I Gave 8 AI Models the Same Prompt (Pick a Winner)
Provides AI filmmakers with a head-to-head benchmark comparison of eight major video generation models using identical prompts and character references.
What this lesson covers
Diego Galvao conducts a standardized comparison of eight AI video generation models using identical prompts, character reference sheets, and settings inside Higgsfield. He demonstrates the outputs from models like Kling 4.0, Seedance 2.5, and MiniMax H3 to compare facial consistency, physics interactions, and prompt adherence.

- 00:37 ↗
Standardizing prompt, character reference sheet, aspect ratio, and resolution settings across models enables an unbiased model comparison.
- 01:14 ↗
Model constraints vary, with MiniMax defaulting to 2K resolution while Gemini Omni Flash limits video output duration to 10 seconds.
- 03:21 ↗
Certain video models like Grok Video 1.5 may downgrade generation resolution (e.g., to 720p) when processing character reference images.

Comparing AI video model quality requires examining detailed cues such as facial consistency across camera moves, realistic object interactions, and sand physics during motion.
Workflow outlined in the video
- Upload a multi-angle character reference sheet containing close-up facial features and full-body views into your video generation studio.
- Craft a detailed prompt describing the character's clothing, setting, lighting, and specific physical actions.
- Set matching render parameters across models, including 10-second duration, 16:9 aspect ratio, and 1080p resolution.
- Generate outputs using identical inputs across multiple models within Higgsfield.
- Compare side-by-side results focusing on motion sequence ordering, environment interaction physics, and character feature lock.
