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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("njhaveri/legal-ft-2")
# Run inference
sentences = [
    'What are some of the new features introduced in multi-modal models that enhance their capabilities beyond text?',
    'I think people who complain that LLM improvement has slowed are often missing the enormous advances in these multi-modal models. Being able to run prompts against images (and audio and video) is a fascinating new way to apply these models.\nVoice and live camera mode are science fiction come to life\nThe audio and live video modes that have started to emerge deserve a special mention.\nThe ability to talk to ChatGPT first arrived in September 2023, but it was mostly an illusion: OpenAI used their excellent Whisper speech-to-text model and a new text-to-speech model (creatively named tts-1) to enable conversations with the ChatGPT mobile apps, but the actual model just saw text.',
    '260 input tokens, 92 output tokens. Cost approximately 0.0024 cents (that’s less than a 400th of a cent).\nThis increase in efficiency and reduction in price is my single favourite trend from 2024. I want the utility of LLMs at a fraction of the energy cost and it looks like that’s what we’re getting.\nMultimodal vision is common, audio and video are starting to emerge\nMy butterfly example above illustrates another key trend from 2024: the rise of multi-modal LLMs.\nA year ago the single most notable example of these was GPT-4 Vision, released at OpenAI’s DevDay in November 2023. Google’s multi-modal Gemini 1.0 was announced on December 7th 2023 so it also (just) makes it into the 2023 window.',
]
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]

`Why is it important for language models to believe the information provided to them?`	Language Models are gullible. They “believe” what we tell them—what’s in their training data, then what’s in the fine-tuning data, then what’s in the prompt.[object Object]In order to be useful tools for us, we need them to believe what we feed them![object Object]But it turns out a lot of the things we want to build need them not to be gullible.[object Object]Everyone wants an AI personal assistant. If you hired a real-world personal assistant who believed everything that anyone told them, you would quickly find that their ability to positively impact your life was severely limited.
`What are the potential drawbacks of having a language model that is overly gullible?`	Language Models are gullible.

`What significant change occurred in LLM pricing over the past twelve months?`	Here’s the rest of the transcript. It’s bland and generic, but my phone can pitch bland and generic Christmas movies to Netflix now![object Object]LLM prices crashed, thanks to competition and increased efficiency[object Object]The past twelve months have seen a dramatic collapse in the cost of running a prompt through the top tier hosted LLMs.[object Object]In December 2023 (here’s the Internet Archive for the OpenAI pricing page) OpenAI were charging $30/million input tokens for GPT-4, $10/mTok for the then-new GPT-4 Turbo and $1/mTok for GPT-3.5 Turbo.
