Seeds & JSON Response Format for Assistant API

Hi there,

From my understanding these features are only available for the completions endpoint but can someone say if these features can also be used with the assistant API?

Json probably not available yet, as the only setting you can give to Assistant about the model is its name, but to use this mode you need another parameter passed:
"response_format": { "type": "json_object" },
