# Wind Arc 1.5 — Preview

An early experimental release from the Wind Arc line. **This model is significantly behind Wind Edge 1.6** — treat it as a research artifact, not a usable assistant.

**[North ML](https://huggingface.co/north-ml1)** · [Wind Edge 1.6 – Geode](https://huggingface.co/north-ml1/wind-edge-1.6-gguf)

> ⚠️ Preview release. Underperforms Wind Edge 1.6 by roughly 50% across benchmarks. Not recommended for any practical use.

---

## Overview

Wind Arc 1.5 Preview exists to document an early training run and architectural experiment. It is not a capable model by any standard measure. Published for transparency and research continuity — the stable Wind Arc line will be a full rebuild.

## Benchmark Results

| Task | Score | Notes |
|------|-------|-------|
| MMLU (boosted) | 0.08 / 1.00 | Boosted eval with few-shot scaffolding |

> **On MMLU:** 0.08 on a boosted protocol means near-random performance even with prompt engineering assistance. Raw 0-shot will score lower. Wind Edge 1.6 scores roughly 2× this across comparable tasks. This model is not competitive.

## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("arthu1/wind-arc-1-5-preview")
tokenizer = AutoTokenizer.from_pretrained("arthu1/wind-arc-1-5-preview")

inputs = tokenizer("You are Wind Arc, a helpful AI assistant.\nUser: ", return_tensors="pt")
output = model.generate(**inputs, max_new_tokens=512, temperature=0.6, top_p=0.9)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```

### Chat Template

## Why Publish This?

Wind Arc 1.5 Preview is published as a training checkpoint for research reference. The gap between this and Wind Edge 1.6 informs the architectural changes planned for the stable Wind Arc release.
