| # LFM2-ColBERT-350M |
|
|
| LFM2-ColBERT-350M is a late interaction retriever with excellent multilingual performance. It allows you to store documents in one language (for example, a product description in English) and retrieve them in many languages with high accuracy. |
|
|
| - LFM2-ColBERT-350M offers **best-in-class accuracy** across different languages. |
| - Inference speed is **on par with models 2.3 times smaller**, thanks to the efficient LFM2 backbone. |
| - You can use it as a **drop-in replacement** in your current RAG pipelines to improve performance. |
|
|
| Find more information about LFM2-ColBERT-350M in our [blog post](http://www.liquid.ai/blog/lfm2-colbert-350m-one-model-to-embed-them-all). |

|
|
| ## 📄 Model details |
|
|
| Late interaction retrievers like LFM2-ColBERT-350M are particularly interesting because they preserve much of the **expressivity** of re-rankers while retaining the **efficiency** of bi-encoders. |
| In practice, they're used to both retrieve documents at scale (like bi-encoders) and rank them at the same time (like rerankers). |
|
|
|  |
|
|
| We recommend using this model for various RAG use cases, such as: |
|
|
| - **E-commerce**: Find products across many languages with semantic search at scale. |
| - **On-device semantic search**: Ask questions to your phone in natural language to retrieve files, emails, and notes. |
| - **Enterprise knowledge assistants**: Retrieve internal legal, financial, and technical documents in different languages. |

| ## 🏃 How to run |
|
|
| <a href="https://colab.research.google.com/drive/1tXSAXGpjuTvliuTrSSHDEcmIe48uolrD?usp=sharing"><img src="https://cdn-uploads.huggingface.co/production/uploads/61b8e2ba285851687028d395/vlOyMEjwHa_b_LXysEu2E.png" width=120 alt="Colab link"></a> |
|
|
| First, install the PyLate and transformers library: |
|
|
| ```bash |
| pip install -U pylate |
| ``` |
|
|
| ### Retrieval |
|
|
| Use this model with PyLate to index and retrieve documents. The index uses [FastPLAID](https://github.com/lightonai/fast-plaid) for efficient similarity search. |
|
|
| #### Indexing documents |
|
|
| Load LFM2-ColBERT-350M and initialize the PLAID index, then encode and index your documents: |
|
|
| ```python |
| from pylate import indexes, models, retrieve |
| |
| # Step 1: Load the ColBERT model |
| model = models.ColBERT( |
| model_name_or_path="LiquidAI/LFM2-ColBERT-350M", |
| ) |
| model.tokenizer.pad_token = model.tokenizer.eos_token |
| |
| # Step 2: Initialize the PLAID index |
| index = indexes.PLAID( |
| index_folder="pylate-index", |
| index_name="index", |
| override=True, # This overwrites the existing index if any |
| ) |
| |
| # Step 3: Encode the documents |
| documents_ids = ["1", "2", "3"] |
| documents = ["document 1 text", "document 2 text", "document 3 text"] |
| |
| documents_embeddings = model.encode( |
| documents, |
| batch_size=32, |
| is_query=False, # Ensure that it is set to False to indicate that these are documents, not queries |
| show_progress_bar=True, |
| ) |
| |
| # Step 4: Add document embeddings to the index by providing embeddings and corresponding ids |
| index.add_documents( |
| documents_ids=documents_ids, |
| documents_embeddings=documents_embeddings, |
| ) |
| ``` |
|
|
| Note that you do not have to recreate the index and encode the documents every time. Once you have created an index and added the documents, you can re-use the index later by loading it: |
|
|
| ```python |
| # To load an index, simply instantiate it with the correct folder/name and without overriding it |
| index = indexes.PLAID( |
| index_folder="pylate-index", |
| index_name="index", |
| ) |
| ``` |
|
|
| #### Retrieving top-k documents for queries |
|
|
| Once the documents are indexed, you can retrieve the top-k most relevant documents for a given set of queries. |
| To do so, initialize the ColBERT retriever with the index you want to search in, encode the queries and then retrieve the top-k documents to get the top matches ids and relevance scores: |
|
|
| ```python |
| # Step 1: Initialize the ColBERT retriever |
| retriever = retrieve.ColBERT(index=index) |
| |
| # Step 2: Encode the queries |
| queries_embeddings = model.encode( |
| ["query for document 3", "query for document 1"], |
| batch_size=32, |
| is_query=True, # # Ensure that it is set to True to indicate that these are queries |
| show_progress_bar=True, |
| ) |
| |
| # Step 3: Retrieve top-k documents |
| scores = retriever.retrieve( |
| queries_embeddings=queries_embeddings, |
| k=10, # Retrieve the top 10 matches for each query |
| ) |
| ``` |
|
|
| ### Reranking |
| If you only want to use LFM2-ColBERT-350M to perform reranking on top of your first-stage retrieval pipeline without building an index, you can simply use rank function and pass the queries and documents to rerank: |
|
|
| ```python |
| from pylate import rank, models |
| |
| queries = [ |
| "query A", |
| "query B", |
| ] |
| |
| documents = [ |
| ["document A", "document B"], |
| ["document 1", "document C", "document B"], |
| ] |
| |
| documents_ids = [ |
| [1, 2], |
| [1, 3, 2], |
| ] |
| |
| model = models.ColBERT( |
| model_name_or_path="LiquidAI/LFM2-ColBERT-350M", |
| ) |
| |
| queries_embeddings = model.encode( |
| queries, |
| is_query=True, |
| ) |
| |
| documents_embeddings = model.encode( |
| documents, |
| is_query=False, |
| ) |
| |
| reranked_documents = rank.rerank( |
| documents_ids=documents_ids, |
| queries_embeddings=queries_embeddings, |
| documents_embeddings=documents_embeddings, |
| ) |
| ``` |
|
|
| ## 📈 Performance |
|
|
| ### Accuracy |
|
|
| We extended the NanoBEIR benchmark to include Japanese and Korean languages. We open-sourced this dataset on Hugging Face at [LiquidAI/nanobeir-multilingual-extended](https://huggingface.co/datasets/LiquidAI/nanobeir-multilingual-extended) for reproducibility. |
| On this NanoBEIR benchmark, LFM2-ColBERT-350M displays significantly stronger multilingual capabilities (especially in German, Arabic, Korean, and Japanese) while maintaining English performance. |
|
|
|  |
|
|
| Even more interestingly, LFM2-ColBERT-350M is an excellent cross-lingual retriever. This means that it is capable of retrieving documents based on queries from other languages. This is ideal for client-facing applications, like in e-commerce, where a description might be in English but the query is in another language. |
|
|
| LFM2-ColBERT-350M works especially well for English, French, Spanish, Italian, Portuguese, and German, as shown with these NDCG@10 scores on NanoBEIR: |

|
| This makes retrieval a lot more reliable and can replace architectures with multiple models with a single, unified retriever. |
|
|
| ### Inference speed |
|
|
| Despite being more than twice as big, LFM2-ColBERT-350M demonstrates throughput performance on par with GTE-ModernColBERT-v1 for query and document encoding across various batch sizes. |
|
|
| Query encoding was evaluated using realistic query patterns from datasets like MS MARCO and Natural Questions. |
|
|
|  |
|
|
| Document encoding was measured on realistic documents with varying lengths and domains. |
