Built up the initial dataset for a Character Swap Minimax H3 lora I'm training. It's pretty insane that codex can just whip this up using gpt image 2.5 directly via its imagegen tool. It can generate the scene, create a character reference, and do the edits to place that character in the scene. Gonna try training it on my 4090 machine via @ostrisai toolkit. If it works I'll open source the lora and dataset on Huggingface.
