K2-Horizon-MoVA-36B-A4B-MLX-4bit

4-bit affine (group size 64) MLX conversion of IFM/K2-Horizon-MoVA-36B-A4B for Apple Silicon via mlx-lm.

The K2 MoVA architecture has no stock mlx-lm implementation, so this repo ships a custom k2_horizon.py, referenced from config.json (model_file). MoE/MoVA router matrices are kept in BF16; all large projections are 4-bit.

Measured on a 64 GB M4 Pro Mac mini: ~43 tok/s single-stream decode, 18.9 GB peak RSS, perplexity 2.1-8.6 on generic prose/code.
