This is a sentence-transformers model finetuned from BAAI/bge-m3. It maps sentences & paragraphs to a 1024-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    "What factors are contributing to pressure on Apple's market share in China?",
    "The company forecast low-to-mid single-digit\nrevenue growth, in line with muted expectations. In China, Apple posted $16 billion in revenue, slightly\nabove forecasts, though competition from Huawei and slower AI\nrollout continue to pressure market share. If losses hold, Apple is on track to shed more than $150\nbillion in market value, while a bullish outlook from Microsoft\n<MSFT.O> earlier this week has helped the Windows-maker become\nthe world's most valuable company.",
    'With recent\nexchange rate fluctuations adding to the uncertainty, we are\ntaking a more cautious outlook for the near future." While Washington and Beijing on Monday agreed to slash\ntariffs for at least 90 days, the cheer over the temporary truce\nwas tempered by caution given a more permanent trade deal needs\nto be struck, while higher tariffs overall could still weigh on\nthe global economy. Most of the iPhones Foxconn makes for Apple are assembled in\nChina.',

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)

`By approximately what percentage did Meta's shares increase in after-hours trading following the announcement of its results?`	`Its shares[object Object]jumped around 7% in after-hours trade on the news of the results. Meanwhile,[object Object]Meta beat estimates with $42 billion in revenue last quarter. It's also said[object Object]its daily active users across Facebook, Instagram, and the rest of its[object Object]services rose 6% year-on-year, marking welcome news for advertisers.`
`How have drugmakers responded to proposed tariffs on imported pharmaceutical products during the Commerce Department's investigation?`	The move triggered a 21-day public comment period as part of[object Object] the investigation led by the Commerce Department. Drugmakers see the probe as a chance to show the[object Object]administration that high tariffs would hinder their efforts to[object Object]swiftly ramp up U.S. production, and to propose alternatives,[object Object]said Ted Murphy, a trade lawyer at law firm Sidley Austin, which[object Object]is advising companies on their submissions to the Commerce[object Object]Department. Drugmakers have also lobbied Trump to phase in tariffs on[object Object]imported pharmaceutical products in hopes of reducing the sting[object Object]from the charges.
`Which South American companies currently use the company's regional services, and what growth expectations does Estevez have for the area?`	The company already has 36 regions and 114 availability[object Object]zones worldwide used by companies such as Netflix, General[object Object]Electric and Sony for storage, networking and remote security. Chilean retailer Cencosud, online retail giant MercadoLibre,[object Object]and mining companies already use the company's other regional[object Object]services, it said. Amazon's first-quarter cloud revenue and income forecast[object Object]came in below estimates last Thursday, but Estevez said he's[object Object]expecting strong growth in Chile and across the region.
