Reasoning tokens are billed as part of total consumption
Be aware that tokens used for Grok model reasoning are included in your overall usage costs.
Factor in the cost of reasoning tokens when estimating API usage for Grok models.
Savings
Optimize reasoning_effort settings to balance performance and cost.
How
Monitor your API usage reports to track consumption related to reasoning processes.
What it does and when to use it
When using Grok models, the tokens consumed by the model's internal reasoning processes are counted towards your total API usage and billing. This means more complex reasoning tasks will incur higher costs.
