Reasoning-token prices
Some vendors list a rate for reasoning tokens apart from the output rate. This table is that listed rate. It does not estimate how many reasoning tokens a task will use, and it is not a tax added on top of a workload. Reasoning effort is the page for thinking that cannot be turned off.
