, a token type, or a tag value. The result is the same as setting that filter by hand, so the filter buttons show what the drill-down applied, and you clear it there.

When the chart groups by agent, each agent in the legend also has a View activity button. It opens the Activity tab for that agent over the window the chart is showing.

Each chart can be maximized for a closer look, and exported on its own: the chart export downloads the data as currently shown, including any truncation the chart applies to keep the top series readable. The legend, the drill-down, and View activity work the same way in the maximized view.

To export the data behind the charts, use the download controls in the toolbar:

Use Download full report when you need the whole dataset rather than the charted view.

The Activity tab answers a different question from the report: instead of what something cost, it shows what’s running right now. It ranks the agents with traffic over a window of the last hour (the default), the last 24 hours, or the last 7 days, and shows each agent’s change against the previous window. Select an agent to see its recent requests and open a conversation.
