I trained an open-source realism LoRA for MiniMax H3 - it makes generated people actually look real (weights inside)

Update : New version is ready and online , should be much better, fully functionnal on ComfyUI, and you can find before/after here : https://huggingface.co/fal/MiniMax-H3-Realism-People-LoRA/blob/main/before-after-comparison.mp4 I spent the last week obsessing over one thing: making AI-generated humans stop looking AI-generated. The result is Realism People, an open-source LoRA for MiniMax H3, and I'm pretty happy with how it turned out. What it does: skin keeps its texture instead of going plastic, eyes and micro-expressions stay coherent, lighting behaves like a film set, and motion gets a subtle handheld, documentary feel. It also keeps H3's native synchronized audio. How it was selected: I trained 16 different configurations across two dataset versions and picked the winner through 100 same-seed A/B duels (same prompt, same seed, adapter on vs off - the only honest way to compare). The winner was the slow-cooked run: rank 16, 5,000 steps at a low learning rate. Details: - Weights (open source): https://huggingface.co/fal/MiniMax-H3-Realism-People-LoRA - Trigger word: start your prompt with r34l1sm - Scale 1.0 is the intended strength, 0.6-0.8 for a lighter touch - Works with H3's LoRA endpoints: text-to-video, image-to-video and reference-to-video - License: follows the MiniMax H3 community license Before/after in the video: same prompt, same seed, base model on the left, LoRA on the right. Happy to answer questions about the process. submitted by /u/Affectionate-Map1163 [link] [comments]
