Failed to generate nested AI content…

I keep getting this message in the Aiomatic activity log: "Failed to generate nested AI content: Error in AI: Failed to query assistant: HTTP request failed with code (assistant id: ' . gpt-3.5-turbo-instruct . ') 404:" I have been using Aiomatic for months with Newsomatic to rewrite incoming post titles and the post content. It has worked flawlessly until a few days ago. Now, the [aicontent]%%item_title%%[/aicontent] for the title and [aicontent]%%item_content%%[/aicontent] for the post body are both blank. That has never happened before. Any ideas about what I can do to get this working again. I notice there have been a lot of Aiomatic updates lately. Also, are you recommending gpt-3.5-turbo-1106 now? I am not using images through Aiomatic, only text for now. Thanks, LarryT.
