+# Command add-ons for Qwen2.5 0.5B
+
+Three small LoRA adapters that turn a plain-language request into a command line, one tool each.
+They run in the browser with [wllama](https://github.com/ngxson/wllama) or natively with llama.cpp,
+on top of one shared base model, and are published as signed releases in
+[modelXare](https://modelxare.com) by weXare.
+
+| File | Tool | Example request | Answer |
+|---|---|---|---|
+| `git.gguf` | git | undo my last commit but keep the changes | `git reset HEAD~1` |
+| `ffmpeg.gguf` | ffmpeg | extract the audio from talk.mp4 as an mp3 | `ffmpeg -i talk.mp4 -vn talk.mp3` |
+| `imagemagick.gguf` | ImageMagick | make a 200px thumbnail of photo.jpg | `magick photo.jpg -thumbnail 200x output.jpg` |
+
+Each file is 5.9 MB (f16, rank 8, 16 layers).
+
+## Base model
+
+They apply only to
+[`qwen2.5-0.5b-instruct-q4_k_m.gguf`](https://huggingface.co/Qwen/Qwen2.5-0.5B-Instruct-GGUF/blob/9217f5db79a29953eb74d5343926648285ec7e67/qwen2.5-0.5b-instruct-q4_k_m.gguf)
+(491 MB, SHA-256 `74a4da8c9fdbcd15bd1f6d01d621410d31c6fc00986f5eb687824e7b93d7a9db`). One copy of the
+base serves all three, and switching between them needs no reload.
+
+## Prompt
+
+Each adapter was trained with one fixed system prompt and the request as the user message, using the
+base model's own chat template. Use the same system prompt; the modelXare releases carry it in their
+`command-generation` operation. ffmpeg and ImageMagick answer `UNSUPPORTED` / `unsupported_request`
+when the tool can't do what was asked.
+
+```sh
+llama-cli -m qwen2.5-0.5b-instruct-q4_k_m.gguf --lora git.gguf -cnv \
+  -sys "You are a Git command translator. Read the user's natural-language request and reply with ONLY the exact git CLI command(s) that fulfill it. Use a single line when one command is enough; use newlines for a short sequence. Do not wrap commands in markdown, quotes, or explanation."
+```
+
+## Training
+
+LoRA (QLoRA on `mlx-community/Qwen2.5-0.5B-Instruct-4bit`) with mlx-lm: rank 8, 16 layers, learning
+rate 1e-4, batch 4, completion-only loss, early stopping on validation loss. Converted to PEFT layout
+and then to GGUF with llama.cpp's `convert_lora_to_gguf.py`.
+
+| Adapter | Training rows | Best checkpoint (val loss) |
+|---|---|---|
+| git | 4,592 | 0.047 |
+| ffmpeg | 2,504 | 0.169 (iter 300) |
+| ImageMagick | 2,505 | 0.100 |
+
+The git data comes from templates with slot pools and typing noise. The ffmpeg and ImageMagick data
+was generated by a larger language model from a task description, then checked by script.
+
+## Evaluation
+
+211 held-out requests per tool, greedy decoding, through native llama.cpp (node-llama-cpp) with the
+q4_K_M base. Many test rows give an output file name the request never mentioned, so the second
+column also accepts a different output file name when the request names none.
+
+| Adapter | Exact match | Exact match, any unnamed output name | Base model alone (exact) |
+|---|---|---|---|
+| git | 83% | 86% | 30% (first 60 rows) |
+| ImageMagick | 65% | 80% | 2% (first 60 rows) |
+| ffmpeg | 35% | 68% | 0% (first 60 rows) |
+
+## Limits
+
+- Commands are suggestions: read them before running them. They can be wrong, and some (`git reset
+  --hard`, `git push --force`, overwriting output files) destroy data.
+- English requests only. One tool per adapter; requests that need several tools are out of scope.
+- Unusual flags, filters and long multi-step requests are the weakest cases, ffmpeg most of all.
+  Known misses: "discard my changes to README.md" gave `git checkout -- . README.md` (which discards
+  every file's changes), and trimming or GIF requests often get the wrong ffmpeg flags.
+- ImageMagick answers sometimes write over the input file (`magick photo.jpg -rotate 90 photo.jpg`).
