Reproducible evidence

The repo keeps public claim-to-evidence mapping, trimmed logs, and dated rerun notes instead of hand-wavy success claims.

Termux-first workflow

Helper scripts, minimal patches, and setup notes document the Termux-side path that actually worked on a real Android device.

Monitoring helpers

Optional Termux and Windows-side monitors make it easier to inspect Android-side load without confusing those views with benchmark instrumentation.

Overview ​

bitnet-android-lab is a public lab notebook for trying QVAC Fabric BitNet LoRA fine-tuning on a real Android phone through Termux and adb forward SSH.

The repository is intentionally narrow:

  • one-device evidence rather than broad Android compatibility claims
  • a patched local Termux source-build path rather than a stock Android bundle story
  • public-facing scripts, patches, and evidence instead of bundled model weights or datasets

Verified Snapshot ​

  • Device path verified again on March 25, 2026: Xiaomi 2409BRN2CL / Redmi 14C, Android 15, Mediatek MT6769, Mali-G52 MC2
  • Verified success points: patched Termux build, TQ1 published-adapter inference, TQ2 checkpoint progression, TQ2 fast checkpoint inference
  • Not verified: treating the b7336 Android release asset as a ready-to-run Termux CLI bundle
  • Throughput figures are single-run tok/s references, not sustained benchmarks

Start Here ​

  1. Read Termux Setup.
  2. Review Experiment Log for dated outcomes and throughput notes.
  3. Read Limitations before generalizing any result.
  4. Compare public claims against Evidence Map.

Monitoring ​

The repository includes both Termux-side and Windows-side observation helpers:

  • gotop, htop, and bmon via the optional Termux installer
  • a Windows adb watcher with memory and swap bars, per-core CPU usage bars, frequency lines, and dumpsys summaries

These tools are useful for live inspection but should not be treated as benchmark instrumentation.

Latest Release ​

Single-device lab evidence, not a general Android compatibility claim.

Released with public-facing notes, patches, and evidence.
