Hoping someone can help here. In the documentation the following is provided as a means by which we can simulate optional parameters:
{
"name": "get_weather",
"description": "Fetches the weather in the given location",
"strict": true,
"parameters": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "The location to get the weather for"
},
"unit": {
// highlight-start
"type": ["string", "null"],
// highlight-end
"description": "The unit to return the temperature in",
"enum": ["F", "C"]
}
},
"additionalProperties": false,
"required": [
"location", "unit"
]
}
}
My assumption was that this would mean unit would always be part of the response, but if the model could not identify one that it would return null.
With gpt-4o-mini this approach is sometimes dropping that key altogether in the response.
Does this null approach drop the key or does it guarantee that it will be either F, C, or null?
If the latter, its not functioning as advertised for gpt-4o-mini (streaming function call with Assistants NOT completion in the Playground…)
