Gemini 1.5 Flash tuning support removed on free tier?

We are facing the same issue - Gemini-1.5-flash-001-tuning is not found for API version v1beta. The worst part is that we can’t access our finetunes, and as far as I know, there is no option to move them to Vertex. We are yet to receive an explanation. Here is our GitHub issue, we may get an update there: Gemini-1.5-flash-001-tuning is not found for API version v1beta · Issue #969 · googleapis/python-genai · GitHub.
