122
+
123
+ You may add Your own copyright statement to Your modifications and
124
+ may provide additional or different license terms and conditions
125

128
+ the conditions stated in this License.
129
+
130
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
131
+ any Contribution intentionally submitted for inclusion in the Work
132
+ by You to the Licensor shall be under the terms and conditions of
133
+ this License, without any additional terms or conditions.

+ with Licensor regarding such Contributions.
137
+
138
+ 6. Trademarks. This License does not grant permission to use the trade

+ PARTICULAR PURPOSE. You are solely responsible for determining the

152
+
153

156
+ negligent acts) or agreed to in writing, shall any Contributor be
157
+ liable to You for damages, including any direct, indirect, special,
158
+ incidental, or consequential damages of any character arising as a
159
+ result of this License or out of the use or inability to use the
160
+ Work (including but not limited to damages for loss of goodwill,
161
+ work stoppage, computer failure or malfunction, or any and all
162
+ other commercial damages or losses), even if such Contributor

164
+
165

16
+
17
+ **Laya typed decisions on Apple Silicon, using CPU + GPU.**
18
+ This is a portable Core ML bundle for [laya-coreml](https://github.com/mizorewww/laya-coreml),
19
+ converted from [convaiinnovations/laya-multilingual](https://huggingface.co/convaiinnovations/laya-multilingual).
20
+ It outputs `choice`, `score`, and `noul` probabilities with **zero generated tokens**.
21
+ Inference needs no PyTorch, Transformers, MLX, remote code, or cloud API.
22
+
23
+ ## Run
24
+
25
+ Apple Silicon, macOS 15+, Python 3.11–3.13. Tested on M3 Max / macOS 27.2.
26
+
27
+ ```bash
28
+ pip install laya-coreml
29
+ ```
30
+
31
+ ```python
32
+ import laya_coreml as laya
33
+
34
+ agent = laya.load("aac6fef/laya-multilingual-coreml-snake") # Download once; Core ML runs locally.
35
+ result = agent.predict(
36
+ "The customer asks for a refund of a duplicate payment.",
37
+ {"refund": {"type": "noul", "instructions": "Does the customer request a refund?"}},
38
+ )
39
+ print(result["answers"])
40
+ ```
41
+
42
+ To download explicitly and then run entirely offline:
43
+
44
+ ```bash
45
+ hf download aac6fef/laya-multilingual-coreml-snake --local-dir models/snake
46
+ pip install 'laya-coreml[demo]'
47
+ laya-coreml-snake --model models/snake --fps 12
48
+ ```
49
+
50
+ Use `laya.load("aac6fef/laya-multilingual-coreml-snake", local_files_only=True)` for a cached snapshot or pass a
51
+ local directory. Use `revision="<Hub commit SHA>"` to pin a remote revision.
52
+
53
+ ## Format and fidelity
54
+
55
+ This FP16 export retains the original model architecture and decision schema. The enumerated-length GPU export is the validated general-purpose configuration.
56
+
57
+ 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.
58
+
59
+ The exported capacity is **64 total tokens**, batch **3**,
60
+ and **4** option slots. Questions/options and state share this budget.
61
+ The ANE short exports reject over-capacity prompts. Snake uses planner features and a
62
+ visible optional cycle safety shield; survival is not a claim of unaided game intelligence.
63
+
64
+ `coreml_config.json` records shapes, source revisions and per-file SHA256 checksums.
65
+ `validation.json` contains the packaging-time validation. Port fidelity on this regression
66
+ suite does not establish general task accuracy or preserved calibration on arbitrary inputs.
67
+
68
+ ## Performance and limits
69
+
70
+ The multilingual **ANE L96 FP16** runtime measured **4.98 / 5.31 ms P50 / P95** for
71
+ one short question on M3 Max; W8 measured **4.88 / 5.23 ms**. Whole-system energy per
72
+ decision improved **2.78× / 3.19×**, respectively, against compiled MLX FP16 in that
73
+ experiment. Those numbers apply to the named short ANE variants, not every bundle,
74
+ long contexts, or complete Snake frames. The requested 10× improvement was not achieved.

82
+ - Original checkpoint: `convaiinnovations/laya-multilingual` at `052592a15d198d9ad47da779604259b10b47b7aa`.
83
+ - Original weights SHA256: `9d628fd971b700382ac6f65920a86f149777b2e748e0c955fb3b19695aa8f204`.
84
+ - Upstream implementation: [NandhaKishorM/laya](https://github.com/NandhaKishorM/laya),
85
+ commit `6a5819129eb220570792e417e49723d697efd76f`.
86
+ - Original models and code are by Convai Innovations and contributors, Apache-2.0.
87
+ - Independent conversion; not an official Convai Innovations or Apple release.
88
+
89
+ See `LICENSE` and `NOTICE`. Model quality and task/language limitations originate
90
+ with Laya; this runtime is an inference port, not a newly trained decision model.
