This model is maintained as part of the Mobile Model Playground, which records conversion provenance, checksums, compatibility, and mobile validation evidence.

Status: conversion candidate · Android emulator contract checked. No physical-phone performance claim is made yet.

Distribution

Hugging Face — international discovery and direct HTTPS download.
GitCode — domestic distribution through Git LFS.

Both endpoints publish the same Harzva-converted artifact. Verify the byte count and SHA-256 below after downloading from either endpoint.

Validation

Host smoke

Environment class: macOS arm64 host, Metal backend
Prompt: Q: What is 2+2? A:
Response: 2 + 2 = 4.
Prompt processing: 952.8 tok/s
Generation: 112.2 tok/s

This only verifies that the converted artifact loads and generates a sane answer on the host.

Android ARM64 emulator

Model load: 1,389 ms
First token: 8,026 ms
Generation: 0.289 tok/s
Artifact file size reported by the test: 456 MB

These numbers came from a low-performance Android ARM64 AVD. They are contract evidence, not phone performance. Peak PSS, temperature, power, sustained stability, and physical-device quality remain unverified.

Sanitized machine-readable records for the host, Android AVD, and GitCode post-publication checks are available under evidence/runs/. Hugging Face publication verification is tracked independently by the Mobile Model Playground so one distribution endpoint cannot inherit another endpoint's evidence.

Reproduce

See conversion/convert.sh. Reproduction requires Python conversion dependencies and a llama.cpp build containing llama-quantize.

MobileCore use

Import the GGUF as a text model and select the llama.cpp backend. Do not attach an mmproj or advertise visual/audio input for this artifact.

Known limitations

Q4_K_M was produced without an importance matrix.
Physical Android device results are not yet available.
The surviving conversion artifacts were verified, but a fresh byte-for-byte conversion transcript is still desirable for long-term provenance.
