returnThinking

public AnthropicChatModel.AnthropicChatModelBuilder returnThinking(Boolean returnThinking)

Controls whether to return thinking/reasoning text (if available) inside AiMessage.thinking(). Please note that this does not enable thinking/reasoning for the LLM; it only controls whether to parse the thinking field from the API response and return it inside the AiMessage.

Disabled by default. If enabled, the thinking text will be stored within the AiMessage and may be persisted. If enabled, thinking signatures will also be stored and returned inside the AiMessage.attributes().
