Is there any way to just ignore this and do a retry or something else?

openai.APIError: The model produced invalid content. Consider modifying your prompt if you are seeing this error persistently.

This is an error we see frequently with gpt-4o-mini and is on the OpenAI side; we've been unable to solve it on the CF side. It has something to do with the model trying to use a tool in an invalid way

Yes I've gotten this with other toolchains as well

the error is deterministic for a certain tool JSON payload, it can't be retried

I mean for the record I don't use mini for anything

Unfortunately the tool in question are the ones CF relies on, I wish OpenAI would at least publish what confuses the model

I assume you mean the success and fail tools?

No, I had a way to replicate this on the first call. It's the success tools but in conjunction with a very specific setup of other messages

Is there some sort of prefix we can add to force it out of this error mode when it occurs ?
