fal Adds LoRA Training for MiniMax H3, Starting With an Open-Source Realism People LoRA

Custom LoRA training for MiniMax H3 is now live on fal, and the company demonstrated it with Realism People, an open-source LoRA it says pushes the model toward photorealistic humans.

• The trainer targets MiniMax H3. It fine-tunes the open-weight model that generates video, image, audio, and text.
• Realism People ships open source. fal posted the LoRA weights to Hugging Face, tuned for skin, eyes, and motion.
• The trainer covers several input modes. fal points to entry points for text-to-video, image-to-video, first-last-frame, and reference-to-video.
• More LoRAs are coming. fal says additional LoRAs are on the way.

Realism People targets photorealistic humans

fal trained Realism People to show what the new trainer produces, describing it as a LoRA that pushes H3 toward raw, photorealistic humans with a focus on skin, eyes, and motion. fal posted the weights as an open-source release on Hugging Face, so you can run the LoRA directly or study how it was built before training your own.

Because it is an open release rather than a hosted-only feature, the LoRA can be pulled into other workflows built around H3 rather than staying locked to fal's interface. We have also compared reference images versus LoRAs for holding a consistent look across shots.

Training on an open-weight video model

A LoRA lets you steer a base model toward a specific look, subject, or style without retraining the whole thing, which is how fal can layer training on top of H3. If the term is new to you, we broke down what a LoRA is for non-technical readers.

fal lists trainer entry points spanning text-to-video, image-to-video, first-last-frame, and reference-to-video, so a custom LoRA can attach to more than one generation path. Teams wanting a consistent character or aesthetic across shots can tune H3 on their own material and reuse the result instead of prompting it blind each time.

A trainer and reference LoRA make H3 customizable

The MiniMax H3 launch gave creators an open-weight model that unifies multiple generation types. Adding a trainer and a reference LoRA turns that base model into something you can customize, and the open-source Realism People release gives a concrete starting point rather than a closed demo. With fal signaling more LoRAs to follow, the near-term value is a growing library of tunable looks for anyone already generating with H3.
