+<Tip>
+  The V4 series (`deepseek-v4-pro`, `deepseek-v4-flash`) supports thinking mode together with tool calls, enabling multi-round reasoning + tool orchestration in Agent mode. The thinking switch is controlled by the global `enable_thinking` setting, and `reasoning_content` is automatically round-tripped on tool-call turns.
