Kid's getting way too much hate for what seems to be quite a cool project! Oh he "just" put a UI in front of Trellis? Yes. He did. You didn't. Keep up the good work, gd3kr :)
The site's ad copy: "BlenderGPT is an advanced artificial intelligence program that creates 3D models from text or image prompts in ~20 seconds. It lets you synthesise fully textured meshes, then import directly to Blender with a shortcut or download the source files for use in any compatible software. We think it's really good, try it out for free now."
It's very deliberately posing itself as having their own proprietary algorithm, as opposed to just a wrapper around TRELLIS, whose team did the real work. There's nothing wrong with that, but not giving any credit or mention to the trellis team is in poor taste.
