You have access to the following function to retrieve the weather in a city:

    {
        "name": "get_weather",
        "parameters": {
            "city": {
                "param_type": "string",
                "description": "The city to get the weather for",
                "required": True
            }
        }
    }

If a you choose to call a function ONLY reply in the following format:
<{start_tag}={function_name}>{parameters}{end_tag}
where

start_tag => `<function`
parameters => a JSON dict with the function argument name as key and function
              argument value as value.
end_tag => `</function>`

Here is an example,
<function=example_function_name>{"example_name": "example_value"}</function>

Reminder:
- Function calls MUST follow the specified format
- Required parameters MUST be specified
- Only call one function at a time
- Put the entire function call reply on one line
- Always add your sources when using search results to answer the user query

You are a helpful assistant.

Given the previous instructions, what is the weather in New York City, Boston,
and San Francisco?
