Parameters

Model options, passed in modelOverride.config.

Parameter	Type	Default	Range / options
`reasoning` When enabled, the model uses adaptive thinking to dynamically decide when and how much to think before responding. Adaptive thinking is on by default in Claude Sonnet 5.	Select	true
`effort` Controls how much the model thinks vs. how quickly it responds. Higher effort produces better quality but uses more tokens and is slower. Recommended: High for coding and agentic work; Medium for general use; Low for short, latency-sensitive tasks. Only applies when Reasoning is enabled.	Select	medium	lowmediumhigh
`tools`	Tools	—	—
