How to make AI model ?

There are quite a few options. To have consistent facial and body shapes, use reference images for Veo 3 ultra. If you are proficient in Veo 3, it's great for creating content videos because it's inexpensive...

I'd recommend seedance. It has become one of the standout AI video models recently. If you use a consistent reference image and a good prompt, it does a solid job of keeping the same face and overall appearance across scenes

Higgsfield would be good fit to make not so hardcore content, for its ease of use, given you may not be able to understand complex comfy ui flows

like someone else mentioned in here, take pics of model from various angles and have gemini generate a model 360 sheet which will become your reference point for all videos.
