Model for testing.

This is the checkpoint model I used to test the pony lora model.

Regarding the version numbers vX.0 and vX.1: Compared to vX.0, vX.1 slightly enhances the visual experience in 2D, 2.5D, and 3D. The transition from v0.5 to v1.1 primarily focuses on 2D effects, with v1.1's 2D style beginning to lean towards 2.5D. The shift from v2.0 to v2.1 is dominated by 2.5D effects, where v2.1's 2.5D style starts to tilt towards 3D. The progression from v3.0 to v3.1 favors 3D, with v3.1's 3D style having a minor enhancement over v3.0. However, the entire v3.X series does not fully achieve pure 3D effects.
