tried this:

   Generate Earth-like planet (10,000km diameter, 24h rotation, 23° axial tilt).
   Single supercontinent spanning 40% of surface area, centered on equator.
   Remaining 60% is ocean.

   Continent features:
     - Central desert plateau at 1,500m elevation, approximately 2,000km × 1,500km
     - Mountain range along entire eastern continental margin, peaks 4,000-6,000m
     - Gradual elevation decrease toward western coast
Looks like it understood only „earth-like“ and 23° axial tilt, the map is fractal.

Thanks for trying it out. I think I need to change the model that generates the preset. It’s currently using gpt-5-mini.

I have tried a few things. Honestly this feels like some sort of very lazy vibe-coded app that superficially looks cool but does not actually produce anything of any value.

Yep, it’s just a vibecoded project, and the model used for the preset isn’t great since I’m using gpt-5-mini. I’ll change the model. It’s just a fun weekend project only
