For more details, including benchmark evaluation, hardware requirements, and inference performance, please refer to our Github.

Usage

📌 Tip: For NV-Embed-V2, using Transformers versions later than 4.47.0 may lead to performance degradation, as model_type=bidir_mistral in config.json is no longer supported.

We recommend using Transformers 4.47.0.

Sentence Transformers Usage

You can evaluate this model loaded by Sentence Transformers with the following code snippet:

import mteb
from sentence_transformers import SparseEncoder
model = SparseEncoder(
    "CSR-NV_Embed_v2-Clustering-Biorxiv_TwentyNews",
    trust_remote_code=True
)
model.prompts = {
    "BiorxivClusteringP2P.v2": "Instruct: Identify the main category of Biorxiv papers based on the titles and abstracts\nQuery:",
    "BiorxivClusteringS2S.v2": "Instruct: Identify the main category of Biorxiv papers based on the titles\nQuery:",
    "TwentyNewsgroupsClustering": "Instruct: Identify the topic or theme of the given news articles\nQuery:"
}
task = mteb.get_tasks(tasks=["BiorxivClusteringP2P.v2", "BiorxivClusteringS2S.v2", "TwentyNewsgroupsClustering"])
evaluation = mteb.MTEB(tasks=task)
evaluation.run(
    model, 
    eval_splits=["test"], 
    output_folder="./results/clustering", 
    show_progress_bar=True
    encode_kwargs={"convert_to_sparse_tensor": False, "batch_size": 8},
)  # MTEB don't support sparse tensors yet, so we need to convert to dense tensors
