Independent Core AI conversion of LiquidAI/d1-3B for text and image decisions.
Upstream: https://huggingface.co/LiquidAI/d1-3B

The upstream checkpoint, upstream code and converted weights are governed by the
LFM Open License v1.0. A copy of the license accompanies this distribution.

The conversion uses 1x1 convolution projections, activation scaling,
tanh-form SiLU and a split FFN. The language backbone and SigLIP2 vision tower
are exported as FP16 Core AI assets for the Apple Neural Engine. Tokenization,
image preprocessing, token-embedding lookup, the FP32 multimodal projector,
and option readout run on the host CPU. The model has not been retrained.

Independent Core AI conversions of vllm-sr/d3-nano and vllm-sr/d3-mini,
fine-tuned from Qwen/Qwen3.5-2B and Qwen/Qwen3.5-4B, for text and image decisions.

Revisions are pinned in src/tinkerbox_ane/d3/__init__.py and recorded in exported manifests.

Their checkpoints, upstream code and converted weights are governed by the
Apache License 2.0 (LICENSES/Apache-2.0.txt). The language backbone runs as
FP16 Core AI stages and the vision tower as an FP16 Core AI asset on the Apple
Neural Engine; tokenization, image preprocessing, position tables,
token-embedding lookup and option readout run on the host CPU. The models
have not been retrained. This project is not affiliated with or endorsed by

OmniVoice integration:
Upstream code: https://github.com/k2-fsa/OmniVoice (Apache-2.0).
Checkpoint: https://huggingface.co/k2-fsa/OmniVoice
Revision: c5fdb5ccb189668d56333f77ba2629f4cd7535f4
OmniVoice checkpoint and derived weights are licensed CC-BY-NC.
The Qwen3 transformer is converted independently; CPU speech processing and
sampling use the separately installed upstream omnivoice package.
