embed-qwen3 — Qwen3-Embedding-0.6B for Core AI (macOS 27)
Alibaba's Qwen3-Embedding-0.6B (Apache 2.0)
exported to an Apple Core AI .aimodel for on-device text embeddings and semantic search. Read by
swift-text-embedder and the
embed command-line tool.

The host tokenises (NFC, Qwen2's pre-tokeniser, end-of-text appended), pads on the left, picks the
shortest length that holds the text, and L2-normalises the output. Queries are embedded as
Instruct: <task>\nQuery: <text>, documents as they are, per the model card.
Fidelity
Against transformers 5.17 on the same inputs: tokenizer ids and masks identical over 13 texts at
both lengths (Unicode, code, newlines included); embeddings 125–126 dB PSNR, cosine ≥ 0.999999.
The fixed-length left padding changes an embedding by at most 3e-7 against the unpadded model.
