laya-multilingual-coreml-snake

Laya typed decisions on Apple Silicon, using CPU + GPU. This is a portable Core ML bundle for laya-coreml, converted from 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.

pip install laya-coreml

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:

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.
