# NLLB-200 Core ML 1024 — FLOAT32 (private snapshot)

**Private** Hub repo: full **float32** Core ML `mlpackage` tree (encoder + KV decoder init/step), ~**5 GB** on disk. Same layout as local `output/nllb200-coreml-1024`.

This is a **separate repository** from:

- Public or other `nllb200-coreml-1024` variants on the Hub
- [nllb200-coreml-1024-pal8](https://huggingface.co/aoiandroid/nllb200-coreml-1024-pal8) (8-bit weight-only palettized, ~1.3 GB)

Use **float32** when you need maximum numerical stability; use **pal8** for smaller download and faster inference on tested Mac setups.

## Base model (official)
