SentenceTransformer based on Snowflake/snowflake-arctic-embed-l

This is a sentence-transformers model finetuned from Snowflake/snowflake-arctic-embed-l. 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.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("Gonalb/legal-ft-v0")
# Run inference
sentences = [
    'What does the cost of training the DeepSeek v3 model suggest about the future of training costs for AI models?',
    'I think this means that, as individual users, we don’t need to feel any guilt at all for the energy consumed by the vast majority of our prompts. The impact is likely neglible compared to driving a car down the street or maybe even watching a video on YouTube.\nLikewise, training. DeepSeek v3 training for less than $6m is a fantastic sign that training costs can and should continue to drop.\nFor less efficient models I find it useful to compare their energy usage to commercial flights. The largest Llama 3 model cost about the same as a single digit number of fully loaded passenger flights from New York to London. That’s certainly not nothing, but once trained that model can be used by millions of people at no extra training cost.',
    'Large Language Models\nThey’re actually quite easy to build\nYou can run LLMs on your own devices\nHobbyists can build their own fine-tuned models\nWe don’t yet know how to build GPT-4\nVibes Based Development\nLLMs are really smart, and also really, really dumb\nGullibility is the biggest unsolved problem\nCode may be the best application\nThe ethics of this space remain diabolically complex\nMy blog in 2023',

embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

  <code>What tools did the author describe in their writing about Claude Artifacts?</code>	<code>I’ve found myself using this a lot. I noticed how much I was relying on it in October and wrote Everything I built with Claude Artifacts this week, describing 14 little tools I had put together in a seven day period.<br>Since then, a whole bunch of other teams have built similar systems. GitHub announced their version of this—GitHub Spark—in October. Mistral Chat added it as a feature called Canvas in November.<br>Steve Krouse from Val Town built a version of it against Cerebras, showcasing how a 2,000 token/second LLM can iterate on an application with changes visible in less than a second.</code>

  <code>Why does the author find the term "agents" extremely frustrating?</code>	<code>“Agents” still haven’t really happened yet<br>I find the term “agents” extremely frustrating. It lacks a single, clear and widely understood meaning... but the people who use the term never seem to acknowledge that.<br>If you tell me that you are building “agents”, you’ve conveyed almost no information to me at all. Without reading your mind I have no way of telling which of the dozens of possible definitions you are talking about.</code>
