Models which support file_search

Hi all,

I am using openai assistant to search files but the model used in example code is costly. I am trying to find a cheaper one than gpt-4o. Is there a list of models which support file_search?

assistant = client.beta.assistants.create(
model=“gpt-4o”,
tools=[{“type”: “file_search”}]
)

The gpt-3.5-turbo also supports the file_search functionality so it could be a budget-friendly alternative to gpt-4.
