Missed the update, and noticed my posts were failing since May 6th. Whoops.

I changed the model to GPT4-1, and they're working again, but is GPT-5x supposed to be OK now? So far, that has not been working for me (tested today).

In this case, we need to know exactly which model you are using (GPT-5.1 and GPT-5.5 behave differently), as well as what error message it is returning.

Please provide your Syndicator log for analysis.

I can only use GPT-5.1 in the version I have. To be clear, are those versions currently working on your side?

Things are working again under GPT4-1, but I could switch to GPT-5.1 again. Looking at the log before, it simply stated 'Unknown OpenAI error.'

There were no other meaningful details before or after that, but if necessary, I can provide them.

Of course, the plugin works with all existing AI models from OpenAI. Here is the log for the test example.

Since you haven't provided your settings or provided a log, the problem is probably caused by the settings themselves. First, make sure you're providing enough tokens for the model.
