Model gpt-4.1 is not available for fine-tuning or does not exist

API

We are Tier 5, I don’t understand why we cannot fine tune for 4.1 when they clearly state in the docs that fine tuning is available?

{
“error”: {
“message”: “Model gpt-4.1 is not available for fine-tuning or does not exist.”,
“type”: “invalid_request_error”,
“param”: null,
“code”: “model_not_available”
}
}

I have a wild guess that maybe there is no alias (yet) for the precise model?

When using the dashboard, there is a list of available models for fine-tuning. Maybe exactly one of those needs to be used for now.

Could you try using gpt-4.1-2025-04-14 as model? :thinking:
