SciBERT (scivocab uncased)

huggingface
Embeddings

AllenAI BERT-base pretrained from scratch on 1.14M scientific papers (mostly biomedical and computer science) with its own scientific WordPiece vocabulary. Used as a feature extractor it gives 768-dim contextual embeddings tuned to scientific text, outperforming general BERT on tasks like NER and relation extraction in research corpora.

SciBERT (scivocab uncased) is embeddings AI model from huggingface, priced at €0.000 per 1M input tokens with a 512 tokens context window.

About this model

SciBERT is a BERT-base model trained on a large corpus of full-text scientific papers from Semantic Scholar. Unlike vanilla BERT it uses scivocab, a WordPiece vocabulary built directly from scientific text, which improves token coverage for domain terminology. This scivocab-uncased checkpoint is the most downloaded variant. Through the Hugging Face feature-extraction pipeline it returns token-level hidden states; mean-pool or take the [CLS] vector for sentence or document embeddings in scientific search and classification pipelines.

BGE Large EN v1.5

huggingface

BAAI (Beijing Academy of AI) open-weight English embedding model with 335M parameters. Returns 1024-dim vectors and was a top MTEB English retrieval model on release. The v1.5 update improved similarity distribution so it works well without a query instruction prefix for symmetric tasks. A widely used open alternative to hosted embeddings.

BGE-M3 (Multilingual)

huggingface

BAAI multilingual embedding model covering 100+ languages with an 8192-token context. M3 stands for its multi-functionality (dense, sparse and ColBERT-style multi-vector retrieval), multilinguality and multi-granularity over long documents. Returns 1024-dim dense vectors and is a strong open choice for cross-lingual and long-text retrieval.

ESM-2 650M (Protein Embeddings)

huggingface

Meta AI 650M-parameter protein language model trained on UniRef50 sequences. Feed it an amino-acid sequence and the per-residue hidden states act as learned protein embeddings, used for structure prediction, variant-effect and function tasks. This 33-layer checkpoint is the common balance of quality and cost in the ESM-2 family.

Nomic Embed Text v1.5

huggingface

Nomic AI open embedding model with a fully reproducible training pipeline (open weights, data and code). Supports an 8192-token context and Matryoshka representation learning, so you can truncate the 768-dim output down to 64 dims with graceful quality loss. Uses task prefixes like search_query and search_document.
