[tydinj]

How do I add attachments to a message? Trying to support this https://platform.openai.com/docs/assistants/tools/file-search

You can either add Tool.FileSearch to your list of tools:

var tools = new List<Tool>
{
    Tool.FileSearch, // or
    new Tool(new FileSearchOptions(20))
};

then do something like this:

message = await thread.CreateMessageAsync(new(
    content: "Test create message",
    attachments: new[] { new Attachment(file.Id, Tool.FileSearch) }
));
