This sounds interesting to me! I will check it out in more detail. I saw 3.5-turbo mentioned which is more expensive and as I understand it, it's usually less good as a base model, if I see 3.5-turbo before I see 4o-mini, and don't see 4o-mini, I might wonder if things are behind! I hope that's fair feedback for a quick reaction. I have done a bunch of fine-tuning before, locally and with 4o-mini, and there's often a lot of time spent suboptimally on wrangling data so I'm interested in this category of product for sure, if it helps more than it costs me.
