SciEmbed-CTX-2048
Intermediate long-context variant (max_seq_length=2048). Point on the 512→2K→8K context-length scan.
A 149M-parameter ModernBERT-base scientific document embedder trained with citation-context sentences as the primary contrastive signal. Part of the SciEmbed release (Findings of EMNLP 2026).
Usage
from sentence_transformers import SentenceTransformer
model = SentenceTransformer("J0nasW/sciembed-ctx-2048")
emb = model.encode(["citation-context supervision for scientific embeddings"],
normalize_embeddings=True)
- Context length: 2048 tokens
- Pooling: mean · Output dim: 768 (Matryoshka-truncatable to 512/256/128)
- License: MIT
