BioBERT v1.2 (Biomedical Embeddings) is embeddings AI model from huggingface, priced at €0.000 per 1M input tokens with a 512 tokens context window.

About this model

BioBERT continues pretraining of the cased English BERT-base model on large biomedical corpora (PubMed abstracts), keeping the original vocabulary so it stays compatible with general-domain BERT while gaining biomedical knowledge. Version 1.2 is the cased release maintained by DMIS-Lab. It was one of the first domain-adapted BERTs and remains a standard baseline for biomedical NLP. Served through Hugging Face with the feature-extraction pipeline, returning token-level hidden states; pool them for sentence or document embeddings.

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.
