# 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)
