model-router

Configuration

The thinking model is a model-router settings namespace (persisted in settings.yaml):

Field	Meaning	Default
thinkingProvider	Provider route for step-1 requests	deepseek-official
thinkingModel	Model id for step-1 requests	deepseek-v4-pro
reasoningEffort	Adapter-owned reasoning effort (off / high / max, empty = provider default)	high

Ways to change it:

• UI — the 🧠 pill in the composer: model dropdown (grouped by provider, from the live catalog) + reasoning-effort dropdown; selection applies immediately.
• Settings — the namespace may also appear in the Settings → Plugins section (schema-driven card), depending on the deployment's settings UI.
• Settings file — edit settings.yaml:

model-router:
  thinkingProvider: deepseek-official
  thinkingModel: deepseek-v4-pro
  reasoningEffort: max

• Composition — change the row config: (the base layer; user settings win over it).

The execution model is not configured here: it always follows the agent's default model selection (the Web model selector / agent-default-model settings). To make execution fast, set the default model to a cheap model such as deepseek-v4-flash.
