SciEmbed-FULL

Headline model. Stage 1 DAPT + contrastive on the ~30M-pair Signal A+B pool (1 epoch). The SciRepEval number in the paper is the mean over three seeds; this repo ships the seed-123 weights.

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-full")
emb = model.encode(["citation-context supervision for scientific embeddings"],
                   normalize_embeddings=True)

—Context length: 512 tokens
