Bug Report: “This model doesn’t support file attachments” message
`Steps to Reproduce`
I’ve been using one model, o3-mini-high, for the entire duration of a chat. The first message in the chat had an image. After a long period of chatting and switching to 4o and immediately trying to switch back I get this message “ this model doesn’t support file attachments”. Keep in mind I never submitted any request with 4o enabled.
`Expected Result`
The user is able to switch back to the model that they originally selected and have been using for the duration of the chat.
`Actual Result`
Switching to 40 and back to o3-mini results in the error message “this model does not support attachments”
`Environment`
All
