# Lemma — Gemma 4 E4B — MLX 8-bit
The mid-sized member of the Lemma model family by Lethean. An EUPL-1.2 fork of Gemma 4 E4B with the Lethean Ethical Kernel (LEK) merged into the weights.
This repo hosts the **MLX 8-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/lemma`](https://huggingface.co/lthn/lemma). For the unmodified Google base see [`LetheanNetwork/lemma`](https://huggingface.co/LetheanNetwork/lemma).
