Above 272K input tokens, the full request costs 2x input/cache and 1.5x output. Batch/Flex cost 50% of Standard; Fast costs 2x; regional processing adds 10% where available. Reasoning output tokens are charged at output rates. | SpaceXAI xAI API global standard tier, USD per million tokens. Below 200,000 prompt tokens: $2 input, $0.50 cached input, $6 output. Above 200,000 prompt tokens: $4 input, $1 cached input, $12 output. Fast serving and regional endpoints have separate conditions. The provider explicitly states there is no text output limit; no numeric maxOutputTokens is asserted. |
