**🎯 Intended Use**

This model is designed for **step‑by‑step reasoning tasks** where the answer requires logical decomposition before the final response. It is optimized for:

- **Educational applications** — explaining "why" and "how" questions
- **On‑device assistants** — runs on mobile, Raspberry Pi, or CPU‑only environments
- **Fast prototyping** — small footprint (0.9B parameters), low latency
- **Reasoning distillation research** — studying how small models learn from large ones (Ling → Qwen)

**Not recommended for:** multimodal tasks, non‑reasoning chat (e.g., creative writing), or production systems requiring 100% factual accuracy.

---

**⚠️ Limitations & Intended Use**

Intended Use:

* Educational & Reasoning tasks — explaining step‑by‑step logic (math, science, common sense)

* On‑device assistants — runs on CPU, Raspberry Pi, mobile (small footprint, fast inference)

* Research baseline — for studying SFT‑only reasoning without RLHF/DPO

* Distillation experiments — testing how well small models learn from large (Ling → Qwen)

Limitations:

* Size matters — 0.9B parameters, so complex or multi‑hop reasoning may still fail

* No multimodal — text only; images, video, audio are not supported

* Factual accuracy — may hallucinate or give incorrect answers; always verify critical outputs

* Domain restricted — trained on **15,000** reasoning examples (2.5 epochs); general chat or creative writing may be suboptimal

* Training data bias — inherits biases from `constructai/Ling-v2.6-Flash-Distilled-15K` dataset; not safety‑filtered for harmful content

* Hardware specific — optimised for T4/consumer GPUs; very slow on CPU without quantisation
