Reasoning terminology
Poolside and compatible providers use related terms for model reasoning behavior:- Reasoning: The general model capability or behavior. In API contexts, this can also refer to fields such as OpenRouter’s
reasoningobject or assistantreasoning_content. - Thinking: The Poolside term for turning reasoning behavior on or off per request.
- Effort: A generic scale used to express how much reasoning to request. ACP clients support
default,max,xhigh,high,medium,low,minimal, andnone; OpenRouterreasoning.effortvalues depend on provider model metadata. - Thought level: The ACP session config option that maps to effort values.
Access models
How you access Poolside models determines which API base URL, reasoning controls, and model IDs are available. To find model IDs for your access method, see List available models.
