Artificial Analysis makes Time per Task its headline API speed metric
Overview
Artificial Analysis says it now uses Time per Task as the headline metric for comparing model speed across roughly 1,000 serverless API endpoints.
The metric divides output tokens per Intelligence Index task by end-to-end output speed, so it measures how long a model takes to finish a task rather than how fast it streams tokens.
The source says default API effort settings cut Time per Task by about 3 to 5 times for GPT-6 Astra, GPT-6.1 Sol and Claude Opus 5.5, with lower Intelligence Index scores.

The metric divides output tokens per Intelligence Index task by end-to-end output speed, which counts the full request from send to final token.
