MLX-Serve 26.11.1 rewrite: plugin architecture adds models and quants without recompiling

TheMoonMidas · x · 2026-10-29

MLX-Serve 26.11.1 is a full engine rewrite built around building blocks and plugins. Anyone can write a plugin in C/C++/Rust/Zig etc. to add new models, quant types, media engines, or faster alternatives without recompiling the engine. Launch plugins include TurboEXL3 and Deepseek Sushi STQ; there is no central registry — plugins must be downloaded and compiled from GitHub (the author suggests having an agent review the code for security). The accompanying TurboEXL3 article argues EXL3 should be the default format for MoE expert weights on Apple silicon, challenging the current MLX affine 4-bit / MXFP4 / NVFP4 defaults.
