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.

Immutable artifact identity

Exact upstream Qwen revision used for quantization Not recorded

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.

License and attribution

The covered shared-base artifact is provided under the Apache License 2.0; see LICENSE. See NOTICE.md for the immutable source chain, modification statement, scope boundary, and attribution.

Alibaba Cloud, the Qwen authors, rippertnt, Hugging Face, llama.cpp, GGUF-my-repo, and their respective contributors do not endorse Lumen, this rehost, or applications that use it.
