IQ vs Speed

Each model's estimated IQ against its completion time, which is time to last token (TTLT). Drag the input (1K–10K tokens) and output (100–10K tokens) sliders to see how it changes with the workload.

Completion time by task shape

Completion time is time to last token (TTLT). It combines time to first answer token with the time required to stream the requested output length.

Use the input and output sliders to compare short prompts, long-context prompts, brief answers, and long generations using the same underlying response-time model as the chart gallery.

Iso-curves trace equal preference for IQ versus speed. Models farther up and to the left are better: higher estimated IQ with lower total response time.
