Bonsai-27B packed-Q1 native LoRA training release
This is a reproducible engineering release for native LoRA training directly against the packed Q1_0 Bonsai-27B base model in a pinned Prism/Mintplex llama.cpp tree.
The repository contains adapters, deterministic checkpoints, dataset shards, source changes, clean-build evidence, verification scripts, reports and an optional Linux/CUDA build. The 3.8 GB base GGUF is not redistributed.
Release status
What is proven
- Packed Q1_0 base weights remain immutable.
- Six LoRA tensors are optimized without a persistent expanded base model.
- Checkpoint save/reload is exact.
- Interrupted accumulation resumes deterministically.
- Independent resume branches produced byte-identical checkpoints, adapters and state fingerprints.
- Load/unload, quick soak, RAM and VRAM checks passed.
- The patch applies to commit
7529fdaaf99ffdc5ca71ace9c7409a56b27ad92fand selected targets build in a clean worktree.
LoRA targets
Total trainable LoRA values: 135,360.
Quality result
This was a tiny proof run, not a quality fine-tune.
- Train mean-token NLL, full minus zero adapter:
0.00021834747786 - Validation mean-token NLL, full minus zero adapter:
9.73401665583e-06 - Validation improved: no
The adapter is numerically connected and stable, but the proof run is too small to establish a quality gain.

- This is a proof-of-training release, not a broadly trained production LoRA.
- Validation NLL was slightly worse by
9.73401665583e-06. - The Linux build is environment-specific.
- The quick soak is not an hours-long production endurance test.
- Upstream source and base-model licenses and terms apply.
