I have been trying to fine-tune gpt-4.1-2025-04-14 for a few days and no matter I try it doesn’t seem to ever move out of the queued state. I’ve waited 12+ hours and nothing ever happens. I can take the same training and validation data sets and they work fine on gpt-4.1-mini-2025-04-14. I have also…

Just got an update from the team: There was an issue that the engineers identified and fixed. Please restart any impacted jobs, and let us know if you are still seeing issues. We apologize for the inconvenience.

I am seeing the same issue, even though I didn’t wait 12 hours. Based on experience the jobs should have moved on by the time I cancelled them. Although the same issue occurred for me for both gpt-4.1-mini-2025-04-14 and gpt-4.1-2025-04-14. Will ping the team regarding this. Fingers crossed it wi…

4.1-mini isn’t working for me either now. Yes, I hope they fix it soon. It’s been a few days now.

I haven’t needed to wait this long I think since 2023 or something. It’s been stuck for hours, in “waiting state”. Can somebody from OpenAI at least maybe drop an announcement or something related to this? When might we expect it to get back up again?

I’m having the same issue. I had 1 waiting for over 12 hours until I canceled it. I have tried 3 times, I’m on hour 3 on the 3rd attempt.

After the recent “We’re having trouble accessing your files right now” error with fine-tuning was fixed (thank you!), I ran a few successful fine-tuning jobs on base model gpt-4o-mini-2024-07-18. Unfortunately, now similar fine-tuning jobs have been stuck in the “Waiting…” state for several hours, …

It seems like they fixed it now. I got one run through …

still stuck at waiting (base: gpt-4.1-nano-2025-04-14).

When you say you got 1 through, did a stuck one finally complete or did you start a fresh one and it went through? I’m asking so I can gauge if I should cancel one that’s been stuck for 18+ hours and start new or not.

Has fine-tuning worked for anyone after the reported fix? We’re still experiencing the same issue: none of our fine-tuning jobs have moved beyond “Files validated, moving job to queued state” since March 23rd. We tried running some jobs again this morning, but we’re still seeing the same problem …

4.1-mini isn’t working for me either now. Yes, I hope they fix it soon. It’s been a few days now. check
