Determines the tool calling behavior of the model.
When set to none, the model will bypass tool execution and generate a response directly.
In auto mode (the default), the model dynamically decides whether to call a tool or respond with a message.
Alternatively, setting required ensures that the model invokes at least one tool before responding to the user.
You can also specify a particular tool by {"type": "function", "function": {"name": "my_function"}}.
