OpenAI JSON Mode

Could anyone guide me with using the new JSON mode Openai has introduced? Should the code be formated like this? The documentation isnt too clear.

{

"model": "gpt-3.5-turbo-1106",

"messages": [

{

"role": "user",

"content": "What is the weather like in Boston? Respond in JSON"

}

],

"response_format": "json_object"

}
