How do I configure temperature and other hyperparameters when creating an assistant using the OpenAI API?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm using the following code to create an assistant:

PYTHON
assistant = client.beta.assistants.create(
  instructions="""<Instructions>
 """,
  model="gpt-4-1106-preview",
  tools=[{"type": "retrieval"}],
  file_ids=[file.id]
)

I assume there's an argument to specify model hyperparameters such as temperature and top_p in this API call, but I haven't found one. Is there a parameter or another method to set these options?

You can set hyperparameters like temperature and top_p directly via optional parameters in the request body. For example, you can pass them as follows:

PYTHON
assistant = client.beta.assistants.create(
  instructions="<Instructions>",
  model="gpt-4-1106-preview",
  tools=[{"type": "retrieval"}],
  file_ids=[file.id],
  temperature=0.7,  # Adjust sampling temperature
  top_p=0.9         # Adjust nucleus sampling
)

According to the documentation, these parameters allow you to modify the randomness and diversity of the output. No additional argument is required—just include these optional fields in your API call.
