MLX measured slower than Core ML on an iPhone 16 for this model, at matched fp32 precision and against the shipped Core ML fp16 build. These exporters only ever declared an MLX fp32 variant, so fp32-vs-fp32 is the fair and conservative comparison, and MLX still loses it.
The .pte and config.json are removed; each mlx/ dir keeps a NOTES.md with this model's own measurements. The exporter is retained in export-scripts so this can be re-tested against a future ExecuTorch/MLX release.
MLX for these models was only ever published on main / v0.10.0; no tag at v0.9.0 or below carried it. v0.9.0 and below are untouched.
