Output speed on xAI
Output tokens per second for the 6 of 7 models on xAI with published throughput telemetry, the most recent figure OpenRouter publishes for each host. The full table below lists all 7, measured or not. Higher is better. We do not run these measurements ourselves.

The Known Good
Source. Prices, endpoint availability and throughput for xAI are ingested from OpenRouter;
model metadata is enriched from models.dev. A blank cell means the figure was not published for that endpoint —
it never means zero. Blended price is (3 × input + output) ÷ 4, the same 3:1 blend used everywhere on this
site; see methodology. Quality scores are not provider-specific:
a model scores the same wherever it is hosted, so quality lives on the
model pages.
