I am trying to understand if the VAP API can be used in the same way as the OpenAI's realtime API? Can I just create the assistant on the fly dynamically?

yes, you can use transient assistants

Hey Emma, You can absolutely assistants on the fly as Bryant mentioned previously. Our term for them is "Transient Assistants", which are temporary assistant configurations passed directly in the request payload. Here is a community tutorial surrounding the topic: If you run into any problems feel free to reach out, we're here to help!

when you use the create call method with the API, instead of passing the assistantID parameter you'll pass the assistant object with all the options you want for your assistant inside it. check out the playground on the API documentation
