NoobAI comes from Illustrious but their training goes way beyond using called vpred e621 or something like that from danbooru. So is not illustrious at all at least the vpred version. the epsilon ones are still somehow but only " ". If you want pure illustrious type then use base or find others that aren't mixed with noob epsilon. Flux loras only on Flux. Pony loras is a hit and miss you can use them but could have potential issues like fried gens ect.
