Llama 3.1 8B Instruct is the smallest model in Meta's Llama 3.1 collection, tuned for multilingual dialogue. It takes and writes text, with a 128K-token context.
A 4-bit MLX build is about 4.5 GB; on mlx.app's estimate it fits a Mac with 8 GB of memory.
Open weights under the Llama 3.1 Community License, a custom licence with conditions. Meta's own repository asks you to accept the licence before downloading; the MLX build doesn't. Run locally, nothing leaves your Mac.
How to Get It
