Week of Sep 28, latest, median of 2 providerslog axis

Median tokens per second once generation starts, measured on traffic routed through Requesty through Oct 2. Hover a week to read it.more

The axis is logarithmic, because the lines here are more than 12x apart and a linear axis would press most of them flat. Each gridline is a step in ratio rather than a fixed amount. The axis is set by the bulk of the weeks, not by the extremes, so 2 weekly points sit off the frame and are marked with a caret at the edge: hover one for its figure. Stretching the axis to reach them would flatten every line worth comparing. The bold line starts in the week of Aug 3, the first week this model was called through Requesty, and the weeks shaded before it hold no sample for it. Each provider line is that provider's own median across every model it serves, which is the grain published per provider, so a provider line can cover weeks this model was not called in yet. The exact per-provider figures for this model are ranked below.

The two panes rank gemini-2.5-flash as measured on Requesty traffic: by the provider that served it, and by the region the request came from, where the share is how much of that region's traffic this model carries. Whole-window figures, because that is the grain Requesty publishes per provider and per region.

Whole-window figures as published, not an average of weekly points. Measured over streaming responses only, because a non streaming request has no first token event. A reasoning model thinks before it emits anything, so compare its wait against its reasoning share rather than against a non reasoning model.
