Google disabled createTunedModel action?

I was able to tune gemini 1.5 flash model through API, but it failed a few days ago.
I tried to find a model that supports the action createTunedModel and found nothing. Did Google disabled this action?

Hey @angusma , tuning has been removed from the Gemini Developer API. For fine-tuning, we now recommend using the Vertex AI SDK, which provides full support for model tuning workflows.
