Pipe Network released an open-source MLX port for Kimi K3 on July 28th. A streaming converter and REAP pruning reduce the model from 1.6 TB to about 350 GB, making it possible to run on a Mac Studio.

Run Kimi K3 on a Mac Studio 🫰

K3 is 2.8T parameters and 1.6TB on disk, which makes it impossible to run on Apple Silicon.

Until now.

Our MLX port is now open source: https://github.com/PipeNetwork/kimi-k3-mlx

To accomplish this, we solved two things:

1. We wrote a streaming converter that walks one layer at a time, so that mlx_lm doesn't need to materialize the whole model.

2. REAP pruning sits on top and scores all 896 experts against a calibration corpus to keep only ones your workload needs.

That's what brings K3 down to 350GB and inside a Mac Studio.
