Introduction to embed-english-light-v3.0
embed-english-light-v3.0
is a smaller and faster version of embed-english-v3.0
. Almost as capable, but a lot faster. Tailored for English text.
Comparing all embedding models in the Embed V3 model series.
Model Name | Dimensions | MTEB Performance (higher is better) | BEIR Performance (higher is better) |
---|---|---|---|
embed-english-v3.0 | 1024 | 64.5 | 55.9 |
embed-english-light-3.0 | 384 | 62.0 | 52.0 |
embed-multilingual-v3.0 | 1024 | 64.0 | 54.6 |
embed-multilingual-light-v3.0 | 384 | 60.1 | 50.9 |
embed-multilingual-v2.0 | 768 | 58.5 | 47.1 |
- MTEB: Broad dataset for evaluating retrievals, classification, and clustering (56 datasets)
- BEIR: Dataset focused on out-of-domain retrievals (14 datasets)
How to create vector embeddings with embed-english-light-v3.0
There are two primary ways to generate vector embeddings:
- PyMilvus: the Python SDK for Milvus that seamlessly integrates the
embed-english-light-v3.0
model. - Cohere Python SDK: the python SDK offered by Cohere.
Once the vector embeddings are generated, they can be stored in Zilliz Cloud (a fully managed vector database service powered by Milvus) and used for semantic similarity search. Here are four key steps:
- Sign up for a Zilliz Cloud account for free.
- Set up a serverless cluster and obtain the Public Endpoint and API Key.
- Create a vector collection and insert your vector embeddings.
- Run a semantic search on the stored embeddings.
