Llama3 Cookbook¶

Meta developed and released the Meta Llama 3 family of large language models (LLMs), a collection of pretrained and instruction tuned generative text models in 8 and 70B sizes. The Llama 3 instruction tuned models are optimized for dialogue use cases and outperform many of the available open source chat models on common industry benchmarks.

In this notebook, we will demonstrate how to use Llama3 with LlamaIndex. Here, we use Llama-3-8B-Instruct for the demonstration."

hf_token = "hf_"

hf_token = "hf_"

Setup Tokenizer and Stopping ids¶

In [ ]:

from transformers import AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained(
    "meta-llama/Meta-Llama-3-8B-Instruct",
    token=hf_token,
)

stopping_ids = [
    tokenizer.eos_token_id,
    tokenizer.convert_tokens_to_ids("<|eot_id|>"),
]

from transformers import AutoTokenizer tokenizer = AutoTokenizer.from_pretrained( "meta-llama/Meta-Llama-3-8B-Instruct", token=hf_token, ) stopping_ids = [ tokenizer.eos_token_id, tokenizer.convert_tokens_to_ids("<|eot_id|>"), ]

Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.

The moment of truth! I am thrilled to introduce LLaMA3, the latest breakthrough in conversational AI from MetaAI. This revolutionary model is the culmination of years of research and innovation in natural language processing, and we believe it has the potential to transform the way humans interact with machines.

LLaMA3 is a large-scale, multimodal language model that can understand and respond to human input in a more nuanced and context-aware manner than ever before. With its massive language understanding capabilities, LLaMA3 can engage in conversations that are indistinguishable from those with a human. It can understand sarcasm, idioms, and even subtle emotional cues, making it an invaluable tool for a wide range of applications.

But what really sets LLaMA3 apart is its ability to integrate with other forms of media, such as images, videos, and audio. This multimodal capability enables LLaMA3 to provide more comprehensive and contextual responses, making it an ideal solution for tasks like customer service, content creation, and even artistic collaboration.

Some of the key features of LLaMA3 include:

1. **Conversational fluency**: LLaMA3 can engage in natural-sounding conversations, using context and understanding to respond to questions and

 Paul Graham worked on writing and programming outside of school. He wrote short stories and tried writing programs on the IBM 1401, which was used for data processing in his school district. He and his friend Rich Draves got permission to use the 1401 in the basement of their junior high school. He was puzzled by the 1401 and couldn't figure out what to do with it, but later got a microcomputer and started programming. He also worked on model rockets and did some painting.  He didn't plan to study programming in college, but instead studied philosophy, which he found boring. He then switched to AI and started writing essays.  He worked on various projects, including building an office in a former candy factory and having dinner parties for his friends.  He also started Y Combinator with Jessica Livingston and Robert Tappan Morris.  He wrote many essays, which were later collected into a book called Hackers & Painters.  He also worked on spam filters and continued to paint.  He gave talks and realized that he should stop procrastinating about angel investing, which led to the founding of Y Combinator.
