Output is billed at a multiple of input on most models. The Out/In column is that multiple — it matters more than the input price once output dominates your bill.

Across 32 billable models the rate spans $0.1 (grok-4-1-fast-non-reasoning) to $2.5 (grok-2-vision-1212) per million input tokens — a 25× spread. Picking the wrong tier is usually the single most expensive mistake here.

What xAI is good at

Grok is competitive on real-time and search-adjacent workloads.

Before you compare: Grok rates are shown at gateway price. Official xAI list pricing is not published in a stable machine-readable form, so no discount is claimed.
