Parameters

Model options, passed in modelOverride.config.

Parameter	Type	Default	Range / options
`reasoning` When enabled, the model uses adaptive thinking to decide when and how much to think before responding. Adaptive thinking is on by default. Turning it off skips the up-front thinking.	Select	true	truefalse
`effort` Controls thinking depth, latency, and cost. The default is High. Higher effort improves quality but uses more tokens and is slower. Recommended: High for general use, Medium for well-specified agentic work, Low for short latency-sensitive tasks, Extra High or Max for the hardest tasks. Only applies when Reasoning is enabled.
