This card documents the single shared-base artifact lumen-qwen3-fast-shared-q4_k_m.gguf in ales27pm/lumen-qwen3-bootstrap-gguf. Lumen uses it as the common base for role-specific LoRA adapters in its local-first iOS runtime.

Pinned links: Lumen artifact, immediate-source artifact, and immediate-source card.

The Lumen file is byte-identical to the immediate-source file at the pinned revision. Lumen only renamed and re-hosted that GGUF; it did not convert, quantize, merge, or otherwise modify its bytes.

The immediate-source model card identifies Qwen/Qwen3-1.7B as the base, declares Apache-2.0, and describes GGUF conversion with llama.cpp through the GGUF-my-repo workflow. It does not record the immutable upstream Qwen commit used for the April 2025 conversion, so this card does not invent one.

Scope warning

This card's byte-identity and provenance statements apply only to lumen-qwen3-fast-shared-q4_k_m.gguf. The artifact-lineage revision also contains separate Lumen release-bake GGUF files. Those files are not the byte-identical rehost documented here, and this card does not establish their provenance or license status. They require separate documentation before any repository-wide licensing claim is made.

Intended use

The covered artifact is intended as a local GGUF base for a compatible llama.cpp runtime, including Lumen's role-adapter runtime. Model output is untrusted and must remain behind application-layer validation, permissions, approvals, privacy controls, and bounded tool execution.

Limitations

The exact upstream Qwen/Qwen3-1.7B revision used by the immediate-source quantizer is unknown.
Quality, safety, and performance depend on the runtime, prompt, sampling configuration, device, and any applied adapters.
This artifact is not itself an application safety or authorization system.
