They're planning on retiring the classic trainer on the 16th. Less than two weeks notice!

We don't even get two weeks notice before they pull it! With the constant downgrades to the trainer I'm looking less and less likely to even make it to 250 LoRA.
Known issues with new trainer just from my own experience
The layout for actually tagging images is far worse. In many ways manually making and editing txt files is less work.
This video still fails to upload every single time, even though it works just fine on the old trainer (I reported this a month ago, got a response, still not fixed). The problem seems to even survive Imgur's processing of the video file so you can see it for yourself.
It's AI Toolkit based, which fails half+ the time, often producing pure corrupted garbage. (I know the old trainer is now AI Toolkit only too, but AI Toolkit is such utter garbage I need to mention it)
A single image deemed to be highly rated costs yellow buzz to train. That's based on the highly false positive prone rating system that consistently applies random R ratings to everything.
It really tries to push you away from Illustrious (the site's most popular model) and into more expensive models.
When your model is held for moderation approval it just doesn't progress and you have no idea why
