avaldaja Jina AI

ColBERT multi-embedding model for text input of size up to 8192 tokens.

  • jina-colbert-v1-en is an open-source English ColBERT-style embedding model supporting 8192 sequence length.
  • ColBERT (Contextualized Late Interaction over BERT) leverages the deep language understanding of BERT while introducing a novel interaction mechanism. This mechanism, known as late interaction, allows for efficient and precise retrieval by processing queries and documents separately until the final stages of the retrieval process.
  • This state-of-the-art AI embedding model enables many applications, such as document clustering, classification, content personalization, vector search, or retrieval augmented generation.

Highlights:

  • Jina-colbert-v1-en's main advancement is its backbone, jina-bert-v2-base-en, which enables processing of significantly longer contexts (up to 8192 tokens) compared to the original ColBERT that uses bert-base-uncased. This capability is crucial for handling documents with extensive content, providing more detailed and contextual search results.

  • jina-colbert-v1-en's has a superior performance, especially in scenarios requiring longer context lengths vs the original ColBERTv2. Note that jina-embeddings-v2-base-en uses more training data, whereas jina-colbert-v1-en only uses MSMARCO, which may justify the good performance of jina-embeddings-v2-base-en on some tasks.

  • Use-cases: Fine-grained vector search, retrieval augmented generation, long document clustering, sentiment analysis.
