CostDistribution

Price distribution shows typical request cost

Quartiles reveal what most runs cost; spikes usually mean long prompts or outputs

  • Median = typical cost per 100 requests for this model
  • Wide spread means costs vary a lot by prompt size or tools
  • Use this to estimate pricing before scaling usage

Price Distribution

Typical price per 100 requests across recent runs

SpeedDistribution

TTFT distribution shows how fast responses start

Lower time-to-first-token means snappier experiences

  • Median TTFT = typical wait before tokens start
  • Wide spread means response speed varies by prompt complexity
  • Aim for lower TTFT on interactive user flows
