Parameter	Type	Default	Range / options
`reasoning_effort` Used to give the model guidance on how many reasoning tokens it should generate before creating a response to the prompt. Low will favor speed and economical token usage, and high will favor more complete reasoning at the cost of more tokens generated and slower responses. The default value is medium, which is a balance between speed and reasoning accuracy.	Select	medium	nonelowmediumhigh
