+# naderu-geek-py-0.5b
+
+**A small coding assistant by [Naderu](https://naderu.com) — a BytesBrains Pte. Ltd. venture.**
+
+`naderu-geek` is a compact, specialised coding model. It is a **portfolio / demonstration**
+piece: a LoRA fine-tune of an open coding base that gives the model a recognisable
+`naderu-geek` identity and a clean, commented Python style. It demonstrates Naderu's
+model-engineering pipeline — data → training → evaluation → release — end to end, on a
+deliberately small footprint.
+
+> **Status: released (v0.1.0).** Trained 2026-07-14 (LoRA fine-tune, merged) and passed its
+> qualitative smoke eval — see **Evaluation** below. Nothing here is a capability claim — see
+> **Limitations**.
+
+> This is an honest demonstration piece, **not** a state-of-the-art model. Its coding
+> ability is essentially that of its base; the fine-tune adds identity and style, not new
+> capability. See **Limitations**.
+
+## Provenance
+
+- **Fine-tuned from:** [`Qwen/Qwen2.5-Coder-0.5B-Instruct`](https://huggingface.co/Qwen/Qwen2.5-Coder-0.5B-Instruct) (Apache-2.0)
+- **Method:** LoRA (r=16, α=32; ~8.8M trainable params, 1.75%) on attention + MLP projections, adapter merged into the base
+- **Training data:** a small, Naderu-authored instruction set (39 examples: identity + idiomatic Python) — license-clean, included in our repo
+- **Precision:** trained in fp32; merged weights distributed in **bf16** (matching the base's format)
+- **License:** Apache-2.0 (inherits the base model's terms)
+
+## Intended use
+
+- A lightweight Python coding helper: small functions, snippets, explanations.
+- A reference example of a Naderu specialised-model release (card + provenance + eval).
+
+**Out of scope:** production code generation at scale, non-Python languages, security-
+sensitive code, or any use where correctness must be guaranteed without review.
+
+## How to use
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "bytesbrains/naderu-geek-py-0.5b"
+tok = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id)
+
+messages = [
+    {"role": "system", "content": "You are naderu-geek, a focused coding assistant by Naderu (naderu.com). You write clean, correct, well-commented code and explain briefly."},
+    {"role": "user", "content": "Write a Python function to check if a number is prime."},
+]
+enc = tok.apply_chat_template(
+    messages, add_generation_prompt=True, return_tensors="pt", return_dict=True
+)
+out = model.generate(**enc, max_new_tokens=200, do_sample=False)
+print(tok.decode(out[0, enc["input_ids"].shape[1]:], skip_special_tokens=True))
+```
+
+The model is chat-templated (Qwen2 template). The system prompt above is the one it was
+trained with; keeping it yields the most on-style responses.
+
+## Evaluation
+
+<!-- EVAL:START -->
+**Suite:** `eval/suites/naderu-geek/run_eval.py` (qualitative smoke, greedy decode) ·
+**Run:** 2026-07-14 · **Result: PASS**
+
+| Check | Outcome |
+|-------|---------|
+| Identity recognised (`Who are you?` → names `naderu-geek`) | ✅ yes |
+| Coherent, runnable Python (3 in-suite coding prompts) | ✅ 3/3 |
+
+Observations (honest):
+
+- **Identity imprinted and robust.** It reliably self-identifies as `naderu-geek` by Naderu,
+  and on a held-out prompt (*"Are you ChatGPT or made by OpenAI?"*) it correctly denies and
+  states its open-base provenance — i.e. the identity generalises beyond the exact training phrasings.
+- **Clean Python style generalises.** On held-out tasks not in the training set (mean of a list,
+  nth triangular number) it produced correct, type-hinted, docstring'd functions in the same
+  house style — so the fine-tune transfers *style*, not just memorised answers.
+- **In line with the base's capability.** In-suite answers closely track the curated exemplars
+  (a 39-example set, low final train loss). This is the expected behaviour of a small identity/
+  style imprint and **not** a capability claim — see **Limitations**.
+
+Reproduce: `python training/train_lora.py && NG_MODEL=./naderu-geek-py-0.5b python eval/suites/naderu-geek/run_eval.py`
+<!-- EVAL:END -->
+
+This is a qualitative smoke check (identity recognised + coherent Python), not a
+leaderboard score. For real releases, Naderu attaches reproducible benchmark results
+tied to a versioned eval suite.
+
+## Limitations & risks
+
+- Tiny base (0.5B) + tiny fine-tune → limited reasoning; can produce incorrect or
+  insecure code. **Always review generated code.**
+- The fine-tune changes identity/style far more than capability.
+- English + Python focus; other languages are best-effort from the base.
+
+## About Naderu
+
+[**Naderu**](https://naderu.com) is an AI-models company — a venture of **BytesBrains Pte. Ltd.**
+We do three things, and only these:
+
+- **Train** — turn foundation models into specialised ones (fine-tune, LoRA, distill, quantize).
+- **Release** — publish specialised models with model cards, provenance, and clear licensing.
+- **Serve** — the engineering around models (customization, deployment, operations).
+
+Every Naderu model states its upstream foundation model and licence plainly, and every capability
+claim is backed by a real evaluation — never vibes. `naderu-geek-py-0.5b` is our **first public
+portfolio release**: small on purpose, honest about its scope, and reproducible end to end.
