Hunyuan vs. Runway Gen-3: Which AI Model Creates the Best Photorealistic Video in Architecture ?
.
As of January 2025, Hunyuan is one of the best photorealistic text-to-video models that can run locally on ComfyUI. But how does it compare to Runway Gen-3, a cloud-based image-to-video model?
.
While they aren't a direct apple-to-apple comparison, both tools aim to generate high-quality, cinematic AI videos—but they take different approaches. In this video, we’ll:
.
🔹 Install and run Hunyuan in ComfyUI
🔹 Showcase test results from both models
🔹 Compare how they handle motion, realism, and consistency
🔹 Discuss which works best for architectural visuals
.
Since this channel focuses on architecture, mood, and atmosphere, we'll analyze how each model performs in an architectural context and which might be the best choice for creating compelling AI-generated visuals.
