# laya-multilingual-coreml-snake

**Laya typed decisions on Apple Silicon, using CPU + GPU.**
This is a portable Core ML bundle for [laya-coreml](https://github.com/mizorewww/laya-coreml),
converted from [convaiinnovations/laya-multilingual](https://huggingface.co/convaiinnovations/laya-multilingual).
It outputs `choice`, `score`, and `noul` probabilities with **zero generated tokens**.
Inference needs no PyTorch, Transformers, MLX, remote code, or cloud API.

## Run

Apple Silicon, macOS 15+, Python 3.11–3.13. Tested on M3 Max / macOS 27.2.

```bash
pip install laya-coreml
```

```python
import laya_coreml as laya

agent = laya.load("aac6fef/laya-multilingual-coreml-snake")  # Download once; Core ML runs locally.
result = agent.predict(
    "The customer asks for a refund of a duplicate payment.",
    {"refund": {"type": "noul", "instructions": "Does the customer request a refund?"}},
)
print(result["answers"])
```

To download explicitly and then run entirely offline:

```bash
hf download aac6fef/laya-multilingual-coreml-snake --local-dir models/snake
pip install 'laya-coreml[demo]'
laya-coreml-snake --model models/snake --fps 12
```

Use `laya.load("aac6fef/laya-multilingual-coreml-snake", local_files_only=True)` for a cached snapshot or pass a
local directory. Use `revision="<Hub commit SHA>"` to pin a remote revision.

## Format and fidelity

This FP16 export retains the original model architecture and decision schema. The enumerated-length GPU export is the validated general-purpose configuration.

The matching fixed B3/L64 Snake export agreed with MLX on 600/600 actions across two 300-step trajectories, with zero deaths and zero safety interventions. It is a specialized 64-token export, not the full-context general-purpose model.

The exported capacity is **64 total tokens**, batch **3**,
and **4** option slots. Questions/options and state share this budget.
The ANE short exports reject over-capacity prompts. Snake uses planner features and a
visible optional cycle safety shield; survival is not a claim of unaided game intelligence.

`coreml_config.json` records shapes, source revisions and per-file SHA256 checksums.
`validation.json` contains the packaging-time validation. Port fidelity on this regression
suite does not establish general task accuracy or preserved calibration on arbitrary inputs.

## Performance and limits

The multilingual **ANE L96 FP16** runtime measured **4.98 / 5.31 ms P50 / P95** for
one short question on M3 Max; W8 measured **4.88 / 5.23 ms**. Whole-system energy per
decision improved **2.78× / 3.19×**, respectively, against compiled MLX FP16 in that
experiment. Those numbers apply to the named short ANE variants, not every bundle,
long contexts, or complete Snake frames. The requested 10× improvement was not achieved.
