# SciEmbed-BASE

Signal A only (citation edges), 7M pairs, 3 epochs. The citation-edge baseline that isolates what Signal B adds.

A 149M-parameter ModernBERT-base scientific document embedder trained with citation-context sentences as the primary contrastive signal. Part of the **SciEmbed** release (paper under double-blind review; author info omitted).

## Usage

```python
from sentence_transformers import SentenceTransformer

model = SentenceTransformer("anon-nlp/sciembed-base")
emb = model.encode(["citation-context supervision for scientific embeddings"],
                   normalize_embeddings=True)
```

- **Context length:** 512 tokens
- **Pooling:** mean · **Output dim:** 768 (Matryoshka-truncatable to 512/256/128)
- **License:** MIT
