Availability

24 hours · 10/29–11/02

Success rate of requests sent by the Amux AI gateway to each provider. Client errors are excluded.

Tok/s

24 hours · 10/29–11/02

Average output speed of streaming requests, in tokens per second (TPS).

TTFT

24 hours · 10/29–11/02

Average time to first token (TTFT) of streaming requests, measured from request dispatch to the first token received.

Activity

24 hours · 10/29–11/02

Relative request activity over time, broken down by serving provider. Indexed to the peak within the selected range (= 100); reflects trends and provider share, not absolute volume.
