Fine Tuning Stuck on Validating Files

API
1

I tried creating a fairly large GPT 4o Mini fine-tuning job (400MB). It stayed stuck on Validating Files for a few days, so I canceled the job to try again. It never got past validating files.

Today, I’m trying to fine-tune a much smaller job (2.5MB), and it’s still getting stuck on Validating Files. Is there any way to track what’s going on?

I’ve seen it taking a bit longer at the moment and I suspect that this due to higher traffic given the current offering to fine-tune for free.

You might want to try outside of business / peak hours.

Normally, a 2.5MB file should not take more than 5-10 min to validate.
