The zoo includes ports of Mapika decider, Kev, Liquid d1, OpenThai, Laya and a Qwen scorer. These are existing models packaged by John-rocky, not newly trained models. Supported devices differ between ports. A result measured on a Mac tells you nothing conclusive about performance on an iPhone.
How you can use it
The maker provides examples for particular devices and checks answers against the original models. Use those to choose a port for an Apple app that needs local choices, ratings or yes/no answers instead of written replies. Some ports accept images. Check which hardware and Apple app-building software your chosen model needs.
