returnThinking

public OpenAiChatModel.OpenAiChatModelBuilder returnThinking(Boolean returnThinking)

This setting is intended for DeepSeek.

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 reasoning_content 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.
