GPT-4.1 and GPT-4o Fine-tuning Queued Indefinitely

I’m attempting to fine-tune GPT-4.1 and GPT-4o models, but both models have been stuck in queue for over 24 hours with no indication of expected wait times. In contrast, fine-tuning with the Mini models starts almost immediately. Reliable fine-tuning is essential for our workflow, and these unpredictable delays are significantly disrupting our process and rendering the fine-tuning API useless due to its inconsistent availability. Is there any guidance on why and how to deal with queue times for GPT-4.1 and GPT-4o fine-tuning jobs?
