# Nacrith GPU

Advanced lossless compression using a neural language model (SmolLM2-135M) + arithmetic coding.

Supports both **text** (NC01) and **binary** (NC02) compression.

- **Text:** ~15% compression ratio -- 2.5x better than gzip
- **Binary:** Hybrid format -- text regions neural-compressed, binary regions gzip/lzma-compressed
