# Lemrd — Gemma 4 31B Dense — MLX 4-bit

The largest dense member of the Lemma model family by Lethean. An EUPL-1.2 fork of Gemma 4 31B with the Lethean Ethical Kernel (LEK) merged into the weights.

This repo hosts the **MLX 4-bit** build for native Apple Silicon inference via [`mlx-lm`](https://github.com/ml-explore/mlx-lm) and [`mlx-vlm`](https://github.com/Blaizzy/mlx-vlm). For the GGUF playground (Ollama, llama.cpp) see [`lthn/lemrd`](https://huggingface.co/lthn/lemrd). For the unmodified Google base see [`LetheanNetwork/lemrd`](https://huggingface.co/LetheanNetwork/lemrd).
