!code used to work via search, now it brings me to the assistant page, but my entire prompt gets clobbered and the page is blank, but it does create a new thread. If I then attempt anything in the thread (such as "hi"), it results in an error Model Claude 4.6 Sonnet requires Unlimited plan. I have an older thread from a day or 2 ago that does nothave this issue, but all new threads do. My usage is at $2.51/108.00 so I don't think that's it.
I'm also seeing the call to the session's /context is returning
{"error":{"code":"bad_request","message":"Unknown model: assistant:code","request_id":"06dee2c9-df55-491f-b353-07423cf87b28","fields":[]}}
!code starts a functioning session just like it used to
