Lumen Qwen3 1.7B shared-base GGUF

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.
