Usage > Cross platform charts your LLM spend month over month. Use it to spot spending trends and to break a single month down by provider. Each bar in the monthly chart represents one month’s total estimated spend. Cross platform appears under Usage for organization admins and for the owner of a personal account.

​
Drill into a month

Select a month to focus the chart on it. You have two ways to select:
  • Click the month’s bar in the chart.
  • Choose the month from the Month picker in the chart header.
Selecting a month highlights its bar and dims the other months. Clear the selection to return the chart to its resting state.
The chart announces the selected month through a live region, and the Month picker supports keyboard and touch selection, so the drill-down works with a screen reader.

​
Month-detail band

A fixed-height detail band sits below the monthly chart. Its contents change with your selection.

​
Resting month-over-month table

When no month is selected, the band shows a table of every month. Each row lists the month with leader dots, the month-over-month (MoM) percentage change against the prior month, and a marker on months whose spend is estimated.

​
Selected-month provider split

When you select a month, the same grid shows that month’s spend split across providers, such as Anthropic and OpenAI.

​
Date-range stepper

Each chart and breakdown card names the window its numbers cover in a pill in its header. On this page that pill is also the control: use its arrows to move the window through time without reopening the Time Window filter.
  • The Back arrow shifts the window earlier by its own length, so a Jul 20 – Aug 18 window steps back to Jun 20 – Jul 19. Adjacent windows tile with no overlap and no skipped days.
  • The Forward arrow shifts it later by the same length, and is disabled once the next window would run past today. Windows are UTC calendar days, so the limit is today in UTC rather than in your own timezone.
  • Stepping forward onto a preset’s own window restores that preset rather than leaving the page on a custom range covering the same days.
The same pill and stepper arrows appear on Usage > Overview.

​
Six-month outlook badge

The chart header displays a six-month outlook badge with your projected spend for the next six months, fitted from a linear regression of your account’s total spend over the last eight complete weeks. The projection covers a single total rather than a per-platform split, and includes an 80% confidence range from a low to a high estimate. Hover or focus the badge to open a tooltip that explains what the outlook represents.
