ASH-P7-4B

A QLoRA fine-tune of Qwen3-4B-Instruct-2507, trained on real pull-request and issue review discussions from Cubyz, an open-source voxel sandbox game written in Zig.

What this is

A behavior fine-tune, not a fact database. It's trained on PR/issue review judgment โ€” real maintainer code-review reasoning (architecture critique, debugging diagnosis, "why this change is/isn't good"). It shapes how the model reasons and explains, not what it remembers.

This model is meant to be run with RAG (retrieval-augmented generation), not standalone. Facts about Cubyz should come from a retrieval pipeline that grounds answers in real docs/codebase/PR history; this fine-tune supplies the judgment and explanation style on top of that.

Accuracy on a 144-question Cubyz domain benchmark, served with RAG grounding: 99.0โ€“99.3%.

Files in this repo

File What it is
ASH-P7-4B-q4.gguf Merged model, Q4 quantized (~2.4GB) โ€” ready to run directly with Ollama or llama.cpp.
ASH-P7-4B-f16.gguf Merged model, full precision (~7.5GB) โ€” for anyone who wants to requantize themselves.
adapter_model.safetensors + adapter_config.json The raw LoRA adapter (~127MB) โ€” apply this to the base model yourself instead of using a pre-merged GGUF.

Quick start (Ollama)

``` ollama create ASH-P7-4B -f Modelfile ``` with a Modelfile containing: ``` FROM ./ASH-P7-4B-q4.gguf PARAMETER num_ctx 16384 ```

License

The base model (Qwen3-4B-Instruct-2507) is Apache 2.0, and this repo is labeled Apache 2.0 to match. One thing worth knowing: the fine-tuning data is derived from PR/issue review discussions on Cubyz, which is itself GPL-3.0 licensed. Whether that meaningfully affects the license status of model weights trained on that data (as opposed to the underlying source code itself) is genuinely unsettled territory, not something this repo resolves for you โ€” flagged here so you have the full picture rather than an unqualified license claim.
