Model pricing
Grok 4.5 API list price — cost per token
Grok 4.5 costs $2.00 per million input tokens and $6.00 per million output tokens (USD). Requests with ≥200K tokens in the prompt, including cache reads and writes, use the premium rates for the whole request. Official rates are published at docs.x.ai/developers/pricing. On Grok Build (SuperGrok / X Premium+) this is a notional list-price figure, not subscription spend.
