E5-mistral-7b-instruct

Improving Text Embeddings with Large Language Models. Liang Wang, Nan Yang, Xiaolong Huang, Linjun Yang, Rangan Majumder, Furu Wei, arXiv 2024

This model has 32 layers and the embedding size is 4096.

Usage

Below is an example to encode queries and passages from the MS-MARCO passage ranking dataset.

Sentence Transformers

from sentence_transformers import SentenceTransformer

model = SentenceTransformer("intfloat/e5-mistral-7b-instruct")
# In case you want to reduce the maximum sequence length:
model.max_seq_length = 4096

queries = [
    "how much protein should a female eat",
    "summit define",
]
documents = [
    "As a general guideline, the CDC's average requirement of protein for women ages 19 to 70 is 46 grams per day. But, as you can see from this chart, you'll need to increase that if you're expecting or training for a marathon. Check out the chart below to see how much protein you should be eating each day.",
    "Definition of summit for English Language Learners. : 1  the highest point of a mountain : the top of a mountain. : 2  the highest level. : 3  a meeting or series of meetings between the leaders of two or more governments."
]

query_embeddings = model.encode(queries, prompt_name="web_search_query")
document_embeddings = model.encode(documents)

scores = (query_embeddings @ document_embeddings.T) * 100
print(scores.tolist())

Have a look at config_sentence_transformers.json for the prompts that are pre-configured, such as web_search_query, sts_query, and summarization_query. Additionally, check out unilm/e5/utils.py for prompts we used for evaluation. You can use these via e.g. model.encode(queries, prompt="Instruct: Given a claim, find documents that refute the claim\nQuery: ").
