Enables thinking.

thinkingBudgetTokens

public AnthropicStreamingChatModel.AnthropicStreamingChatModelBuilder thinkingBudgetTokens(Integer thinkingBudgetTokens)

Configures thinking.

returnThinking

public AnthropicStreamingChatModel.AnthropicStreamingChatModelBuilder returnThinking(Boolean returnThinking)

Controls whether to return thinking/reasoning text (if available) inside AiMessage.thinking() and whether to invoke the StreamingChatResponseHandler.onPartialThinking(PartialThinking) callback. 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().

• thinkingType(String)
• thinkingBudgetTokens(Integer)
• sendThinking(Boolean)

sendThinking

public AnthropicStreamingChatModel.AnthropicStreamingChatModelBuilder sendThinking(Boolean sendThinking)

Controls whether to send thinking/reasoning text to the LLM in follow-up requests.

Enabled by default. If enabled, the contents of AiMessage.thinking() will be sent in the API request. If enabled, thinking signatures (inside the AiMessage.attributes()) will also be sent.
