| # Hadamard MLX preview | |
| Text-only affine 2-bit/group-128 weights. Load with the bundled runtime: | |
| ```python | |
| import sys | |
| sys.path.insert(0, '/path/to/pack/runtime') | |
| from artifact import load_model | |
| model, config = load_model('/path/to/pack') | |
| ``` | |
| Install `runtime/requirements.txt` on Apple Silicon. Ordinary MLX loaders do not apply the required transforms. Vision and MTP are not included. | |
| `hadamard.json` uses the version-1 Prism contract accepted by MLX Swift's PrismHadamardConfiguration. Names refer to the saved MLX tensor namespace. GDN activations are already grouped in the bundled runtime; do not permute them again. Swift full-model loading still requires model integration; layer support alone is insufficient. | |
| Reload validation checks serialization, not model quality or cross-runtime equivalence. Tokenizer validation checks vocabulary IDs and BPE merge ranks; it does not certify pre-tokenizer behavior. The chat template is copied from the source GGUF. | |
