**Pulpie Orange Base** extracts the main content from raw HTML, stripping navigation, ads, sidebars, and footers. It is an encoder that labels every HTML block as content or boilerplate in a single forward pass, so it approaches state-of-the-art extraction quality while running far faster and cheaper than autoregressive extractors.

At 610M parameters it sits between [Orange Small](https://huggingface.co/feyninc/pulpie-orange-small) and [Orange Large](https://huggingface.co/feyninc/pulpie-orange-large), scoring 0.863 ROUGE-5 F1. For most use cases Orange Small offers a better speed/quality trade-off; choose Base when you want a little more headroom than Small without the cost of the 2.1B teacher.

## Usage

The easiest way to use this model is through the [`pulpie`](https://pypi.org/project/pulpie/) package:

```bash
pip install pulpie
```

```python
from pulpie import Extractor

extractor = Extractor(model="orange-base")
result = extractor.extract(html)

print(result.markdown)                # clean Markdown
print(result.html)                    # clean HTML
print(result.n_main, result.n_other)  # blocks kept vs dropped
```

`Extractor` auto-detects CUDA, Apple MPS, then CPU. See the [GitHub README](https://github.com/feyninc/pulpie) for batch and multi-GPU usage.

## How it works

Pulpie runs a four-stage pipeline:

1. **Simplify** — remove scripts, styles, and formatting noise; tag each block with a unique ID.
2. **Chunk** — pack blocks into sequences of up to 8,192 tokens separated by `<|sep|>` markers (~80% of pages fit in one chunk).
3. **Classify** — a single encoder forward pass labels every block (at its `<|sep|>` position) as content or boilerplate.
4. **Reconstruct** — return the kept blocks as HTML, or convert to Markdown.

This model is a token-classification head over [EuroBERT-610m](https://huggingface.co/EuroBERT/EuroBERT-610m), distilled from the 2.1B [Pulpie Orange Large](https://huggingface.co/feyninc/pulpie-orange-large) teacher (KL-divergence 0.7 + hard-label cross-entropy 0.3, temperature 2.0).
