Questions about xAI rates
Do these xAI figures include discounts and tax?
No. They are public list rates. Commits, credits, regions, tax, and commercial discounts are not in the number — check the source linked on each model.
When is the more expensive xAI tier worth the extra?
Grok 4.6 sits near $3.20 per 1M tokens on a 70/30 mix, versus $1.30 on Grok Build 0.1. Use the high tier when retries or long reasoning actually fail on the cheap one.
