ThinkingConfig

ThinkingConfig = { effort?: ThinkingLevel; type: "adaptive"; } | { budgetOverrides?: ThinkingBudgets; effort: ThinkingLevel; type?: undefined; }

Defined in: src/config.ts:21

Configuration for reasoning/thinking.

• Effort-based (cross-provider): Set an effort level, mapped to each provider’s native format by pi-ai’s streamSimple() (e.g., reasoning.effort for OpenAI, thinking for Anthropic/Google).
• Adaptive (Anthropic 4.6 only): Model decides when/how much to think. Uses pi-ai’s stream() with thinkingEnabled.
