Unable to fine-tune davinci


I’m using a training file with ~2500 samples (the longest prompt has about ~500 tokens) and validation file ~350 samples.

I was able to fine-tune curie and ada using these train and validation files. However, when I try to fine-tune davinci, the status never changes to “running”, instead it shows “failed” immediately after submitting the fine-tune job.

I tried to fine-tune davinci only using the validation file ( used validation file with ~350 samples as the training file, and didn’t pass any file to validation_file parameter). The fine-tune job status changed to “running”.

Could you please tell me what’s going here? I have credits ~250$ on my account. Any help will be highly appreciated
