sciembed-nodapt-ctx
anon-nlp/sciembed-nodapt-ctx
sciembed-nodapt-ctx is a feature extraction model from anon-nlp. Use it when you need embeddings to search or compare text. It is set up for sentence-transformers. The card lists the license as mit.
The CTX recipe with Stage 1 (domain-adaptive MLM) skipped — contrastive straight off ModernBERT-base. Shows DAPT adds only ~0.1 once Signals A+B are present.

SciEmbed-NoDAPT-CTX
The CTX recipe with Stage 1 (domain-adaptive MLM) skipped — contrastive straight off ModernBERT-base. Shows DAPT adds only ~0.1 once Signals A+B are present.
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
from sentence_transformers import SentenceTransformer
model = SentenceTransformer("anon-nlp/sciembed-nodapt-ctx")
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)
